This release of Geant4 requires and has been verified with
|
|
<A TARGET="ext" HREF="http://cern.ch/clhep/">CLHEP</A>, release <B>2.4.1.3</B>.
|
|
Use of a different CLHEP version may cause incorrect simulation results.<BR>
|
|
NOTE: an internal module of the relevant CLHEP classes is provided and can be
|
|
used as alternative to an external CLHEP library installation.<BR>
|
|
A configuration option allows a Geant4 installation to use the
|
|
<A HREF="https://gitlab.cern.ch/VecGeom/VecGeom/">VecGeom Library</A>
|
|
primitives, to replace the original Geant4 solids. VecGeom version
|
|
<B>1.1.5</B> is required when using such configuration.

<UL>
|
|
<LI>The default integration method for propagation in magnetic fields is
|
|
changed, to select between the new interpolation-capable integration
|
|
scheme, for shorter steps, and a helix-based scheme which is chosen for
|
|
steps larger than <TT>2*pi</TT> times the curvature radius at the initial
|
|
location.</LI>
|
|
<LI>Once integration in field require more than a threshold (default 200)
|
|
integration substeps within a single physical step, there is a relaxation
|
|
of the criteria which breaks the curved trajectory into linear segments
|
|
for intersecting with the setup's geometry.
|
|
This criteria is governed by the parameter <I>delta chord</I>.
|
|
Once the threshold is reached, its value is temporarily doubled.
|
|
So subsequent integration substeps are made so that a chord's sagitta is
|
|
now less than twice the <I>delta chord</I>.
|
|
<UL>
|
|
<LI>Every time the number of iterations reaches a new multiple of 100 (the
|
|
increase value), the maximum sagitta distance (delta chord) is again
|
|
temporarily doubled for the rest of this tracking step.</LI>
|
|
<LI>This affects only particles below the 'important' energy threshold when
|
|
using G4Transportation only, (currently not G4CoupledTransporation)
|
|
which would otherwise be abandoned after a set maximum number of
|
|
substeps (default=<TT>1000</TT>).</LI>
|
|
<LI>To control the previous behaviour, use the G4PropagatorInField's method
|
|
<TT>SetIterationsToIncreaseChordDistance()</TT> to set the number of
|
|
iterations between increase; note that the initial threshold is twice
|
|
this value. To restore previous behaviour set it to <TT>500</TT>.</LI>
|
|
<LI>In a multi-threaded application, each thread must change this threshold,
|
|
e.g. by calling this method in your G4UserRunAction's
|
|
<TT>BeginOfRunAction()</TT>.</LI>
|
|
<LI>This does not occur if the alternative transportation process
|
|
G4CoupledTransportation is used, i.e. when one or more parallel
|
|
geometries are created for scoring, event biasing, parallel mass
|
|
geometry or other use(s).</LI>
|
|
</UL></LI>
|
|
<LI>An application which uses an external gravitational field must enable the
|
|
use of gravity by calling G4Transportation's static method
|
|
<TT>EnableGravity()</TT>. This change was introduced in order to call
|
|
the <TT>ConfigureForTrack()</TT> method of G4FieldManager only for
|
|
charged particles by default. Example <I>field06</I> in
|
|
<TT>examples/extended/field</TT> illustrates this.</LI>

<H2>4. New Developments and Capabilities </H2>
|
|
|
|
<B>General</B>
|
|
<UL>
|
|
<LI>Reviewed G4PhysicsVector adding an additional Value() method option to
|
|
propagate down the known log-energy value. This helps avoiding log() calls
|
|
when log-vector is used.</LI>
|
|
<LI>Added functionality in G4DynamicParticle to provide log-kinetic energy
|
|
value, computed only on demand if its stored value is not up-to-date with
|
|
the kinetic energy. Reviewed EM processes to select the target atom by
|
|
making use of the already known log-energy value in the log-vector access.
|
|
Providing measurable CPU speedup.</LI>
|
|
<LI>Enhanced UI commands to now return proper return code when they are not
|
|
successful.</LI>
|
|
<LI>Introduced ability to perform leading particle biasing.</LI>
|
|
</UL>
|
|
|
|
<B>Analysis</B>
|
|
<UL>
|
|
<LI>Added a new factory function <TT>ManagerInstance()</TT> in G4Analysis,
|
|
which allows to create the analysis manager of the type selected via a
|
|
string argument and so to choose the output type at run time.</LI>
|
|
<LI>Switched the default Root n-tuple merge mode to new column-wise mode
|
|
with preserving rows and added a second, optional, argument in the
|
|
<TT>SetNtupleRowWise()</TT> function which can be used to override the
|
|
defaults.</LI>
|
|
</UL>
|
|
|
|
<B>Digitization & Hits</B>
|
|
<UL>
|
|
<LI>Added G4TScoreNtupleWriter and G4TScoreNtupleWriterMessenger which
|
|
implement storing hits collections of G4THitsMap type vith Geant4 analysis
|
|
tools, defined in G4VcoreNtupleWriter. Its usage is demonstrated in basic
|
|
examples B3 and B4d.</LI>
|
|
</UL>
|
|
|
|
<B>Geometry and Field</B>
|
|
<UL>
|
|
<LI>Enabled VecGeom wrapper for G4GenericPolycone, G4EllipticalTube,
|
|
G4EllipticalCone and G4Ellipsoid. Requiring VecGeom version 1.1.5.</LI>
|
|
<LI>Added support for writing out assemblies envelopes in GDML.</LI>
|
|
<LI>Added hooks for capability to navigate in <I>external</I> geometry with
|
|
custom navigation.</LI>
|
|
<LI>Completed the development of integration driver with 'interpolation'
|
|
capability.
|
|
It estimates the position, momentum (and potentially other state,
|
|
e.g. polarisation) at intermediate values of the integration interval.
|
|
During the integration, one or more intervals are used to move the track's
|
|
state. For each interval a different instance of the stepper is used.
|
|
Subsequent calls for intermediate points (e.g. to locate the intersection
|
|
of the curved trajectory with a boundary) use the interpolation capability
|
|
using the existing data (stored in the earlier stepping), instead of
|
|
re-integration which involves re-evaluating the field and equation of
|
|
motion. Note: currently this can be used only with G4DormandPrince745
|
|
Runge Kutta integration method.</LI>
|
|
<LI>Completed new multiplexing integration driver G4BFieldIntegrationDriver
|
|
for magnetic fields, that enables mixing between two methods (drivers)
|
|
based on the ratio of the proposed step length and the step curvature at
|
|
the track's initial position.
|
|
One method is selected for shorter steps, and a different method for steps
|
|
longer than <TT>2*pi</TT> (estimation for uniform field). The default driver
|
|
created in G4ChordFinder's constructor and G4FieldManager's
|
|
<TT>CreateChordFinder()</TT> now creates it; it uses the interpolation
|
|
driver with the Dormand Prince 5/4th order Runge-Kutta method for short
|
|
steps, and for longer steps it uses the G4HelixHeum method which can
|
|
integrate over a large number of helical turns in a sufficiently slowly
|
|
varying field.
|
|
Enabled by default stepping using interpolation in field propagation.</LI>

<UL>
|
|
<LI>Use Glauber-Gribov cross-sections for hyperons and anti-hyperons for
|
|
both elastic and inelastic hadron-nucleus interactions.</LI>
|
|
<LI>Extended hadron-nucleon cross-sections to charmed and bottom hadrons
|
|
(mesons and baryons). Note: these cross-sections are meant to be used
|
|
by Glauber-Gribov charmed and bottom hadron nuclear cross-sections, as
|
|
well as by the FTF string model for dealing with charmed and bottom
|
|
projectiles; however, the inelastic interactions of charmed and bottom
|
|
projectiles are not yet included in reference physics lists.</LI>
|
|
<LI>Removed tracking cut in hadron-elastic and use numerically safer
|
|
computation for very low-energy projectile.</LI>
|
|
<LI>Use FTFP also for the annihilation at rest of neutral anti-hadrons.</LI>
|
|
<LI>Added new gamma-nuclear model based on pre-compound de-excitation.</LI>
|

<LI>Added spontaneous fission channel in radioactive-decay.</LI>
|
|
<LI>High energy extension of the neutrino-electron cross sections,
|
|
for both charged-current and neutral-current interactions
|
|
(M_W and M_Z propagator factors and Glashow resonance), for all neutrino
|
|
and anti-neutrino flavours.</LI>

|
|
<B>Physics Lists</B>
|
|
<UL>
|
|
<LI>Changed transition region between hadronic string and intra-nuclear cascade
|
|
models: now it is <TT>[3, 6] GeV</TT> consistently for all particle types
|
|
(nucleons, pions, kaons, hyperons, ions and gammas; for anti-baryons,
|
|
instead, FTFP is still used for all energies). Note: this does not affect
|
|
the physics lists FTFP_BERT_ATL, NuBeam, ShieldingM, and those based on
|
|
INCLXX. Moreover, for the QGS-based physics lists, the transition between
|
|
FTFP and QGSP remains unchanged in the region <TT>[12, 25] GeV</TT>.</LI>
|
|
<LI>Added (consistently) RadioactiveDecay to all physics lists which use
|
|
NeutronHP. Note: this affects the physics lists FTFP_BERT_HP, QGSP_BERT_HP,
|
|
FTFP_INCLXX_HP and QGSP_INCLXX_HP, whereas Shielding, LBE, QGSP_BIC_HP and
|
|
QGSP_BIC_AllHP had it already.</LI>
|
|
<LI>A new stopping physics constructor (G4StoppingPhysicsFritiofWithBinaryCascade)
|
|
has been introduced, which uses Fritiof (FTF) coupled with Binary cascade
|
|
(BIC) for the anti-baryon annihilation at rest. It is used only in the
|
|
physics lists FTF_BIC and QGS_BIC.</LI>

|
<B>Visualization and Interfaces</B>
|
|
<UL>

<LI>Introducing cloud drawing style in visualization, using kernel algorithms
|
|
for generating points on the surface of volumes, by-passing polyhedral
|

<LI>Set minimum required CMake version to 3.8 to fully support C++17
|
|
on all systems. Addressing problem report
|
|
<A HREF="http://bugzilla-geant4.kek.jp/show_bug.cgi?id=2044">#2044</A>.</LI>
|
|
<LI>Updated Intel settings to support use of C++17 with Intel 19 when
|
|
using CMake-3.8-3.10. Versions from 3.11 fully support Intel 19/C++17.</LI>
|
|
<LI>Removed obsolete GEANT4_BUILD_MUONIC_ATOMS_IN_USE option
|
|
and associated configuration/compiler flags.</LI>
|
|
<LI>Promoting following pre-processor flags to fixed #defines in a new
|
|
header generated by CMake using the chosen build options to
|
|
<TT>#define/#undef</TT> as appropriate: G4USE_STD11, G4MULTITHREADED,
|
|
G4_STORE_TRAJECTORY, G4VERBOSE, GEANT4_USE_TIMEMORY.
|
|
Promoted VecGeom pre-processor flags to fixed <TT>#defines</TT> as well.
|
|
Ensuring the header is included by primary "global" category headers
|
|
so that all categories will pick up the changes transparently.
|
|
Removed use of add_definitions of CMAKE_CXX_FLAGS to set these flags
|
|
in Geant4 and client scripts.</LI>
|
|
<LI>Removed G4FPE_DEBUG from build mode "Debug". Added new build mode
|
|
"Debug_FPE" same as "Debug" mode but appending -DG4FPE_DEBUG.</LI>
|
|
<LI>Set OpenGL_GL_PREFERENCE to LEGACY, to prevent warning on
|
|
CMake >= 3.10, and keeping existing behaviour.</LI>
|
|
<LI>Only scope location of test executable when using a generator that
|
|
supports multi-config; allows tests to be run with Ninja Generator as
|
|
"ninja test".</LI>
|
|
<LI>Do not switch off CMAKE_CXX_EXTENSIONS in Geant4Config; not required
|
|
for client applications. Addresses problem report
|
|
<A HREF="http://bugzilla-geant4.kek.jp/show_bug.cgi?id=2002">#2002</A>.</LI>
|
|
<LI>Using target_XXX usage requirements to transport header paths and links.
|
|
Removed requirement to use complete include_directories chain in Module
|
|
sources.cmake files. Retain exported "Geant4_INCLUDE_DIR{S}" variables
|
|
in case clients use Root dictionary generation (which does not
|
|
understand usage requirements of targets until latest versions).
|
|
Removed remaining -D flags set via add_definitions, moving to
|
|
target_compile_definitions.</LI>
|
|
<LI>Namespace exported targets with "Geant4::" to enforce use of targets
|
|
and prevent accidental linkage via <TT>-lG4name</TT> expansion.</LI>
|
|
<LI>Migrate use of all external packages to use and refind exported targets,
|
|
with shim scripts to support CMake versions from 3.8 at build/use time.</LI>
|
|
<LI>Store build-time locations of used external packages in an optionally
|
|
installable CMake script for reuse, if present, by Geant4Config.cmake
|
|
in refinding packages.</LI>
|
|
<LI>Require MSVC 19.20 (Visual Studio 2019) or newer as minimum required
|
|
version to build Geant4 on Windows. Needed to support use full C++17
|
|
Standard. Default C++ Standard with MSVC is now C++17.</LI>
|
|
<LI>Removed old genwindef method of generating DLL symbol exports, as
|
|
minimum cmake version of 3.8 fully supports direct generation via
|
|
target properties.</LI>
|
|
<LI>Removed GEANT4_FORCE_QT4 option, deprecating Qt4 support. Retain
|
|
fallback to finding Qt4, emitting a CMake warning that use of Qt4 is
|
|
deprecated.</LI>
|
|
<LI>Disabled configuration for Wt UI/Vis driver, as no longer supported.</LI>
|
|
<LI>Updated scripts to support the TiMemory find_package COMPONENTS and
|
|
the INTERFACE library generation.</LI>
|
|
<LI>Fixed logic of setting up components in Geant4Config.cmake.

<LI>The following fixes and improvements affect both G4Transportation and
|
|
G4CoupledTransportation:<BR>
|
|
- Fixed issues related to resetting of looper flag and other state for
|
|
field propagation. Involved replacing check for 'Global' field with check for any field; this is
|
|
needed to ensure that propagator-in-field state is reset when the
|
|
setup inludes only local fields.
|
|
Ensure that looping flag is reset (false) when a force is not exerted
|
|
in <TT>G4CoupledTransportation::AlongStepGetPhysicalInteractionLength()</TT>;
|
|
before it was overwritten afterwards.

<A HREF="http://bugzilla-geant4.kek.jp/show_bug.cgi?id=2144">#2144</A>.<BR>
|
|
- Optimisation to avoid calling user field manager's
|
|
<TT>ConfigureForTrack()</TT> method, except if particle is charged,
|
|
or forces from magnetic moment or gravity are enabled.<BR>
|
|
- The change above introduces a new 'flag' to enable gravity fields.
|
|
The static method <TT>EnableGravity()</TT> in G4Transportation must be
|
|
called if the application uses gravity fields (calling this method
|
|
will enable both types of transportation to consider gravity.<BR>
|
|
- Added flag to optionally silence warning about looping tracks.
|
|
The method <TT>SetSilenceLooperWarnings()</TT> controls it.</LI>

Required for addition of External Navigation, which adds an 'external'

physical volume type (for use with an External sub-Navigator).</LI>

<LI>Revised G4LogicalVolume to cope with 'external' type of physical
|
|
volumes. Use stored volume type in <TT>CharacteriseDaughters()</TT>.
|
|
These revisions are independent and backward compatible.</LI>
|
|
<LI>G4LogicalVolume: added method <TT>ChangeDaughtersType()</TT> to change
|
|
the volume type for <TT>CharacterisedDaughters()</TT>. It enables the
|
|
user to turn over responsibility for navigation in that volume to an
|
|
external navigator.
|
|
This is for use when one or more daughter volumes are created as an
|
|
existing physical volume type (typically <TT>G4PVPlacement</TT>). It
|
|
can also be used to enable to create a (logical) volume which containts
|
|
a mixture of existing Geant4 physical volume types and user-created
|
|
'external' physical volume type (with type code <TT>kExternal</TT>):
|
|
Geant4 types must be created first, and then <TT>ChangeDaughtersType()</TT>
|
|
must be called to change the mother's attribute to <TT>kExternal</TT>.
|
|
Note: only one type of sub-navigator will be called to find a track's
|
|
intersection (or the location of a point) in all daughters of one
|
|
mother volume. The sub-navigator chosen will correspond to the volume
|
|
type assigned.</LI>

<LI>Fixed cases of implicit type conversions from size_t to G4int.</LI>

<LI>Use header-based <TT>#define/undef</TT> symbols to configure VecGeom

<LI>Improved information in G4Exceptions for particles stuck due to

<LI>Added hooks for capability to navigate in 'external' geometry:
|

new base class G4VExternalNavigation for external 'sub'-navigator;

new type of 'External' physical volume, to flag volumes for
|
|
external sub-navigator; revisions to G4Navigator to dispatch logical
|
|
volumes with daughters which are of 'external' physical-volume type.
|
|
An 'external' sub-navigator can be registered with G4Navigator;
|
|
'placement' and 'external' physical volumes cannot be currently
|
|
mixed inside the same logical volume.</LI>
|
|
<LI>Added <TT>Clone()</TT> method in G4Navigator, to allow for 'cloning' the
|
|
navigator for G4VIntersectionLocator's 'helper', and potentially for
|
|
worker threads.</LI>
|
|
<LI>G4TransportationManager: enable worker threads to clone G4Navigator if
|
|
needed. Keep first navigator created; by convention that will be the
|
|
navigator object of the master thread (or the only thread). Other
|
|
(worker) threads will clone the first navigator, if it has an external
|
|
sub-navigator registered. This ensures that they clone the ability to
|
|
navigate in 'external' volume descriptions.</LI>
|

<LI>G4MultiLevelLocator: avoid re-estimating endpoint if driver does not
|

re-integrate when <TT>AccurateAdvance()</TT> is called.</LI>

<LI>Introduced temporary 'relaxation' (increase) of the value of delta-chord,

in G4PropagatorInField, to enable larger steps, after a threshold number

<LI>Introducing cloud drawing style. New parameter candidate 'cloud' in

<TT>/vis/viewer/set/style</TT>.
|
|
Cloud drawing uses <TT>solid->GetPointOnSurface()</TT>,
|
|
i.e., uses kernel algorithms and by-passes polyhedral representations.
|
|
The solid is represented by a polymarker of dots. The default number of
|
|
points is 1000. This can be changed with the command
|
|
<TT>/vis/viewer/set/numberOfCloudPoints</TT>; the minimum number is 100.
|
|
Note that OpenGL has a fast algorithm for polymarker.

This allows us to use cloud style both as a choice or as fallback when
|

the polyhedral representation fails, for example, when BooleanProcessor

fails.</LI>

|
|
limit the extent over which the field is drawn. This would help, for

example, if drawing over the whole scene produced so many arrows or

the parameter <TT>nDataPointsPerHalfExtent</TT> is changed from 10 to 3,
