// Class description:
|
|
//
|
|
// A FastAerosolSolid is a collection of fDroplet solids
|
|
// with positions set randomly by FastAerosol in a
|
|
// volume given by a bulk shape given by FastAerosol member
|
|
//
|
|
// The FastAerosol member fCloud handles the optimization
|
|
// (finding nearest droplet, populating the cloud) needed for
|
|
// efficient simulations.
|
|
//
|
|
// This class is heavily based on system solids.
