process-wise buffer for particle IDs Used to inform other processes when a particle needs to be removed/killed
| Type | Visibility | Attributes | Name | Initial | |||
|---|---|---|---|---|---|---|---|
| integer, | public, | allocatable | :: | val(:) |
explicit buffer for data to be transferred |
||
| integer, | public | :: | nParticles |
number of particles to exchange, depends on number of particles at the interface of two processes. nParticles can change at every time step! Buffer can hold data for at most maxParticles This one we keep fixed through the duration of the program to avoid de-allocating, re-allocating memory at every time step. |
