Reply To: Parallel Resolved Particle Questions
Dear James.
Did you define your particle system as SuperParticleSystem or just as ParticleSystem? This should solve your problem with creating particles on the boundary between blocks. The periodic boundary problem might also be affected by this, as the periodic boundary also requires communication between blocks.
Introducing a different collision operator is quite easy in OpenLB. These are defined in src/dynamics/collision.h, just check the other implementations for guidance. However, as the dynamics are cse-optimized, you will have to either remove the cse optimization or run it again after your implementation. The collsion operator is then used in porousBGKdynamics.h .
Regarding size of particles, a resolved particle should have a diameter of at least 3 cells.
Best regards,
Christoph
