Hi foamers.

In my case the size of particles diameter is larger than the width of first cell near the wall and wall interaction doesn't work fine, and lets the particle overlap with the wall, because center of the particles should be in the nearest cell of the wall.
How can I implement the code to correct this issue?

I also implement and change collisionModel->pairCollision to collisionModel->myWallCollision by commenting parcel-parcel interaction to use only wall interaction, but after some iteration, it crashed.
Note that my case is a 2d case and I'm using a cloud like kinematicCollidigCloud.

No problem. I solved this by using collision model.

As I said before I used pairCollision model by commenting parcel-parcel interaction to perform only wall interaction because of 2d case! but it crashed after some iteration.

I had to noticed that i used cyclic patch at inlet and outlet.
I tracked the particles in some cases and understood that the code crashed exactly when one particle hits the wall and cyclic patch together in the corner of the box.
So i started debugging and found that a piece of code (referred wallFace interactions) cause the problem. by commenting this part of code, model perform like a charm for me.
