Hi, I'm using the Free and Porous Media Flow module to simulate the fluid flow on the particle level. I used it for 2D condition and it worked. When I switched to 3D case, something weird happened. I can get the proper pressure gradient, but all the velocity is zero....

Any help would be greatly appreciated!
Attached is the model.
