Hello everyone,

I am simulating a blood pump in which the some surfaces are in the form of curved surfaces (strips) and have little width (~ 1 mm).

I generate Hexa mesh in ICEM and then bring the *.msh file in to STAR CCM+. The simulated part is 1/8 of the whole model.
The problem occurs when I assign the periodic BC in STAR CCM + on the periodic pars. here some part of the periodic surfaces become like small pieces of wall...ATTACHED IMAGE

(I do not know if the surface mesh is removes or...) and after the solution the create local strange velocity profile.

can anyone tell my how to solve this problem in ICEM to avoid this small walls
