Hello Karimi,

Could you describe the problem in more details? This is a 2D flow? Could you describe the inlet, outlet, and wall boundary conditions?

What is the fluid? What are the fluid properties? Note that the ICFD solver assumes incompressibility. This assumption may cause a change in the results compared with Fluent.

Also, did you use a boundary layer in Fluent? What about ICFD? 

With the ICFD solver, the mesh is generated by the solver based on the surface mesh. Make sure to review the volume mesh (tet mesh) generated by the solver for size and element quality.
