Dear community,
I am currently trying to simulate a flow in a periodic domain. The periodic structure consists of (parts of) cylinders. ![]() ![]() For meshing the geometry I am using snappyHexMesh with a stl-geometry file. I am using the boundary conditions as explained here: Periodic Inlet/Outlet Boundary Condition Thus I try to prescribe a mean velocity (in x-direction) and want to obtain the pressure loss over the periodic structure. I thought that the flow in x-direction is periodic, i.e., inflow = outflow in the periodic domain. However, when I duplicate the domain in paraFoam, the flow profile at inlet and outlet is not the same. ![]() As one can see there is a discontinuity between the two parts of the periodic domain. Am I wrong to expect continuity of the velocity? The pressure drop looks OK. Attached you find my files for executing the case. Maybe someone of you can have a look if everything is correctly set up. If some more data are needed, please tell me. Thank you in advance for your answers and your help. Regards Sebastian ![]() |
