Hi Mohsen,

Did you find the cause of the error?

Thanks

Hi Mohsen,

Check your boundary condition and boundary file in polymesh.

definition of your patches in 0 and polyMesh should be same.

But the same face might have different boundary conditions in the 0 directory. For example, inlet might be set as freestream in k but zeroGradient in p. In this case, what should be the type for the inlet in the boundary file in polymesh?

It should be a type "patch"
Have a look at the user guide and use tutorials as examples.
