Hi,

I have a fan inside a room that I want to add a fan boundary condition to.

I assigned the interfaces in order to create the interior boundary condition to create the fan per the user guide.

However, I get an error:
WARNING: 537 pair(s) of adjacent faces with different orientation on zone 7.

Error: jump zone 7 has wrong types of cell zones (cell and cell).

5: Adjacent faces have different orientation: Face 187, zone 7, (ID: 34377811): at location ( 3.17346e-01, -3.33962e-01, 1.85309e+00).

I am not sure how to resolve this problem.

Can anybody give guidance on this issue?

Regards.
