Dear OpenFOAMers !
I have to solve following 3D case:
An oil-separator (cylindric) with an inlet and an outlet. In the middle of the cylinder, orthogonal to inlet and outlet, is a wall with three holes.
The case is steady-state end incompessible.
I've imported the mesh using fluent3DToFoam.
After setting of boundaries and fields I've tried to solve the case, but after 5th step I've got this error message:
