Hi,

I want to simulate a fluid flow that enters a room under an angle. I can't use a cylinder (which I rotated to achieve the right angle), because I am not able to use one end as an inlet and I don't know why. Can anybody help me out?

Inspect the geometry model as you might have created the surface only for cylinder.

Dear mr Birla,
Thank you for your response. All parts of my model are solid. After I made a union, I sometimes get the error that there is a segregated group. The flow also diverges regarding the model while it should become stationary... Do you know any other settings where I can take a look at? All hints are welcome...
