mjk is on a distinguished road
I have searched the forums but haven't found anything so I created this thread.

I have a circular inlet at a base of a cylinder blocked in its centre. (see pic1) I want to have a flow enter the inlet at a constant angle of 45 degrees (see pic2) I am not sure how I can specify the angle in OpenFOAM. I have tried breaking down the inlet velocity in x, y, z vectors but cannot maintain the 45degree angle around the inlet. e.g.

type fixedValue;
value uniform (x y z);

Do I have to implement my own BC? maybe use groovyBC?

Any help will be much appreciated.

Thanks.
