having an attack of angle

alderemert · February 24, 2022, 03:43

Hello everyone,

I am trying to simulate a turbulent airflow around a cube which is (10x10x10)m with a flow degree of 45 degrees. I can do it without an angle with no problem but I don't know how I can give the angle in the simplest way?

I tried to do it by separating the velocity into its components and putting these values into the inlet. The problem is, when the flow is coming from the inlet only with an angle, almost half of the domain remains empty without a flow and the streamlines around the cube are not enough.

I'd be really glad if I can get some advice!

You could define the bottom and top bc as "inletOutlet" with the same velocity as the inlet.

In that way, flow would enter the entire domain regardless of the angle.
