Hi all

I'm trying to simulate interaction between vortex and an airfoil. How can i specify a vortex as a boundary condition?
the vortex will be move with free stream.


Best regards

You can specify a vortex as the superposition of a ideal fluid vortex and a constant flow with some CEL expressions. Look up the ideal flow vortex equation in a fluid mechanics textbook.
