Hi all,

I want my UDF to be able to set one half of a face to a velocity and the other half of the face to the wall boundary condition.

I have my udf to set the velocity on one half but I do not know how to set a wall boundary condition on the other.

I am running inviscid flow also.

i currently have the other half set to zero velocity, but this is inaccurate as I want there to be a wall or slip condition there.

can anyone help?

Hi

I have the same problem too. Have you found it how we can simulate this condition?
