Hi Pals
I wanna set an expression for inlet boundary condition.
that's it:
u=Umax(t)[1-r^2/R^2]

No problem so far!
but I want it to pick up the Umax(t) from the specified cyclic curve in every timestep!
How can I do that?

thanks alot

If you know the Umax function then write it as a CEL expression. Otherwise use an interpolation function to define the Umax expression.

Thank you soooo much
I appreciate your help.
I think I should use an interpolation function.

Best regards
