User Defined Pressure Boundary Condition

January 29, 2009, 16:00

Does anyone know how to make a user defined oscillating pressure inlet boundary condition in Star-CCM?

Thanks for your help.

This can be done with tables or we have to write a pice of java code using the API

Could I simply apply a user defined field function in the form of a FFT with terms of the form: A_1*cos(2*pi*freq*$Time+Phi_1) for a pressure inlet boundary condition?

I'm not sure what venkatesh is talking about, you can just create a new field function to do this then set the boundary specification to that ff
