I meet some problems when i write the UDF code for a time dependent pressure, which will added as the boundary conditions of outlet. I only have a table of pressure values with times, the function should work like : read the values of P from the file P.text each time step and distribute that on the outlet (outlet bc is varing with time). i try to use DEFINE_PROFILE and CURRENT_TIME macro. but there is not equation of pressure with time, only have fixed table. Anyone know how to add a profile to UDF will be appreciated.
