Hi,


Anyone know how I can input a constraint in a boundary condition? I have a time variant condition (inlet flow), but I want to constraining this value.



best regards,


Gustavo

Hi

you can mdulate the value with a time dependent function, in COMSOL most entry sections can take any function, and not only scalars. But you make the model non linear like that, it will take longer to solve

Good luck
