Hi.
I have a problem if you can help me. I have a Newman Boudry condition variable over time (| vr • n | = 0.1Ks = 1.8mm.h-1 for t <-6 hours and (| vr • n | = 0 for t> 6 hours) how I can write this condition in COMSOL?

Hi

The link you gave leads to a website which asks to install a software. I won't do that.
