Hi, i'm using the pde mode in comsol 3.5 and i'm trying to run a time dependent analysis where at each time step one of the terms contained in my equations must be update by using the solution at the previous time step. I can't figure out how that's should be done even using comsol script...and in the comsol user guide there is nothing about it. Does someone have some idea?
Best regards

Hi,

I am actually having exactly the same issue, and just as much trouble finding a solution for it.

If anybody has figured this out the help would be much appreciated :).
