Hi all,
I am running more than one model in the same file, separately. I do it because in one model I need the results of another model. I tried to refer to a solution typing, for example mod1.mf.Bx. The call works but when I solve it Comsol generates an error saying " failed to evaluate vaiarble Jacobian" of the variable mod1.mf.Bx.
What does it mean? Is there a solution? Is what I am trying to do possible in comsol?

Many Thanks,
Andrea

Hello Andrea..

I have the same problem
www.comsol.com/community/forums/acdc-module/thread/40864/

I think "but im not sure" that it has something to do with a simulation model which need the results from study one to calculate study 2..

If you see my Topic maybe you can understand what I mean

I still dont have an answer for my/ your problem so please if you found an answer post it here thanks in advance :)
