Hi,

Does anyone know of a way to perform subdomain integration of a variable at each timestep so I can then export it to MATLAB? It is easy to calculate an integral at one point in time... but if I have 1,000 time steps I don't want to click each one of them individually. Anyone?

Hi
you should also be able to use the with() or at() operators in a loop in matlab to fetch your data, no ?

Have fun Comsoling

Right, but I don't know how I would perform the integral on a deformed mesh?
