Hi All

I want to coupled three things, thermal +structural + electrical problems and solve them all together not separately. Any idea how to do it in COMSOL. I ave attached the coupled equations.



Thanks,

Hi,

There are basically two approaches that you could use:

1. Build the model with one Piezoelectric Devices interface and one Heat Transfer in Solids interface. Then add the missing coupling terms using weak contributions. Maybe not all couplings are significant?

or

2. Create the whole fully coupled physics using the Physics builder.

Regards,
Henrik
