I'm trying to understand time dependent study in coupled mode using the above two physics modules. I'm trying to use an existing tutorial steps and extend this to time dependent study. As per the tutorial, J0 - current density is a required input parameter and the study carried out doesn't have any changing magnetic field. However, I want an ac magnetic field, and by varying J0, I get to vary magnetic field and am interested in taking a look at how this will affect magenetostriction. I want to make J0 a time dependent variable and for this I have defined another variable J1 as J0*t. When I try to run compute, it gives me an error saying
Failed to find consistent initial values.
Last time step is not converged.
I'm trying to extend what is given here - www.comsol.com/model/nonlinear-magnetostrictive-transducer-6063
Any pointers as to what I'm overlooking would be appreciated. I've just started playing around with Comsol and would appreciate some inputs.
Thanks,
Varun
