Hi,
I am new to COMSOL, and what I encountered is about coupled PDEs. I have two coupled PDEs in one physics model in general form. One is about heat transfer (T), the other is an ODE used for the source term of the heat transfer (T). The ODE looks like du/dt=f(u,T), namely du/dt is a function of u and T.
When I ignore the T, like du/dt=f(u), COMSOL works. But it doesn't work when I consider the T. As follows.
Repeated error test failures. May have reached a singularity.
Time : 0.334945980028302
Last time step is not converged.
Thanks,
Du
