Hi all,
I am trying to simulate the bipolar charge transport model in an underground power cable. In comsol, I used electrostatics, heat transfer in solids, and transport of diluted species. when I run the simulation, comsol give me an error of:
Repeated error test failures. May have reached a singularity.
Temps: 0.0010625366899411094.
Last time step is not converged.
Hi, could you give us more information on what you're trying to do and how you set up your studies?
Assuming that your boundary conditions and physics setup are correct, this seems to be more like an issue with how you set up your meshing and studies. Try looking at this thread here: https://www.comsol.com/forum/thread/38145/singularity-error
Coarse meshing is often an issue with simulations of very large gradients.
Let me know how it goes or if you have solved the problem.
