Hello everybody I'm currently trying to design a heat transfer with electric flow in Comsol. and I could not solve this problem for a few days. The problem is that every time I get an error saying: Feature: Stationary Solver 1 (sol1 / s1) Failed to find a solution. Maximum number of newton iterations reached. There is an error message from the linear solver. The relative error (14) is greater than the relative tolerance. Returned solution is not converged. Not all parameter steps returned.
I also found some possible solutions on the internet, but they do not work for me. The possibilities were eg: change the "Maximum number of iterations" to 1000 under the Fully Coupled . or change Relative tolerance to a number less than 1. eg 0.1.
Thanks for the help.
