Hi, I’m trying to solve a flow problem, and I simply call the solve function to solve it as non-linear problem solve(F == 0, u, bcs, J, params) The problem is my formulation is not stable, sometimes I get non-convergence. But it is fine, I just want to know if the solver did not get converge, so t…

Is there a way to get a signal for non-converging solve() call

You can do this by creating a NewtonSolver see here.

Cf. also here.
