Hi Markus, I changed both the maximal steps(to 100000) and the error(to 10^-4) but strangely I still get the same error at the same time (around t=0.62) even though the residual is smaller than the maximal error I set.
Here's the change I did: SolverControl solver_control(100000,1e-4) Thanks for the help.
