I have tried to ply around with the solver settings (changing absolute and relative tolerances, max time step, and using all the advanced options) but without any success. I keep getting the error of task interrupted with the error message saying:nTHE MATRIX OF PARTIAL DERIVATIVES MAYBE SINGULARnCould you suggest another solution? I can share my files for you to investigate if that is possible.n
