Nonlinear iteration is not converging with step size reduced to hmin (3.22191e-17) at time 0.00906886. Try reducing the minimum step size and/or relax the relative error tolerance
I have been trying to simulate heat transfer problem in Comsol 5.5 for long time but it always throw an error stating: "Failed to find a solution. Maximum number of Newton iterations...

Hi, I have modelled a three-span arch bridge with soil fill over along with pedestals. The FE modelling is done in LUSAS with HX8M solid elements (i.e. 3D solid modelling). The non-linearity is...
