Convergence error (UMAT) - Linear Viscoelastic material

Hello Jorgen and all,

I have developed a user material (UMAT) for finite strain linear viscoelastic material. There is no convergence issue related to single C3D8H element, however after mesh refinement (more elements - e.g. 125 ) it does not converge with static and dynamic, implicit solver.

How could i remove this error ? Please help.

Regards
