Hello i am solving a thermal stress problem
with a viscoplastic materail model
i defined all the bc s
but i am getting the error for viscoplastic variables as
Undefined value found.
- Detail: Undefined value found in the stiffness matrix.
There are 1217 equations giving NaN/Inf in the matrix rows for the variable mod1.ex_v
at coordinates: (0,0), (0,0.02), (0,0.04), (0.0129312,0.0335295), (0.0258624,0.0270591), ...
There are 1217 equations giving NaN/Inf in the matrix rows for the variable mod1.exy_v

There are 1217 equations giving NaN/Inf in the matrix rows for the variable mod1.ez_v
at coordinates: (0,0), (0,0.02), (0,0.04), (0.0129312,0.0335295), (0.0258624,0.0270591), ...
and similarly for the degrees of freedom, NaN/Inf in the matrix columns
i am attachinh the model..can anyone suggest on this please
Many thanks
