strange error/message: panic54: ode3_iter=500

Good afternoon,

I'm trying to model the cyclic compression of a hyperelastic foam, given a non-linear viscosity.

*** From the experimental data, it can also be assumed that the material has the Mullins effect.

I'm trying some combinations of TNV ,Micromechanical Foam Model and Parallel Network Model models

the beginning of the solution is very safe, but then suddenly this message appears:

------------------------------------

the duration of such messages is very long... from 10,000 to 60,000 lines, after which the solution continued...

I would appreciate any help.

I have changed the Jacobian and ODE solver global variables - but it didn't help me.
