2. It is not 100% clear if you followed all suggestions from Troubleshooting, 2.4.4 I get the warning "Invalid master-slave" during analysis, what is wrong? and 2.4.6 Floating point problems - Division by zero, Loss of >7 digits on the matrix diagonal, CCFEModelExc: CCPardiso solver error: zero pivot,  Warning: Sign of diagonal changed when reducing equation, Floating point exception: Multiple floating points traps, Zero or negative jacobian,  InvertA: zero determinant, CCMaterials Extended AExc: CC5ParamYield F: project_stress_on_f_division by zero, and similar?

3. If you still can not solve the issues, please follow Troubleshooting, 2.1.1 to send us your model etc.

Regards.
