I was doing the model for auxetic yarns which have two types of materials, the hyperelastic and the elastic. I have tried different mesh size but it was still not converged. In addition, I have also tried some settings as follow:
1. turn on Nlgeom for step
2. change the minimum increment size
3. use boundary conditions instead of load
Could you please help me to solve this problem?
"too many attempts made for this increment" is just a generic error message meaning that your solution is non-converging. If you include plasticity (as you do), it might mean that yield is making your model unstable. Reasons can be high loads, or low material strength
and also, remove contact interaction. Then try to run your job. If same error happened then again apply your contact properties and no check for mesh. Use uniform mesh size and same element type. And also, make sure that properties that you are giving are correct
