Young's modulus definition error

[zain_kalim_807]

I am trying to run an impact simulation of 2 bodies, made of custom materials. These materials (Tungsten alloy and rolled steel) are non linear. The simulation does not compute however, and when i check the solve details, it shows 4 errors. Here they are in order

- Error : Young's modulus defined on MAT1 1 is 2.7+E11

- Error : Young's modulus defined on MAT1 2 is 2.19E+11

- Error : Solver error

- Error : An error occurred while solving the model

Please provide me with some answers, i will give more information if needed

Hi @zain_kalim_807,

One possibility for the error could be a values mismatch in the nonlinear material definition. The Young's Modulus value needs to match the slope of the stress-strain curve between points 1 > 2 (which is defined by the Initial Yield Stress value).

If this doesn't resolve the issue, could you attach the dataset?

Best regards,

Yes! It worked! Thank you so much, I really appreciate it.
