Element erosion is not observed
I tried a drop test with a robot.
I am using solid elements with the LAW36 material model, and I have added the BIQUAD failure model. However, I don't see any element erosion.
Can you help me in this issue?

Altair EmployeeHi,
Please ensure that all material properties related to element deletion are defined. If certain properties, such as EPS_p_max and Epsilon_F, are not specified, the elements will not be deleted.
Additionally, on the output cards, request Plastic Strain (H3D/ELEM/EPSP) and verify if the plastic strain reaches the value set in the material property. If it does not, the elements will remain intact.
Lastly, check the interface TYPE2 settings. Depending on the Idel defined, elements may not be deleted.
Best regards,

The parts of the robot are connected with a tie contact (TYPE 2)
