LS-DYNA: Difference between EQ.0 and LT.0

[Leibi]

Hello,

I've got a question concerning the input commandos in LS-DYNA. I'd like to use the secound damage model beneath GISSMO in *MAT_ADD_EROSION. Unfortunately I'm not able to enter the right menu because I can't enter the right value concerning the parameter IDAM. What is the difference between EQ.0 and LT.0 (EQ.0 enables the GISSMO damage model, LT.0 enables the other damage model).

Many thanks in advance!

Best regards,
Leibi

EQ.0 means equal to 0 , in your example if you set that field to 0 then it will enable GISSMO damage model.

LT.0 means less than 0, so you set the field to a negative integer the corresponding damage model will be activated. Check the lsdyna manual for which model corresponds to which integer.
