Hello,

Are the residual stresses that you import from Moldex3D in the correct unit system? Make sure you are using a consistent unit system:

https://lsdyna.ansys.com/consistent-units/

You will find more information about importing data from Moldex3D in LSPP at the end of *MAT_303 in the LS-DYNA Materials Manual.

Note that "the mapped data will be exported as material history state variables in the initial stress keyword cards *INITIAL_STRESS_SHELL or *INITIAL_STRESS_SOLID.".

 

Let me know how it goes.

 

Reno.
