Dear Sir,
I am facing a problem with a material indentation problem with Radioss. The Simulation crashes due to negative volume in the element. Please could you check as to where i am going wrong?

Praveen

Hi Praveen,
DId you check RADIOSS help?
This is mainly due to high deformation of solid meshes. Fully-integrated brick elements are especially affected by this problem which may be caused by a bad interface behavior or bad material definitions. In any case, the use of co-rotational formulation is recommended to avoid bad shear deformation response.
add /DT/BRICK/CST and check if that helps.
Hi Prakash,
tried with the /DT/BRICK/CST card, the simulation crashes with the same error! I have attached the picsf(mysimulation.jpg) along with the message! I am not sure as to what changes i need to make in the model such that I can simuate this results (Expected results.jpg)
Hi @praveen.sridhar1991
I will check and get back to you soon,
Dear Prakash,
any updates on the ALE Model?
I couldn't able to solve it myself as solid are have much better for ALE,
I am checking with Experts on the same and will get back to you soon,
Hi @roybudha
Can you try with type 18 contact instead of type 9 and check if that helps?
