impact on wheel
Altair EmployeeHello, I am trying to make an analysis of wheel impact on the floor. During the analysis i faced zero volume tetra elements. Masses of the materials were upscaled to run the analysis faster (to be sure it works before letting it run for 9 hours). In my opinion small value in tetra collapse doesn't effect. I attached the model. Thanks in advance.
In addition, I searched through forum for the solution and didn't find anything helpful. (added dt/brick/cts, distance in rigid wall, istmr =2, increased thickness to shell elements, increased Gapmin )

update to the model:
1) changed the direction of normals in contact.
2) re meshed the tire to quad elements.
3) changed surface of impact to rigid wall
4) redefined contacts with type 7, slave =GRNOD, master =contact surf.
5) checked for any penetration and intersection in the model.
still getting warnings in interface and zero volume termination.
i think i am still defining small strain formulation wrong. please help me find the issue.
i attached all latest files.

can you please check the boundary conditions and loading provided?. Somewhere a violation is there and please clear it to avoid incompatible kinematic conditions which is an undesired warning.
please find the model with all penetrations cleared.
