Hi Amit,
As per as I understand from the images you shared, it looks like there is some issue with the contacts. I have some suggestions which you can try.
- If you have contact between a shell and a solid body, so did you consider the shell thickness effect?
- Please check the initial contact information properly and see if it is correct or not. You can check the status, penetration, or gap. If you find some things wrong with contact then make changes accordingly.
- For the frictional contacts which have some gaps, try using contact stabilization damping with the 'Add offset, ramped effect' interface treatment.
- Make sure that you have large deformation ON and that you are using enough number of substeps.
- If a large friction coefficient is defined (>0.2) consider using an unsymmetric solver.
Please check the solve.out file properly for the warnings and error messages for finding the exact issue. You can also use contact trackers and Newton Raphson residuals to find the problematic region.
Thank you,
Akshay Maniyar
