Hello,
I m starting using Radioss Implicit solution and I have convergence issue on simple problem. It is a plate in flexion (P14_SOLID) clamped at one extremity. An infinite rigid tool (P1_SHELL with RBODY) with imposed displacement at the other extremity bend the plate.
There is a counter form under the plate also infinitely rigid.
Contacts are surface to surface (TYPE19).
The plate is in aluminium (M2_PLAS_JOHNS) with failure model (JOHNSON).
The tools is in steel (M1_ELAST)
I took the example on RD-E: 4200 Rubber Ring: Crush and Slide for radioss engine parameters but i don't understrand why the time step decrease infinitely and simulation crash.
I think that i make a basic mistake but i don't knwo where, can you please help me to debug my model ?
Thank you very much,
Best regards,
