text: Please provide more information to suggest anything that might help in troubleshooting. The provided information is not sufficient. May be you can post a snap of model setup and stress/displacement plot.
  -What is the element type?
  -Is the element quality good that is whether max aspect ratio is less than 10 and other quality parameters within range?
  -What is analysis type? static/transient, structural/thermal and/or implicit/explicit?
  -How are you defining load step increments? What are the load magnitudes?
  -How the stress/displacement plot of last converged step looks?( Is is reasonable/realistic as expected?)
