Stress analysis: Zero, small negative element

[p282h]

Dear All:

I tried to run a sequential thermal and stress analysis by element activation technique. I have no issues running my thermal model but have trouble in mechanical model. When I run my mechanical model, the first element-set that gets activated has no convergence problem but when I activate the second element set it has the following warnings and the simulation aborts. I need some input, please help.

of the suggested limits or the triangular or tetrahedral quality
measure is bad. The elements have been identified in element set
