Hello everyone

I am trying to model a steel-composite adhesive joint under bending conditions.

every time I run the same model and after getting normal termination, I check the results and the rcforce of the results are different every time, also there are some overlaps but overall the results are different and not the same. for example, the picture below shows the results of two separate runs.

I am using mat 59 to model composite and balsa core and mat 24 to model the steel part. also, mat 138 for modeling the adhesive.

I would appreciate your help.

best regards.
