When running the program it stops without a warning. Running on an other computer gives the same result.
Why and how to resolve?
After reviewing this user file it was determined that many things must be changed in their input data file:
a. All the elements on the tubes side must be on chamber 2 (nozzles T1, T2 ;elements of geometry 103, shell 102)
b. A tubesheet cannot be directly welded on an elliptical head : insert between the body flange 301 and the the elliptical head 303 a shell which has a length equal to the straight flange of the head + the height of the flange at least.
c. All the elements on the shell side must be on chamber 1 (body flange 301)
After the appropriate changes were made the model was able to run without issue.
