hello, I designed a elbow 90degree, 64inch.
PSI is 150 (internal pressure).
I have done the fixtures, fixed geometry on the both ends of the elbow.
material properties is done, which is cast iron.
the information was taken from this website: http://www.starpipeproducts.com/pdf/utility/catalog/UCAT1201/flanged.pdf
mesh is good but when i run simulation for the results, it just shows this error "The Iterative Solver stopped. The solver has numerical difficulties. Model may not have adequate fixtures. No results saved"
I have tried everything but still showing this message, i don't know where i am going wrong.
Can someone please have a look at my design and see if there is any problem?
i am uploading the part.
