[FEA error] The iterative solver stopped.

Question asked by Cl So on May 24, 2018

Hi! I just finished a simple internal flow simulation with my pipe.

And I would like to do a pipe stress analysis due to the flow, therefore I exported the flow simulation result into the FEA study.

However, I have encountered a lot of problems, e.g. meshing problem (interference problem...), and I have tried very hard to solve it with meshing control.

But after the meshing is ready, when I run the FEA study, it shows this message when it is about 50%.

 

" The iterative Solver stopped.

Numerical difficulties. (Preconditioning failed)

Please check model boundary conditions.

No results saved."

 

I have tried to check my boundary conditions in flow simulation, but I couldn't find anything I can do.

Please help if there are any ways I can solve this FEA study for my pipe stress analysis.

MANY THANKS!!
