Preparing mathematical model and solving mathematical model stuck
 

Hey,

So I am running an analysis on a blade and disc geometry. The mesh has been generated and I am now solving for a solution. The Workbench Solution Status keeps going from preparing the mathematical model to solving the mathematical then back. The overall progress bar doesn't seem to be progressing. I'd just like to confirm if this is a regular issue and I should just wait patiently for full analysis to run, or if there is some form is issue here I am not picking up on?

Hope you can help.

has it run in last 6 days?
