Fluent GUI automatically improving mesh quality on startup
 

For a certain workbench project, every time I open up Fluent it automatically starts reordering my mesh and improving poor quality cells. The whole process can take up to 30 minutes, during which the GUI does not respond to user input. It is very annoying. I must have changed some setting by accident, because other projects do not do this. How can I stop Fluent from doing this? Thanks.
