Reply To: Fluent crashing with no error message when initialising simulation with new UDF’s

You are allowed to add things over a couple of posts. We only complain when it's to bump a thread!
Assuming the initialisation completes plot the material properties to make sure they're sensible. You may also find it's safer to run an iteration with fixed properties then use the UDF. The latter means all of the flow gradients etc are present in case your code uses them.
