I'm running a two-way FSI analysis in ANSYS Fluent. My UDF worked fine when I tested it in pure CFD analysis, but when I use it in the FSI simulation, it doesn't run, and I get this error:

Can you help me figure out what's causing this and how to fix it?

Hello Farah,

are you sure this is because of the UDF? Does your analysis run if you deactivate it?
