This UDF works perfectly in ANSYS Fluent alone and delivers correct results. However, as soon as I activate the coupling with Rocky DEM, a problem occurs: The simulation aborts with an error message.&lt;br&gt;As this simulation is of great importance for my master thesis, I would be very grateful if you could help me to solve this problem.
