andrewpm1993 is on a distinguished road
Hi, I'm trying to simulate a simple 2D two stroke diesel engine. I receive the following error "Error: Divergence detected in AMG solver: temperature
Error Object: #f" after Fluent has executed an in-cylinder event to create a sliding interface (open a valve, which is what tutorials and the user guide describe how it is done). The simulation has already opened and closed the valve earlier on (using create a sliding interface and delete a sliding interface). So I'm not sure where this error comes from, any help appreciated as I have been stuck on this for a few weeks and have fallen behind on my dissertation
