Composition PDF causing crushes
 

Hello

I was lately trying to get through FLUENT for a 3D simulation of a reactive system using the Composition PDF transport method and the simulation just simply fails. I know 2D simulation is recommended but is that the only option laid out?

I also wanted to add a species mixture model, which has components that are not listed in the database. Is there any way to do that? I'm kind of desperate for answers.

Thanks
