Default AMG Divergence with Energy Eq
Posts: n/a
Okay for some reason today, I'm encountering the AMG divergance/floating point exception errors when attempting to run a few simulations on venturi tubes.

I'm able to run a venturi tube model with the energy equation enabled without a problem. I went into gambit and designed a similar model but with different dimensions. I meshed it the same way, set everything up in fluent the same way, except now if the energy equation is enabled it crashes. This happened with three different models that I made today, but the models that I made yesterday run without a problem. Aside from the new models being larger than the old ones (12" diameter instead of 8") there is really no difference. Anyone have any ideas why this would be happening?
