How to choose the buoyancy model?
 

I want to simualte the flow field of a gymnasium and need to add the gravitational forces. Then I select the DENSITY DIFFERENCE as the buoyancy model. At the same time I choose the domain material as AIR USING IDEAL GAS LAW. When I press RUN /EARTH,the PHOENICS exit automatically. Can anybody help me? What's the difference between these buoyancy model ? Thank you.

From my PHOENICS experience, the error that you r ecountering can be related to a number of things, email me back your q1 file and I will send you my comments back with the corrected Q1 file. I used to work for CHAM, and would be very to help PHOENICS users

Kind regards Salam

I think that you can see the result file to see what you should to correct. I guess that you should store density.
