Sliding mesh problem
I'm currently performing a fan simulation in Fluent. I get a warning that non-positive volumes exsist when running unsteady with sliding mesh, and the simulation crashes. However, if I specify a MRF region instead of sliding mesh the simulation completes without warnings. What could be the reason for this and how to avoid it?
Re: Sliding mesh problem
That means your rotating volume is connected to your stationary volume. Both these volumes need to be disconnected (in GAMBIT) before sliding mesh can take place. What you can do is to convert your MRF case to a sliding mesh case automatically. This is done via TUI:
It will then prompt you to input the ID number for your rotating domain.
You should be able to do sliding mesh simulation without any problems now.
Hope that helps.
