Auto BC change
 

Hello. I'm trying to model valve opening/closing by changing boundary conditions (wall to interior and vice versa). In Fluent 6.2 it is possible to do by selecting Define-Dynamic Mesh-Events. But BC change available only at certain time. I need to change BC according to pressure difference at both sides of the valve. How this can be done?

Thank you for help. Ilia Skryabine
