hiŁ¬
1. import your mesh in Fluent . 2. in the object tree ,double-click models>muliphae-off. 3. choose mixture and number of eulerian phase is set to 2 in the dialog box. Okay,good luck ! |

Ok! But if i set phase: air for air intlet and respectly for water and mixture for other parts of my geometry, whith k-e models for turbolence the programm diverges at 10-15 th step.. How it s wrong?
Thanks for your time! |

Ok tell me all options you wanna see.
I set: Models->MultiPhase: Mixture (2 Eulerian..) Models-> Viscous Model: k-epsilon (2 equations) For boundary condition all set to wall except for: water intlet (velocity intlet), air intlet (pressure intlet) and outlet (pressure outlet) but if i set in the boundary condition pannel a different option in the phase menu ex: phase 1 (air) instead of mixture most option don't appear in the edit menu: http://www.freeimagehosting.net/73gq5 |
