[Commercial meshers] No Convergence with Fluent

arman2_civil · April 12, 2009, 16:16

Hi Friends
I am modeling a large natural reservoir with fluent,First I used gambit and built the geomery and mesh.My mesh spacing is 20m size.it is tri pave mesh for faces and tgrid for my volume.I have only 3000 skewed elements and the meshing is now successfull.I have two inflows and an outflow.Now I am using fluent to find my steady state velocities after a flooding.I used all of the boundary conditions as walls,symetry for surfsce,velocity inlet,pressure outlet or outflow and others for my reservoir.But no one can model a real region because with no one my fluent can converge and the continuity equation allways have high residuals and cant converge.I dont know how should I determine my velocities.If anyone knows about the converging method in such a same case please help me,
best regards,
Arman.
