hello all i have a question about VOF model. i'm trying to slove some VOF problem. but it is quite hard then my co-worker wants to solve this using CFD-ACE (we are using FLUENT right now) he said CFD-ACE is better for solving VOF model. but i can not sure about that. i can't find any good reason for that. if any of you know about this, please help me!

what type of problem you need to solve with VOF?

ah,, some kind of siphon for washing machine.

sorry i have no experience with this subject hope you find somebody else from cfd-online help you with it.

If you have Fluent and are already familiar with it, I don't see why you wouldn't use it. I use Fluent for a free surface swirling/mixing application using VOF and it does a great job--the NITA solver is especially helpful as it can give you a significant speed increase. That said, I am not familiar with CFD-ACE but from the description on their site it appears that it does not have as many options for VOF flow. Hope this is helpful. -KW

hi,

(VOF) module in ACE+ enables the simulation of a mixture of two immiscible fluids, including the effects of surface tension.
and it is very well compatible with Heat Transfer, Stress, Deformation, Magnetic, and Chemistry/Biochemistry modules.
