Level-set VOF results problems
 

Hello!

I am trying to model flow front of a liquid-gas flow. In the case, with a polymer and an air.

To do that i am using VOF model in fluent, who give a pretty good flow front definition, according to the experimental.

I al trying to use level-set, but this seems more instable than VOF.

I am curious, since the couple Level-Set and VOF should give better results, right?

Thanks for your's ideias
