Hi all foamers! I'm studying interFoam in deep and I'm trying to see what is the foundation of interfaceCompression divergence scheme. As is indicated in code description it isn't a TVD/NVD derived scheme although it is writen in consistent way with all other limiters.
1. What are the hypothesis assumed to derive this scheme? 2. Anybody has something written about this?, at least some notes. 3. Why not to use another divergence schemes? Regards.

I'm interested in interfaceCompression scheme too

Hi, it seems that the blending factor is chosen such that upwind is used when the solutions reaches the extrema. The blending is not based on TVD/NDV since the nonlinear term which is being limited is not a normal flux based convection term. Here is a similar approach
http://imajna.oxfordjournals.org/con...1/116.abstract the interfaceCompression scheme gives a to use in the TVD HRS framework implemented in FOAM. http://openfoamwiki.net/index.php/Op...VD_formulation Regards.
