Is Geo reconstruct scheme available for only 2 phases?
 
Hi
Under (VOF) multiphase model in Fluent, can't we use geometric reconstruction scheme (for volume fraction) for more than two phases?
I tried it, but it was not available for 3 phases. Instead, I used Modified HRIC scheme.
thanks in advance.

Agree, I faced the same problem when I tried 3-phase flow with geo-reconstruction scheme. When the two sceondary phases merge, the contours of mixed phases are in a disorder, the interphase has singularities.

The Geometric Reconstruction Scheme
 
The Geometric Reconstruction Scheme
In the geometric reconstruction approach, the standard interpolation schemes that are used in FLUENT are used to obtain the face fluxes whenever a cell is completely filled with one phase or another.
when the cell is near the interface between two phases, the geometric reconstruction scheme is used.
