Community contribution from Johan Roenby, DHI
IsoAdvector is a geometric Volume-of-Fluid method for advection of a sharp interface between two incompressible fluids. It works on both structured and unstructured meshes with no requirements on cell shapes. IsoAdvector is as an alternative choice for the interface compression treatment with the MULES limiter implemented in the interFoam family of solvers.
The isoAdvector concept and code was developed at DHI and was funded by a Sapere Aude postdoc grant to Johan Roenby from The Danish Council for Independent Research | Technology and Production Sciences (Grant-ID: DFF - 1337-00118B - FTP). Co-funding is also provided by the GTS grant to DHI from the Danish Agency for Science, Technology and Innovation.
The ideas behind and performance of the isoAdvector scheme is documented in:
