deepblue17 Member Oliver Borm Join Date: Mar 2009 Posts: 60 Rep Power: 17	Hello, there is an additional term in the momentum equation in the MRFSimpleFoam solver in version 1.6 compared to version 1.5: - fvm::Sp(fvc::div(phi), U) Has anybody an idea, why this term was added and where it comes from? For me the version in 1.5 looks better without this term, if one compares both mathematical backgrounds of the MRF theory ( http://openfoamwiki.net/index.php/Se...RF_development and http://openfoamwiki.net/index.php/Si...ry_MRF_Library ).
