forces in interFoam
I have some problems to get forces with standard library libforces.so for interFoam solver. I found one article from workshop, in which author made own library (libhullForce.so)(http://www.openfoamworkshop.org/6th_...m/training.htm) to calculate forces in two-phase liquid. I took his case with BC, controlDict, fvSchemes and fvSolution and changed only geometry. But result that i got is not correct. Forces are greater that in experimet about 5-8 times. I saw my controlDict and found that in below entry
CofR (0 0 0);
there is only one density - rhoInf equals to 1000. Can libforces.so calculate forces only for monophase liquids? I use openFoam 2.0.0. Is my guess true? How is it possible to get forces components manually?

Currently you are setting the rho equal to rhoInf for all force calcs. Use "rhoName rho;" since this is the scalar field that varies in space with alpha.
Hope this helps,
