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?
I face the same problem as you. Have you found a satisfied way to calculate the force in the two-phase flow? Could you give me some advice?
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,
