[Swirl]

Hello everyone,

I am currently trying to validate a setup using the interIsoFoam solver in a stationary bubble testcase. With my current setup I strongly underestimate the pressure jump across the bubble/ drop.

I found the setup file of the benchmarks performed by one of the isoAdvector authors (https://wiki.openfoam.com/The_statio...y_Lionel_Gamet) which produces the exact analytical result when using the plic-RDF reconstruction scheme.

I noticed, that the Allrun_sensitivity script calls for a solver "interFlow" instead of interIsoFoam and adds the lines

surfaceForces
{
  sigma ${sigma};
  curvatureModel RDF;
  accelerationModel gravity;
  gravity (0 0 0);
  deltaFunctionModel alphaCSF;
}

to the constant/transportProperties dictionary. However, adding these lines makes no changes for my setup and i could not find any reference to the "interFlow" solver or any of the above keywords in the source code.

Does anyone have more information, about how I can set the curvature model to RDF and which OF-version is necessary for that? I currently use v2112.

Thank you very much for any help. I appreciate any hints!
