Hi everyone,

I'm using solids4foam to simulate a cylinder rotating in a fluid domain. I'm not very clear about the parameters defined in constant/dynamicMeshDict. I list as follows:

diffusivity quadratic inverseDistance 1( cylinder );
nNonOrthogonalCorrectors 2;

initialRotationOrigin (0 0 0);
rotationAxis (0 1 0);
rotationAmplitude 0.5;
rotationFrequency 0.1;

So how does solids4foam define rotation, how to get the angular velocity from rotationAmplitude and rotationFrequency?

And what does the diffusivity quadratic inverseDistance and nNonOrthogonalCorrectors mean?

I'm confused . These parameters influence much in my simulation according to the output file.

angular velocity, rotation, rotation amplitude, solids4foam
