CLSVOF- theory help
I'm using the Fluent Release 19.0 Academic version and was wondering for the theory guide help. I scrolled the theory for the CLSVOF model, but wasn't able to find out the "coupling" relationship of VOF marker function with level set function; before the re-initialization of level set function takes place. I know there's a functional dependency based on the Heaviside functional formation and in literature people have used different values of the Heaviside function. Also, the properties (like density and viscosity) are being calculated from the level set function. However I'm unable to find the exact equation of the functional dependence of the properties on level set function. Also it would be helpful if I'm provided with the basic algorithm for the same. Note that I'm not using any UDF, just the in-built coupling of level set with VOF model.
