The following statement is integrated in the UDF in the description of a phase volume fraction in the solution process. It performed at the beginning of the solution process. This function sets up a central spherical body in 0.5, 0.5, 0.5, with a radius of 0.25. The second phase volume fraction of a supplementary explanation to the spherical body unit, but the second phase in the other unit in the volume fraction of 0
