template<int dim, typename number >

void MeltPoolDG::MeltFrontPropagation< dim, number >::compute_solid_and_liquid_phases ( const VectorType &  level_set_as_heaviside )

private

This function determines the solid fraction for a given pair of temperature (T) and level-set-heaviside values (phi) as follows:

---

| | | | phase | solid fraction phi T |

_________	___________________________________________________________
solid	1.0 1 T <= T_solidus
	T_l - T
mushy	-------— 1 T_solidus < T < T_liquidus
	T_l - T_s
liquid	0.0 1 T >= T_liquidus
gas	0.0 0 independent
_________	___________________________________________________________

If no mushy zone is prescribed, then T_solidus = T_liquidus = T_melting.

This function returns the solid fraction from a linear interpolation between the solidus and liquidus temperatures, i.e. 0 (T>=T_liquidus) and 1 (T<=T_solidus).

private

The reinitialization constraints are modified such that they are zero in solid regions. This means, the level set field is not modified due to reinitialization in the solid regions.
