7.6.18.12.16. Phase_Average

Syntax: Thermal Conductivity [{of} SpeciesName] = Phase_Average ([Subindex_A = subindex_a] | [Subindex_B = subindex_b])
Scope: Aria Material
Summary: Level set phase averaged thermal conductivity.
Description: $k = (1 - H(\phi)) k_A + H(\phi) k_B$

where $H(\phi)$ is the heaviside function evaluated at the level-set variable $\phi$ , $k_A$ is the thermal conductivity in phase A, and $k_B$ is the thermal conductivity in phase B.
