ρ (SI unit: kg/m3) is the alloy’s density.
|
•
|
Cp (SI unit: J/(kg·K)) is the alloy’s heat capacity at constant pressure.
|
•
|
k (SI unit: W/(m·K)) is the alloy’s thermal conductivity (a scalar or a tensor if the thermal conductivity is anisotropic).
|
•
|
u (SI unit: m/s) is the velocity field defined by the Translational Motion subnode when parts of the model are moving in the material frame.
|
•
|
Q (SI unit: W/m3) is the heat source (or sink). Add one or several heat sources as separate physics features. See Heat Source node and Thermoelastic Damping subnode for example.

This model input does not override the Reference temperature Tref set in the Physical Model section of the physics interface, and that is used to evaluate the reference enthalpy, and a reference density for incompressible nonisothermal flows.

Volume average (default), which computes the effective conductivity of the alloy as the weighted arithmetic mean of austenite and martensite conductivities:
|
•
|
Reciprocal average, which computes the effective conductivity of the alloy as the weighted harmonic mean of austenite and martensite conductivities:
|
•
|
Power law, which computes the effective conductivity of the alloy as the weighted geometric mean of austenite and martensite conductivities:
