Syntax

Tensor Thermal Conductivity [{of} SpeciesName] = Constant [Xx = xx | Xy = xy | Xz = xz | Yx = yx | Yy = yy | Yz = yz | Zx = zx | Zy = zy | Zz = zz | T11 = t11 | T12 = t12 | T13 = t13 | T21 = t21 | T22 = t22 | T23 = t23 | T31 = t31 | T32 = t32 | T33 = t33]

Scope

Aria Material

Summary

Constant tensor value for the thermal conductivity

Description

Either

$k = \begin{bmatrix} &\text{XX} &\text{XY} &\text{XZ} \\ &\text{YX} &\text{YY} &\text{YZ} \\ &\text{ZX} &\text{ZY} &\text{ZZ} \end{bmatrix}$

or

$k = \begin{bmatrix} &T_{11} &T_{12} &T_{13} \\ &T_{21} &T_{22} &T_{23} \\ &T_{31} &T_{32} &T_{33} \end{bmatrix}$

can be used. Any unspecified components of the tensor default to 0.
