Field	Contents	SI Unit Example
`MID`	Unique material identification number. No default (Integer > 0)
`RHOij`	Electrical resistivity along each direction. No default (Real > 0.0)
`JHFRAC`	Fraction of Joule losses over total power generated in the material. 3 1.0 (Default) Blank 0.0 ≤ Real ≤ 1.0

The material identification number may be shared with structural material property definitions (MAT1, MAT2, MAT8, MAT9, or MGASK) or thermal material property definitions (MAT4, MAT5), but must be unique with respect to other electrical material property definitions (MAT1EC or MAT2EC).
The electrical conductivity matrix has the following form:
$σ = [\begin{matrix} \frac{1}{ρ_{x x}} & 0 & 0 \\ 0 & \frac{1}{ρ_{y y}} & 0 \\ 0 & 0 & \frac{1}{ρ_{z z}} \end{matrix}]$
JHFRAC controls the percentage of power transferred to Joule heating losses. By default, all power generated by the material is transferred as Joule heating.
