Comments

  1. 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).
  2. MAT1EC is supported for all electrical elements.
  3. JHFRAC controls the percentage of power transferred to Joule heating losses. By default, all power generated by the material is transferred as Joule heating.
