Comments

  1. EID# has material properties (MAT4/MAT5) that include HGEN, the scale factor for volumetric heat generation. This association is made through the element EID.
    QVOL provides the constant volumetric heat generation rate. QVOL is positive for heat generation. For steady-state analysis, the total power into an element is:(1)
    P in = volume * HGEN * QVOL

    Where, HGEN is the scale factor from the MAT4 and MAT5 data.

  2. For use in steady-state analysis, the load set is selected with the Case Control command LOAD=SID.
  3. This card is represented as a flux load in HyperMesh.
