QVOL

Volume Heat Addition

Description: Defines a rate of volumetric heat addition in a conduction element.

Format:

Example:

Alternate Format and Example:

Field Definition Type Default
SID Load set identification. Integer > 0 Required
QVOL Power input per unit volume produced by a heat conduction element. Real Required
EIDi Element identification number(s). Integer > 0; EID2 > EID1 Required

Remarks:

  1. QVOL entries must be selected with the Case Control command LOAD = SID in order to be used in steady state heat transfer analysis.
  2. EIDi references material properties (MAT4 and MAT5) that include HGEN, the element material property for heat generation, which may be temperature-dependent. If HGEN is temperature-dependent, it is based on the average element temperature.
  3. The total power into an element is given by the equation:

    Pin = Volume * HGEN * QVOL

  4. At least one EID must be present on each QVOL entry.
  5. If the alternate form is used, all elements EID1 through EID2 that are not compatible or do not exist will be skipped.
  6. Elements must not be specified more than once.
  7. All elements directly referenced must exist.
  8. The continuation entry is optional.
