Boundary Heat Flux Load for CHBDYj Elements

Description: Defines a uniform heat flux into CHBDYj (CHBDYG, CHBDYP) elements.

Format:

Example:

Alternate Format and Example:

Field Definition Type Default
SID Load set identification number. Integer > 0 Required
Q0 Heat flux into element. Real Required
EIDi CHBDYj element identification number(s). Integer > 0; EID2 > EID1 Required

Remarks:

  1. QBDY1 entries must be selected with the Case Control command LOAD = SID in order to be used in steady state heat transfer analysis.
  2. The total power into an element is given by the equation:

    Pin = (Effective area) * Q0

  3. Q0 is positive for heat input.
  4. At least one EID must be present on each QBDY1 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. Continuations are not allowed.
