EID |
CHBDYE surface element identification number. No default (Integer > 0) |
PCONID |
Convection property identification number of a PCONV card. No default (Integer > 0) |
TA |
Ambient points used to specify ambient temperature. No default (Integer > 0) |
1. | The basic exchange relationship is expressed as: |
q = H * (T - TAMB)
Where, H is the free convection heat transfer coefficient specified on a MAT4 card referred by a PCONV card, T is the grid temperature, and TAMB is the ambient temperature.
2. | CONV is used with a CHBDYE card having the same EID. |
3. | In linear steady-state heat transfer analysis, ambient temperature is specified by SPC of the TA point. |
4. | This card is represented as a slave element in HyperMesh. |
