Definition
| Field | Contents | SI Unit Example |
|---|---|---|
| ID | Forced convection interface
identification number. No default (Integer > 0) |
|
| PID | Identification number of a
PCONV property entry. No default (Integer > 0) |
|
| SSID | Secondary entry identification
number. This should refer to a GRID SET consisting of
CAFLUID grids. No default (Integer > 0) |
|
| MSID | Main entry identification number.
This should refer to either a SURF entry or
an ELEMENT SET that identifies the convection surface on which
the CHBDYE surface elements and
CONV entries are to be generated. No default (Integer > 0) |
|
| NODE | Controls how the convection area is
applied to the corresponding CAFLUID grids.
That is, the TA grid on the
CONV entry depends on this
NODE option.
Note: Convection area of a surface segment is the surface
area associated with a convection element (3D element
face belonging to the surface, or 2D shell element
area).

Comments
- The presence of the CACONV Bulk Data referring to a PCONV entry leads to automatic generation of CONV and CHBDYE Bulk Data Entries.
- CAFLUID element represents 1D elements which can conduct heat and transmit fluid through mass flow. The PID field points to a PAFLUID Bulk Data that determines the element property.
- The internally generated CONV entries and CHBDYE elements along with the CAFLUID elements can be output to dedicated *_CAFLUID.fem and *_CONV.fem files when PARAM, CACONV, YES is added to the model.
