PAFLUID
Bulk Data Entry Defines the properties of a 1D CAFLUID heat flow element.
The 1D CAFLUID element can conduct heat and transmit fluid between its two primary nodes. Heat flow is due to conduction within the fluid and mass transport of the fluid.

Comments
- The 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 mass flow rate can be defined via the W field on the referenced PAFLUID entry.
- The hydraulic diameter of flow cross-section can be defined via the D field on the referenced PAFLUID entry.
- The fluid thermal material properties are defined via the MID field on PAFLUID entry that references a MAT4 entry.
