| Specific Heat Matrix and Heat Generation Load Vector | None | None |
The specific heat matrix for this element is simply:
 | (13–142) |
Co is defined as:
 | (13–143) |
where:
| ρ = density (input as DENS on MP command) |
| Cp = specific heat (input as C on MP command) |
| vol = volume (input as CON1 on R command) |
| Ca = capacitance (input as CON1 on R command) |
The heat generation load vector is:
 | (13–144) |
where:
 |
| QR = heat rate (input as QRATE on MP command) |
| A1, A2, etc. = constants (input as A1, A2, etc. on R command) |
|
|
| Tunif = uniform temperature (input on BFUNIF command) |
 = temperature from previous
iteration |
| To = offset temperature (input on TOFFST command) |
