The specific heat matrix for this element is simply:
(13–142) |
C^{o} is defined as:
(13–143) |
where:
ρ = density (input as DENS on MP command) |
C_{p} = specific heat (input as C on MP command) |
vol = volume (input as CON1 on R command) |
C_{a} = capacitance (input as CON1 on R command) |
The heat generation load vector is:
(13–144) |
where:

A_{1}, A_{2}, etc. = constants (input as A1, A2, etc. on R command) |
T_{unif} = uniform temperature (input on BFUNIF command) |
= temperature from previous iteration |
T_{o} = offset temperature (input on TOFFST command) |
