Heat Sources

The most basic type of source is a constant source. A constant source does not vary with time or temperature. Its format is shown below.; ND, Q $ (basic format) where:

ND is the node where the source (heat) is applied, (Integer)
Q is the applied source (heat), (Floating Point)

       117,   150.000      $ hot MIC

In this example the Hot Instrument Cavity, node 117, has 150 mW associated with it.

Source Input Format

In addition to constant heat sources, TAK 2000 can model sources that vary with time (smoothly), vary with time as a cyclic function (smoothly), vary with time as a step function, or vary with temperature.

The GEN input option allows the user to generate a group constant sources. Variable sources can be modeled by using the STF, SIV, TVS, PER, and FLX options.

A node may have multiple sources applied to it. In this situation all sources are summed together.
