The Steady State Thermal Analysis Program (STEADY) provides the thermal
designer with a quick and convenient method for calculating heat loads
and temperatures. STEADY can be used on small nodal networks for conceptual
or preliminary thermal design and analysis. STEADY will accept up to
20 nodes of fixed or variable temperature, with constant or temperaturedependent
thermal conductivities, and any set of consistent units.
In a steady state thermal network, the heat balance on each variable
temperature node must sum to zero. The general heat transfer equations are
solved with a Newton-Raphson technique and refined by a fourth order quartic
solution.
Input data includes the number of nodes, number of boundary
nodes, the fixed temperatures at all boundary nodes, initial temperature
guesses for variable nodes, impressed heat loads, conduction and radiation
coefficients, and control parameters such as convergence criteria, maximum
iterations, and damping factors.
The output is stored in a print file and
tabulates final temperatures and heat flows for all nodes. STEADY is menu
driven and allows the user to save files for future modification.
STEADY carries the NASA case number NPO-17179. It was originally released as part of the NASA COSMIC collection.
