No, I haven't modeled your example, but it seems simple enough. Here's
the section from the Students' QuickField User's Guide:
3.2.5 Thermal Analysis
Thermal analysis plays an important role in design of many different
mechanical and electrical systems. Generally the quantities of
interest in thermal analysis are temperature distribution, thermal
gradients, and heat losses.
QuickField can perform linear and nonlinear thermal analysis for 2-D
and axisymmetric models. The program is based on heat conduction
equation with convection and radiation boundary conditions.
Following options are available for thermal analysis:
MATERIAL PROPERTIES: orthotropic materials with constant thermal
conductivity, isotropic temperature dependent conductivities.
LOADING SOURCES: constant and temperature dependent volume heat
densities, convective and radiative sources, Joule heat sources
imported from current flow analysis.
BOUNDARY CONDITIONS: Prescribed temperatures, boundary heat flows,
convection, radiation, and prescribed constraints for constant
POSTPROCESSING RESULTS: temperatures, thermal gradients, heat flux
densities, and total heat losses or gains on a given part.
SPECIAL FEATURES: A postprocessing calculator is available for
evaluating user defined integrals on given curves and surfaces.
Plate models with varying thicknesses can be used for thermal
analysis. The temperatures can be used for thermal stress analysis
It would be interesting to compare the results of your test with the
