TEMPO
Thermal simulation determines either steady state (final temperature) or transient temperature rise due to given heat sources. The sources can either be specified by the user, or can be due to electromagnetic heating computed with other Opera-3d analysis modules, and imported to the thermal simulation.
The thermal conductivity tensor, density, thermal capacity and heat source density can be temperature dependent (leading to non-linear behaviour) and may also be specified as a function of spatial position.
Boundary conditions are primarily used to specify the coupling of the thermal system to its surroundings. A range of conditions are available including a general non-linear transfer condition that can be used to model radiation.
Features include: Full 3D modelling Automatic Mesh Generation Non linear materials Interfaces to CAD/CAM Various boundary conditions including:
fixed temperature heat flux heat-transfer to fixed temperature medium radiation general non-linear transfer condition Display of temperature, temperature gradient and heat flux distribution Import of heat sources from electromagnetic analysis - see Elektra and Scala

Thermal modelling is also used in multi-physics simulation, by coupling with other Opera-3d modules, when temperature dependent electromagnetic properties are significant.
