Please use SimLab to create a new PEEC project (not possible to import an existing Flux PEEC project).

/!\ Documentation updates are in progress – some mentions of 3D may still appear.

Thermal region: about

What we can simulate?

With regions it is possible to describe:

  • material media such as:

    • conducting material media (thermal conductivity k) with possibly a heat source (imposed value of thermal flux)

  • boundary conditions of the following types:
    • heat transfer (on faces)
    • imposed temperature (on faces or lines)
    • insulated face (adiabatic boundary)

3D specificity

In 3D problems, it is also possible to describe thin conducting regions with thermal exchanges on both faces.
