How Do I Set a Heat Simulation?

The steps to set up a heat simulation are very similar to those for an FDTD simulation:

• Create the geometry
  The Scene object hosts the simulation geometry and enables easy integration with multiphysics.

• Assign materials
  Materials can be defined using SolidMedium, which requires specifying heat capacity and thermal conductivity, or FluidSpec, which represents a non-simulated fluid.

• Assign boundary conditions
  These can be:

  • TemperatureBC

  • ConvectionBC

  • HeatFluxBC

• Add a heat source
  Use the HeatSource object to define a volume heating source.

• Define meshing specifications
  The simplest option is to use the UniformUnstructuredGrid mesh type, where you only need to specify the grid size dl. The mesher will automatically generate a mesh that fits the structures while respecting the given resolution. For more information about meshing options, please refer to our technical article heat-solver-introduction.

• Create the simulation object
  Create a HeatChargeSimulation object.

• Run the simulation
  Use Web.run, just like with an FDTD simulation.
