atl_eqn_heat_module Module

  1. atl_eqn_heat_module.f90
  2. atl_eqn_heat_module

A module describing the heat equation.

The heat equation is the simple scalar equation that utilizes the Laplacian operator in space:

Where represents the temperature. The only parameter that needs to be configured for this equation is the diffusivity parameter . Thus the equation table for the heat equation takes the following form:

  equation = {
    name = 'heat',
    k = 1
  }

The heat equation is implemented for 1, 2 and 3 dimensions, which are configured by choosing the corresponding name:

  • heat (3D)
  • heat_2d (2D)
  • heat_1d (1D)
