ADHeatConduction

Description

ADHeatConduction is the implementation of the heat diffusion equation in HeatConduction within the framework of automatic differentiation. The ADHeatConduction kernel implements the heat equation given by Fourier's Law where The heat flux is given as (1) where denotes the thermal conductivity of the material. can either be an ADMaterial or traditional Material.

This class inherits from the ADDiffusion class.

Same as Diffusion in terms of physics/residual, but the Jacobian is computed using forward automatic differentiation

  • use_displaced_meshTrueWhether or not this object should use the displaced mesh for computation. Note that in the case this is true but no displacements are provided in the Mesh block the undisplaced mesh will still be used.

    Default:True

    C++ Type:bool

    Options:

    Description:Whether or not this object should use the displaced mesh for computation. Note that in the case this is true but no displacements are provided in the Mesh block the undisplaced mesh will still be used.
