2D Heat Structures

The following heat structures are 2D and share parameters that specify how to generate the 2D mesh:

Convergence

If using ComponentsConvergence, a Convergence object of type MultiPostprocessorConvergence is used that returns CONVERGED if all of the following are true and returns ITERATING otherwise:

where

  • is the temperature at iteration ,

  • is a reference temperature,

  • is a reference density,

  • is a reference specific heat capacity,

  • is the average element size on the heat structure,

  • is the tolerance for the temperature step,

  • is the tolerance for the residual norm, and

  • is the norm over the channel.

commentnote:One iteration required

This object always returns ITERATING for the first iteration due to the usage of step criteria.

The following parameters apply:

  • "T_rel_step_tol": The relative step tolerance for temperature ,

  • "res_tol": The residual tolerance ,

Note that to use this capability, solid properties must be specified using "solid_properties", since the reference temperature for each heat structure block is taken from "solid_properties_T_ref".
