class Solid

Bases: PDEModelBase

Solid class for setting up the conjugate heat transfer volume model that contains all the common fields every heat transfer zone should have.

Example

Define Solid model for volumes with the name pattern "solid-*".

>>> fl.Solid(
...     entities=[volume_mesh["solid-*"]],
...     heat_equation_solver=fl.HeatEquationSolver(
...         equation_evaluation_frequency=2,
...         linear_solver=fl.LinearSolver(
...             absolute_tolerance=1e-10,
...             max_iterations=50
...         ),
...         relative_tolerance=0.001,
...     ),
...     initial_condition=fl.HeatEquationInitialCondition(temperature="1.0"),
...     material=fl.SolidMaterial(
...         name="aluminum",
...         thermal_conductivity=235 * fl.u.kg / fl.u.s**3 * fl.u.m / fl.u.K,
...         density=2710 * fl.u.kg / fl.u.m**3,
...         specific_heat_capacity=903 * fl.u.m**2 / fl.u.s**2 / fl.u.K,
...     ),
...     volumetric_heat_source=1.0 * fl.u.W / fl.u.m**3,
... )
