Solid

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,
... )

Attributes

material: SolidMaterial

The material property of solid.

initial_condition: HeatEquationInitialCondition, optional

The initial condition of the heat equation solver.

Default:

None

name: str, optional

Name of the Solid model.

Default:

None

entities: EntityList[GenericVolume, CustomVolume, SeedpointVolume]

The list of GenericVolume or CustomVolume or SeedpointVolume entities on which the heat transfer equation is solved. The assigned volumes must have only tetrahedral elements.

heat_equation_solver: HeatEquationSolver

Heat equation solver settings, see HeatEquationSolver documentation.

Default:

HeatEquationSolver()

volumetric_heat_source: str | Any

The volumetric heat source.

Default:

0 * fl.u.W/fl.u.m**3

Methods

classmethod ensure_custom_volume_has_tets_only(v)

Check if the CustomVolume object was meshed with tetrahedra-only elements.
