Physics

Contains all of the properties associated with the physics in the model.

Each physics type (mechanical, thermal, etc.) has a separate object.

Multiple physics definitions in a single simulation create a coupled multiphysics simulation.

Fields

physics_type: PhysicsType, default = NONE
physics: PhysicsType, default = NONE

The physics type.
solver_name: String, default = ""

A reference to a named set of solver options.
boundary_conditions: Vector of BoundaryCondition, default = []

Boundary and loading condition definitions.
initial_conditions: Vector of InitialCondition, default = []

Initial condition definitions.
field_set_type: FieldSetType, default = NONE
field_set: FieldSetType, default = NONE

Options for initializing and setting fields throughout a simulation.

Fields can be initialized from checkpoint files (.hdf5) generated in previous simulations or from Constant/Function/Expression values.
active: Bool, default = true

Flag to indicate whether this physics is actively solved during the simulation.
- true: Physics is actively solved.
- false: The primary fields are set but not actively solved.
rigid_bodies: Vector of RigidBody, default = []

RigidBody definition
connectors: Vector of Connector, default = []

Connector definition
deformable_bodies: Vector of DeformableBody, default = []

DeformableBody definition
