Physics Toolbar

Once physics interfaces are added to the model, the ribbon toolbar (Windows) and the contextual toolbar (macOS and Linux) are replaced with a custom physics or mathematics interfaces toolbars for the selected interface, which contains many of the common features and actions required to add physics and mathematics features for that interface to the Model Builder.

Physics
—	Various – the physics interface name	Any physics interfaces added to the selected Component are listed. Click to go to the node in the Model Builder and open the Settings window. See Physics Interface Guide.	The Physics Interfaces
	Add Physics	Open the Add Physics window to add physics interfaces to the current component.	The Add Physics Window
	Add Multiphysics	Open the Add Multiphysics window to add applicable multiphysics couplings to the current component.	The Add Multiphysics Window
	Add Mathematics	Open the Add Physics window with the Mathematics branch selected and expanded to add mathematics interfaces to the current component.	The Add Physics Window
	Insert Physics	Open the Insert Physics dialog box to insert physics interfaces in the current model component from another model file.	Adding and Inserting Physics Interfaces
	Insert Physics From	Open the fullscreen Select Model window insert physics interfaces in the current model component from another model file in a database or by browsing.	Adding and Inserting Physics Interfaces
Geometric Entity
	Domains	See Table 3-3 for a list of all the icons by space dimension. Available physics features for the physics interface are listed. To add subnodes, however, you need to right-click the parent node.	About Geometric Entities About Selecting Geometric Entities

Contextual
—	Attributes	Subnodes that can be added to a main (parent) node. 0D, 1D, 2D, and 3D	For example, Damping (a subnode to Linear Elastic Material). When available, Harmonic Perturbation is added from this menu as an exclusive node. See Harmonic Perturbation — Exclusive and Contributing Nodes
	Load Group	After adding a Load Group to the Global Definitions branch you can activate it in one or more load cases.	Using Load Cases
	Constraint Group	After adding a Constraint Group to the Global Definitions branch you can activate it in one or more load cases.	Using Load Cases
	Harmonic Perturbation	Click this to add Harmonic Perturbation as a contributing node.	Harmonic Perturbation — Exclusive and Contributing Nodes
Deformed Mesh
	Moving Mesh	Add moving mesh nodes under Definitions.	Moving Mesh Features
	Deformed Geometry	Add deformed geometry nodes under Definitions.	Deformed Geometry Features
Optimization
	Optimization	Add optimization nodes.	See the documentation for the Optimization Module.
Multiphysics
	Multiphysics Couplings	This menu contains any physics features that provide multiphysics couplings likely to be used for the set of physics interfaces added to the Model Builder.	Multiphysics Modeling Workflow and The Multiphysics Branch
	Shared Properties	From this menu you can add Model Input and, if your license includes it, Ambient Properties nodes under Shared Properties.	Model Input
Reduced
	Reduced-Order Modeling	To show this section, select the Reduced-Order Modeling check box in the Show More Options window. The menu contains reduced-model commands and the possibility to add Random Vibration nodes.	Reduced-Order Modeling
Thermodynamics
	Thermodynamics	This section is available with a license for the Battery Design Module, Chemical Reaction Engineering Module, Fuel Cell & Electrolyzer Module, or Liquid & Gas Properties Module. It contains a menu with commands for defining species and creating and importing thermodynamic systems.	See the documentation in the Battery Design Module, Chemical Reaction Engineering Module, Fuel Cell & Electrolyzer Module, or Liquid & Gas Properties Module.
