To display the functionality described in this section, click the Show More Options button () on the Model Builder toolbar. Then, in the Show More Options dialog box, select the applicable option:

In the Show More Options dialog box, click the options that you want to include. At the bottom of the dialog box, click the Select All button () to select all options, or click the Reset to Default button () to restore the default settings (where only the Equation Sections option is selected). Click OK to accept the selected options and close the dialog box.

You can also open the Show More Options dialog box from the context menu for the Global Definitions, Definitions, Materials, physics interface, Study, and Results nodes.

By default all Equation sections, which show mathematical equations describing a physics node, appear on all physics nodes’ Settings windows. Clear this check box if you do not want to include the Equation sections.

Select this option to display the Equation View node under all physics nodes in the Model Builder.

Select this option to display the Consistent Stabilization and Inconsistent Stabilization sections on the Settings windows. If you have access to the Level Set and Mixture Model interfaces, it displays a Stabilization section instead.

Select this option to get access to options for adding extra dimensions under Global Definitions in the model tree. Extra dimensions can be used to extend a standard geometry with additional spatial dimensions.

Select Advanced Physics Options for a variety of settings for advanced physics options to take effect.

The Advanced section appears on some physics feature nodes’ Settings windows. This section does not normally appear unless the physics interface contains some advanced options.

This section controls how constraints are enforced, usually in boundary conditions. See Constraint Settings for more information.

There are additional settings, specific to some physics interfaces, that are also activated by the Advanced Physics Options check box. Also, the ISO preferred frequencies option, which appears in the Range dialog box, is controlled by this option.

Uses a batch process to solve a study on your computer as a batch job. If your license includes cluster computing, the cluster computing submits the batch jobs to a job scheduler which can run the jobs on a second computer or a cluster. If you select this option, you can right-click the Study node to enable Cluster Computing, Cluster Sweep, Batch Sweep, and Batch.

Sensitivity analysis can add sensitivity functions at the study level and use model parameters as global control variables. Select this option to add a Sensitivity study step.

Select this option to make it possible to add and define multigrid levels for multigrid solvers or preconditioners. Right-click applicable study step nodes to enable the Multigrid Level option from the context menu.

Reduced models are online reduced-order representations of a full COMSOL Multiphysics model. Select this option to enable access to reduced-order modeling tools on the Reduced-Order Modeling menu under Global Definitions and the Model Reduction study step under a Study.

Select this option to enable these options under the Study nodes: Job Configurations and Solver Configurations. These nodes also appear if they contain content. Right-click the Solver Configurations node to be able to select the option Create Custom Solver and add a Solver node without any added solver settings or other nodes.

Select this option to display the Views node under Results and make it possible to define additional views used during postprocessing.

Select the Override and Contribution check box to include the section in all physics nodes (for material models, sources, boundary conditions, and so on) and also in, for example, materials nodes under Materials and moving mesh nodes under Definitions. For a specific node, the Override and Contribution section in its Settings window contains lists of other nodes that the node is overridden by, other nodes that the node overrides, and other nodes that contributes with the node (to the total load or flux, for example).

Select this option to make it possible to add utilities for matrix variables, state variables, mass properties, and more from the Variable Utilities menus that you access by right-clicking a Global Definitions or Definitions node..
