Enabling Access to Model Settings in Your Simulation App
Using the Application Builder in COMSOL Multiphysics, you can choose which of the settings in your finite element model via the Model Builder that you want to make available for a user to access through your simulation app. Examples of this include allowing users to select a mesh density level (by enabling access to the predefinedElement sizeproperty) or to view a results plot for a time-dependent model at different times (by enabling access to the Time drop-down list for a plot). Here, we will demonstrate how to choose the model data for a user to access here.
Tutorial: Adding a Section and Using Data Access
Thesimplified thermal microactuator tutorial modelis used for the model example, which a simulation app was developed forpreviously. Here, the simulation app is extended by usingData Accessto selectively choose additional settings in the Model Builder to make available in the Application Builder. Namely, a new section is added that includes a combo box for users to select a mesh density level. Making changes and edits to the app is done using theForm EditorandEditor Toolswindow. Topics covered in the tutorial video include the following:
- Adding a section to an app
- Adding a local form
- Working with forms
- Form Collections
- Activating data access
- Developerribbon tab in the Model Builder
- Choosing settings to make available in the Application Builder
- Adding a combination box object
- Editor Toolswindow
