New and Improved General Functionality in COMSOL Multiphysics

•

A new Add Multiphysics window provides a list of available predefined multiphysics couplings for the selected physics interfaces (previously available only in the Model Wizard). Adding such a multiphysics coupling to a model components adds the corresponding multiphysics coupling nodes under the Multiphysics node. The Add Multiphysics window makes it easier to create multiphysics models incrementally.

•

In parameters, variables, and most applicable settings in the physics interfaces, you can type Ctrl+Space to choose from a list of available and applicable parameters and variables (or start typing text for a list of possible variables). This functionality was previously only available for postprocessing. You can also click the Insert Expression button underneath tables of parameters and variables.

•	You can now edit expressions in the Equation View nodes’ Settings window for the main physics interface nodes and for coordinate system nodes.

•	When saving COMSOL Multiphysics application files, you can choose to optimize for speed or file size when saving files. The speed option uses uncompressed MPH files.

•	The Find tool for finding variables and expressions now also works for Equation View.

•	You can now click on the column headers in the Variables table in an Equation View node to sort the table alphabetically.

•	The Range dialog box now includes an option to create a logarithmic range, for example, for a frequency range.

•	It is now possible to copy and duplicate View nodes in the model tree.

•	The Duplicate action can now be performed using the keyboard shortcut Ctrl+Shift+D.

•

With applicable time-explicit physics interfaces in the Acoustics Module, RF Module, and Wave Optics Module, a new Absorbing Layer node is available under Definitions. It adds an absorbing layer (sponge layer) to a time-explicit simulation. The absorbing layers work by combining three techniques: a scaling system, filtering, and simple nonreflecting conditions.

•	It is now possible to override the automatic mapping of the orientation of the source and destination for periodic conditions. With this option, you can create more general periodic conditions.

•	You can now double-click to add a geometric entity from the Selection List to a list of selected entities in a Settings window.

•	Support for general numerical flux has been added to the Wave Form PDE interface.

•	For models in user libraries added in the Application Libraries window, the Open PDF Document button will be available if there is a PDF file with the same name as the MPH file in the same directory.
