Working with Methods > Creating Methods > Recording Code

Recording Code
This action makes it possible to insert code based on modifications of the embedded model. Put the insertion point where you want to insert the actions, click Record Code (), perform the actions in the Model Builder window, and then click Stop Recording (). The recorded code then appears directly in the method editor window. For example, if you update the size settings for a Rectangle geometry object as in the following figure,
the recorded code for that action appears in the method editor window:
When recording code, a red dot on a Method node indicates the method where the recorded code appears, and a red frame surrounds the method editor window for that method.
Recording a new Method
As a convenience, there is also an action on the Home ribbon toolbar for creating a new method and starting the recording. Click Record a New Method (), enter a name for the new method in the Record a New Method dialog box’s Name field, perform the actions that you want to record, and then click Stop Recording (). In this way, you in principle do not need to see any code to record a method. If a method editor window is open, the recorded code appears directly just as when using Record Code above. When you record a new method, a red frame surrounds the modeling and application builder windows in the COMSOL Desktop to indicate that code recording is active.
