When adding a Material Property node as an input under a feature or property, you can choose a basic property type or, among other options, a property type defined locally in the current Physics Builder file. The latter choice refers to a Material Property Group node.
A Material Property Group (
) contains a set of material properties, which can be selected from a list of basic material properties or be customized. When defining a material property group, physics interfaces can use its properties through a material property, and you can also add values to a material library database.

Each material property group can be categorized under one or several group categories. This simplifies access in the Material node in the Model Builder. To create a new parent for the current property group, click the Create New Parent button (

In the Name field define a string that identifies the property group. It must be unique among all property groups available to materials. COMSOL Multiphysics displays the text entered in the Description field for the property group in the Material properties section of the Material node in the Model Builder.
