Assign properties to the material¶
- class Material(name, description='', materialIdentifier='')[source]¶
Bases:
MaterialBaseA Material object is the object used to specify a material. The Material object stores the various settings that determine how a material behaves. A material is created by combining one or more individual material options and sub options. A particular material option is associated with the Material object through a member. For example: the acousticMedium member may contain an AcousticMedium object. The alternative of having a MaterialOption abstract base class and a container of MaterialOptions was rejected because it would make it more difficult to enforce the fact that one Material object cannot contain two AcousticMedium objects, for example.

objectA Material object is the object used to specify a material. The Material object stores the various settings that determine how a material behaves. A material is created by combining one or more individual material options and sub options. A particular material option is associated with the Material object through a member. For example: the acousticMedium member may contain an AcousticMedium object. The alternative of having a MaterialOption abstract base class and a container of MaterialOptions was rejected because it would make it more difficult to enforce the fact that one Material object cannot contain two AcousticMedium objects, for example.
