This option allows the user to assign a material to one or more surfaces. When this option is selected, the following panel appears:
Assign Material panel
There are several options when assigning materials:
- Perfect reflective surface: Represents a material that perfectly reflects any wave that gets into it (that is, without attenuation).
- Perfect absorbing surface: Represents a material that perfectly transmits any wave that gets into it (that is, without attenuation).
- Material defined by reflection/transmission: This option allows the user to select a user-defined material to be assigned to a surface or object.
To assign a material, the user needs to select (in the geometry panel) the objects and surfaces they want to assign the material to, and then press the "Assign" button.
