Materials 6.2.10

2.4. Assign

The geometry properties assigned to materials can be edited by clicking on Materials Assign. After selecting this option, the surfaces/objects assigned to specific materials must be selected, and confirm the selection with the “Assign” button as shown in next Figure.

 

Assign Material panel

 

The following material assignment options can be applied to surfaces:

  • Number of Layers: to specify the number of layers to be considered in this object.
  • Selected Layer: to select the layer that is being edited.
  • Thickness: to assign a thickness to each layer.

For each layer, the user can select one of the following material types but can’t assign material properties defined by geometry, material properties defined by reflection coefficient, and material properties defined by electrical impedance to the same surface.

  • Perfect Conductor. The objects of this type of material are metallic or PEC (Perfect Electrical Conductor). This is the material selected by default.
  • Perfect Absorbing Surface. The objects of this type of material are perfectly absorbing.
  • Material defined by geometry. If there are materials defined with this type, it is possible to assign them by selecting from the combo box.
  • Material defined by reflection coefficient. If there are materials defined with this type, it is possible to assign them by selecting from the combo box.
  • Material defined by electrical impedance. If there are materials defined with this type, it is possible to assign them by selecting from the combo box. (Note: This feature is under development at this moment.)
  • Assign button. To confirm the changes.

In order to assign a material to a surface or an object, first, select this one on the screen and then choose the material to be assigned. Finally, click on Save button.
