CST2013: Background Properties

Home: Materials Background

This dialog box helps you to fill the undefined space within the boundaries. You may define its material properties. Additionally, you may add some space between the bounding box of your model and the boundaries that will be filled with the background material.

Material properties frame

Material  type: Set the material type of the background material. The available material types are PEC, Normal, Anisotropic and Lossy Metal. (See Material Parameters: General for details)

Properties: Use this button to modify various background Material Parameters.

Multiple layers: With this checkbox you may activate or deactivate the multiple layers feature. If activated, the dialog expands and new input options appear.

Surrounding space frame:

Apply in all directions: If this checkbox is activated, the value in lower X distance is applied in all directions. The remaining input fields are grayed out. Therefore, you do not need to enter the same value six times if it is the same for all directions.

Lower X / Upper X / Lower Y / Upper Y / Lower Z / Upper Z distance: This dialog group can be used to add some extra space around your structure. An open boundary, in particular, requires this extra space to operate properly. All numbers must be positive.

Multiple layers:

Using the stackup editor, you may define multiple layers (layer stackup) by entering the height of the layer and the consisting material. Select the material to which this shape will be assigned from the list of previously defined materials or create a new material by selecting [New Material...]. You may also load a material from the material library by selecting [Load from Material Library...]. Also, some WCS will be created after defining one or more layers that are aligned at the bottoms of the layers.

Orientation: Sets the normal axis of the background items.

Delete: To delete a layer from the above named table after selecting it.

Insert: To insert a layer before a selected position.

X/Y/Z offset: Defines the value all layers are aligned on. Usually on the bottom line of the lowest layer. But also layers with negative thickness can be defined below the align value.

Invert direction: Normally all layers are aligned along the axis defined by 'Orientation.' This checkbox can be used to invert the direction.

Fix transversal: To fix the actual measurement of the layers. So the layers will no longer depend on the bounding box.

OK

Accepts your settings and leaves the dialog box.

Apply

Accepts the input without closing the dialog.

Close

Closes this dialog box without performing any further action.
