Module: Boundary Conditions (Tetra) ()

Description:

The Boundary Conditions module visualizes boundary conditions defined in a tetrahedral grid for a finite elements simulation.

Visible faces are stored in an internal buffer similar to the Tetra Grid View module. Likewise, the selection domain can be restricted interactively by adjusting a selection box. Ctrl-clicking on a face makes it invisible.

Ports:

Boundary Conditions

This port provides a menu where all boundary condition ids occurring in the input grid are listed. Faces belonging to the selected id are displayed using a red (highlighted) wireframe in the viewer. You may crop the faces by turning the viewer into interactive mode and move the green handles of the selection box. Only the faces inside the bounding box can be added to the buffer.

Buffer

The Buffer buttons give you some control of the internal face buffer of the Boundary Conditions module. Only the faces present in the buffer are displayed according to the current drawing style. The Add button adds the highlighted faces to the buffer. The Remove button removes highlighted faces from the buffer. The Clear button removes all faces from the buffer. The Hide button deselects all faces but does not change the buffer.

Draw Style

This option menu lets you select between different drawing styles:

• Outlined: The faces are shown together with their edges.
• Shaded: The faces are shown.
• Lines: The edges of the faces are rendered as a wireframe.
• Flat: The edges of the faces are rendered as a wireframe without lighting.
• Points: Only the vertices of the faces are rendered as points.
