STAAD.Pro Help

Mesh Parameters dialog

Used to specify the parameters used for automatically generating a finite element mesh over boundary area.

Opens when a new mesh boundary has been defined from the Parametric Models dialog.

Note: The meshing features described here requires STAAD.Pro 2007 (build 03) and higher.
SettingDescription
Meshing Method

Select one of the following mesh methods:

  • Basic - Can make use of any of the three Boundary Connectivity (meshing type) options but only supports Triangular elements.
  • Standard - Can use type B or C Boundary Connectivity (meshing type) and only supports Quadrilateral elements.
Element Type

Select either to use Triangular only or predominantly Quadrilateral elements.

  • Triangular - Only triangular elements will be created.
  • Quadrilateral - This will create principally four sided elements, but where the geometry dictates, some places may require triangular elements.
Boundary Connectivity
  1. Only use selected boundary nodes, boundary edges not divided - Meshing will be done without creating any nodes along the edges of the boundary we defined. Thus, the entire distance between 2 sequential nodes will form the side of one triangular element. In most cases, this can lead to poor quality elements, and is best avoided.
  2. Divide boundary segments with specified divisions -
  3. Divide boundary segments to optimize mesh quality - (Default, recommended) Automatic boundary divisions.

The figures in the dialog correspond to the appropriate options.

Target element size Specify a target dimension to use as a guideline when automatically generating the mesh. This value is nominally used when dividing the boundary region into finite elements, but the element size is also determined by other factors such as the distance between boundary and other density points..
Default Number of Divisions of Boundary Edges Specify the number of boundary edges to use along a boundary segment.
OK Closes the dialog and generates the mesh. If you are using the Geometry | Parametric Model page, a dialog opens asking if you wish to add openings to the mesh.
Cancel Closes the dialog without generating a meshed surface.
