Absolute Mesh Size

If the Mesh size type is set to Absolute, the Absolute mesh size has to be specified.

Selecting the Info option by right-clicking on the corresponding surface group can be used to determine the dimensions of each of the geometric faces in the surface group. From that information, it is possible to determine an appropriate Absolute mesh size.

Selecting Info opens the Information Window dialog:
  • Parent Set: Gives the name of the parent geometric entity (the solid volume that the face is attached to).
  • Parent Volume: Gives the name of the group that the parent volume is assigned to.
  • Area: Area of the geometric face
  • Center: The approximate centerpoint of the facets that represent the face.
  • Normal: The averaged normal direction of the facets that represent the face.
  • X Min/Max: The min and maximum x coordinates of the facets that represent the face.
  • Y Min/Max: The min and maximum y coordinates of the facets that represent the face.
  • Z Min/Max: The min and maximum z coordinates of the facets that represent the face.
  • Dimension: The range of x, y, and z coordinates of the facets that represent the face.

Example

The following example will demonstrate the absolute mesh size specification on a simple box. This box has a height, width and depth of one meter.


Figure 1.

Only one surface was specified with meshing requirements. The other five surfaces were not prescribed mesh requirements so they will inherent the global mesh size.

Applying an absolute surface mesh size of 0.1 produces a mesh with elements at, or less than, 0.1 meter. The resulting mesh on surface "One" is shown below. Here there are 11 elements spanning across the edges of the surface "One" to ensure that the maximum absolute mesh size is less than 0.1 meters.
