Unstructured Export Grid Model
+ Collaboration diagram for Unstructured Export Grid Model:

An unstructured grid model contains one or more block (PWGM_HBLOCK), domain (PWGM_HDOMAIN), and vertex (PWGM_HVERTEX) instances.

For a 3D grid:

For a 2D grid:

Since Pointwise does not restrict 2D grids to any particular plane or orientation, a vertex always defines an XYZ location (PWGM_VERTDATA) for both 2D and 3D grids. A non-planar, 2D surface grid can be built and exported from Pointwise. Enforcing solver specific restrictions is left to the exporter.

An element is defined by a list of model vertices (PWGM_ELEMDATA).
