Use the Automatic Surface Mesh command to access the tools that will enable you to automatically create unstructured domains on a watertight database model
based on specified meshing resolution goals and grid quality constraints.
In the solid modeling approach, Pointwise creates database models and quilts
while importing the initial CAD data (File, Import,
Database). Models are topological CAD entities that allow for watertight meshing over gaps and cracks existent in the underlying
geometry. Quilts, on the other hand, are meshing regions defined at the CAD level.
The recommended starting point to use the Automatic Surface Mesh command is a watertight database model with the meshing regions properly defined
(i.e. a quilted watertight model). Once these initial conditions are met, the command is designed to create an unstructured surface grid constrained to the
underlying database model in an automated manner. The objective of this command is to create the desired surface grid with minimum and intuitive input in the
form of meshing goals. Furthermore, these goals fall into two main categories: mesh resolution (i.e. target sizing) and mesh quality constraints.
Upon invoking this command, you will be presented with the Automatic Surface Mesh panel shown above. The panel is split into three
tabs: Global, Local, and Advanced.
- Global: This panel presents the geometric characteristics of the selected database models. It also contains tools to define the meshing
resolution goals and its quality constraints.
- Local: This panel contains tools for adjusting the display style within the Automatic Surface Mesh command and for assigning
specific target edge lengths on a per-quilt basis.
- Advanced: This panel presents additional advanced parameters to control the characteristics of the surface mesh to be created. It also
contains tools to enable/disable 2D T-Rex for specific boundary types.
Note: All the settings in the Automatic Surface Mesh functionality are stored in the Pointwise project file as part of the
Pointwise environment. Additionally, this settings can also be stored in a separate environment file using
the Save Environment As command available in the File menu. This capability enables you
to reuse the same Automatic Surface Mesh settings with different geometries without the need to re-define them.
