A mesh data model for CAD and CAE applications
Mesh Framework (OMF) provides data structures for linear meshes in one, two and three dimensions, together with display, selection, checking and editing tools. It integrates mesh data with Open CASCADE visualization and OCAF documents.
The framework stores node-to-element back references. An application can use these relationships when finding the elements attached to a node, editing a mesh or updating a local region, instead of treating connectivity as a separate application-level lookup.
Display and select the data your users work with
Meshes can be displayed in wireframe, flat-shaded, smooth-shaded and shrink modes. Selection can address individual nodes, elements, groups or sub-meshes. Applications can add their own display and selection modes for domain-specific interaction.
OCAF integration allows mesh data to participate in the application’s document model. This is useful in pre- and post-processing tools where the mesh, selected regions and associated application operations must stay connected.
Check and edit mesh geometry
| Operation | Practical use |
|---|---|
| Free-boundary detection | Locate open boundaries before downstream processing |
| Area and enclosed-volume calculation | Obtain geometric measures where the mesh is suitable for the calculation |
| Mesh intersections with a line, plane or mesh | Build probing, sectioning and intersection workflows |
| Boolean operations on surface meshes | Combine or modify surface-mesh geometry |
The documented exchange interfaces include MSC/NASTRAN, OBJ and STL. Specify the required direction and element representation during integration; these formats do not carry identical mesh information.
Mesh framework or mesh generator?
Choose Mesh Framework when the application needs to store, inspect, select and edit mesh entities. Choose Express Mesh when the task is to generate a surface mesh from CAD geometry. BRepGraph Advance provides graph-native modeling, meshing and relation analytics for a different application data model.
The delivery includes a user guide, reference manual and programming sample. Discuss OMF evaluation with your element types, editing operations, document requirements and representative model sizes.
