Geometry AI Surface Mesher#
Geometry AI Surface mesher is a combination of a geometry processing utility with a surface mesher.
Main characteristics:
handles non watertight geometries,
handles intersecting solid bodies well,
allows for basic geometry transformations of solids (to use this feature, define solids in separate CAD files),
patches holes in the geometry,
allows for the analytical specification of a Wind Tunnel geometry as a farfield as well as creating a half-model for more efficient straight line simulations,
does not conform to feature edges, to improve their representation, the geometry accuracy must be increased.
Meshing Process#
The surface mesher performs two main steps:
Geometry Processing
Through the use of Geometry AI, the geometry is processed and prepared for surface meshing. This includes:
applying basic geometric transformations to solids,
resolving intersections,
patching holes in the geometry,
applying basic geometry transformations to solids defined in separate files,
constructing the farfield geometry,
splitting the geometry to create a half-model.
Surface Meshing
The geometry is meshed using the surface mesher which enables the user to specify all kinds of refinements, also per face of the input geometry.
Note
The Geometry AI mesher may stop before fully achieving the requested Geometry accuracy if system resource constraints are encountered during surface meshing. When this occurs, a message indicating early termination will appear in the process log. If you observe this, consider increasing the Geometry accuracy value (coarser) to reduce the meshing workload and lower resource usage.
Examples#
Examples of meshing using Geometry AI can be found in the Python API Example Library. Specifically look at:
Recommended for:
non-watertight geometries,
faulty low quality geometries,
intersecting solid bodies,
geometries of automotive production vehicles.
