VisTools/Mesh
The VisTools/Mesh library from Visual Kinematics, Inc. is an
object-based software development toolkit designed to provide
comprehensive mesh generation capabilities.
Features
- Fully automatic generation of triangular and quadrilateral surface
meshes and tetrahedral volume meshes.
- Mapped mesh, boundary layer and extrusion mesh generation.
Triangular, quadrilateral, tetrahedral, wedge, pyramidal and hexahedral
elements may be generated.
- Both linear and parabolic elements may be generated in all cases.
Unique capabilities exist to input parabolic triangular elements as input to
the automatic tetrahedral volume mesh module. Special attention is paid
to the parabolic surface triangulation during the meshing process
to provide unequalled robustness and quality
of the resulting parabolic tetrahedral mesh.
- Surface geometry is input to all meshing modules where necessary
as a triangular tesselation of the geometric surfaces. The user may attach
any number of associations to geometry to the tesselation, providing
user customized geometric associativity. This method of geometry
representation enables the following,
- CAD system and kernel licensing independence
- Regrid existing legacy finite element mesh.
- Mesh STL style geometry and output from CAD visualization systems.
- Arbitrary points and lines may be incorpated into a surface mesh.
Points, lines and triangles may be embedded into a volume mesh.
- Mesh sizing control may be done with any combination of
global element size, minimum element
size, curvature based sizing and growth rate parameters.
Specific sizing control may be placed on any number of arbitrary locations
in space. Sizing control may also be controlled by a user defined
function of spatial coordinates.
- Unique defeaturing and healing capabilities. Small holes, etc. may
be ignored and meshed over. Self intersecting surfaces may be repaired
and properly meshed in many cases.
