Pre-Processor : Meshing
ANSYS CFX-Mesh
ANSYS CFX-Mesh is an easy-to-learn, easy-to-use CFD meshing tool which produces high quality hybrid meshes for both simple and complex geometries.
As a highly-automated meshing tool within the ANSYS Workbench environment, ANSYS CFX-Mesh is closely coupled to ANSYS DesignModeler for geometry creation and meshing. Geometry can also be obtained directly from a variety of CAD packages.
Automatic 2-D, 3-D and extruded meshing: ANSYS CFX-Mesh can produce translational and axisymmetric 2-D meshes (meshes that are one element thick), allowing rapid prototyping for suitable geometries. A similar method can also be used to create extruded meshes. For 3-D meshing, ANSYS CFX-Mesh provides automatic surface and volume meshing. In regions of high surface curvature, the mesh is automatically refined in order to maintain the necessary geometric resolution. This control, which can be applied globally and overridden locally, greatly reduces the need for manual specification of mesh spacing.
3-D Proximity: 3-D proximity detection automatically refines the mesh in areas where geometric features are in close proximity and result in small spaces within the volume. This improves robustness and reduces user input.
Virtual Surface Capability: Many CAD geometries contain surfaces and edges that introduce geometrical features that the mesh unnecessarily resolves. ANSYS CFX-Mesh avoids this resolution by allowing surfaces and edges to be merged together with neighboring entities. This capability is extremely useful for geometries that contain “sliver” surfaces produced by CAD packages as a result of merging surfaces or bodies.
