Volume Mesh Generation
Component surfaces are intersected before meshing to form a single wetted surface. This detects any geometry degeneracy in the configuration and corrects it automatically, thereby avoiding possible complications in the mesh generation process.
ANSYS ICEM CFD Cart3D software produces topologically unstructured, adaptively refined Cartesian meshes. The desired finest cell size can be achieved by controlling the initial mesh divisions and number of refinement levels. The adaptation region can be prespecified in the usual manner in ANSYS ICEM CFD using density control polygons.
Mesh generation operates on the order of 1M cells/minute on moderately powered workstations. Memory usage is approximately 14 words/cell, so that typically only 54MB is required to generate a mesh of 1M cells.
Currently the mesh can be saved in either an ANSYS ICEM CFD Cart3D native mesh format or in an ANSYS ICEM CFD domain file as un unstructured hex mesh. Translators can be provided within ICEM CFD to write the Cartesian mesh directly to any CFD solver format.
