Ansys ICEM CFD

Today's sophisticated analysis environment requires geometry-integrated mesh generation and post- processing tools to streamline product development. If you're looking for a tool that maintains a close relationship with geometry during meshing generation and post-processing, then look no further than ANSYS ICEM CFD.

From CAD to mesh generation for analysis, ANSYS ICEM CFD provides sophisticated geometry acquisition, mesh generation, post-processing, and mesh optimization tools. ANSYS ICEM CFD is the only universal pre-processor for analysis including FEA, CFD and other CAE applications such as particle transport and computational electromagnetics. Used for engineering applications such as computational fluid dynamics and structural analysis, ANSYS ICEM CFD's mesh generation tools offer the capability to parametrically create grids from geometry in multi-block structured, unstructured hexahedral, tetrahedral, hybrid grids consisting of hexahedral, tetrahedral, pyramidal and prismatic cells; and Cartesian grid formats combined with boundary conditions.

With more than 100 flow solver and structural analysis translators provided to produce an input file containing mesh and boundary conditions, ANSYS ICEM CFD has revolutionized the link between CAD and mesh generation. For the first time, engineers and analysts have to learn only one software environment to pre-process (and soon post-process) for the many analysis codes often in use within a work environment.

Direct CAD Interfaces
A key component of the productivity savings from utilizing ICEM CFD is due to the industry unique Direct CAD Interfaces. Presently available for CATIA, CADDS5, ICEM Surf/DDN, I-DEAS, SolidWorks, Solid Edge, Pro/ENGINEER and Unigraphics, ICEM CFD's Direct CAD Interfaces enable the CAD model to be transferred directly into ICEM CFD, without requiring cleanup of third-party formats such as IGES or STL. Through the Direct CAD Interfaces, boundary conditions and grid size specifications can be applied in the CAD system, and carried all the way through to the solver. Parametric modeling is greatly simplified as this information is preserved with the original CAD model, even throughout design modifications.

Complete Meshing Suite
ANSYS ICEM CFD's highly automated mesh generation tools cater to virtually all topologies including all hexahedral, all tetrahedral, hybrid hex/tet element meshes, or Cartesian meshes. Additional elements that can be generated include prism and pyramid cells. Finally, surface/shell meshing with tri or quad elements are supported using either paving or Octree solvers.

Post-Processing
The ANSYS ICEM CFD PV3 is a flexible and customizable post-processor that interfaces with all the major CFD solvers.
