Reducing CFD simulations by more than 27% with ANSYS ® ICEM CFD™ Overview Overview Testimonial Testimonial Challenge Challenge We run large time-dependent problems. The radiation CFD models are particularly time consuming and may require several months of computation time. The challenge is to reduce this solving time by reducing the number of cells in these complicated models, but without loosing accuracy. Solution Solution ANSYS ICEM CFD offers excellent features, such as natural size, mesh density control, and tetra-to-hexa conversion. These automatic features make it easy to significantly reduce the number of cells in a model without losing accuracy. This enables us to get the solution within a reasonable computation time. ANSYS ICEM CFD is a user-friendly meshing tool. It includes everything you need to generate a complete and good quality mesh for various CFD solvers. Benefits Benefits We like the following features of ICEM CFD: • Integrated and user friendly interface • Tolerant of very bad CAD geometry • Ability to work with a combination of CAD and faceted geometry • Very good hexa meshing • Easy to control the mesh size • Able to run with multiple processors • Good technical support “At Dürr, we have been using ANSYS ICEM CFD for seven years. It is our major meshing tool. ANSYS ICEM CFD allows us to quickly generate various types of mesh with a high quality over a complicated three-dimensional geometry. Also, using ANSYS ICEM CFD has reduced the time required for our CFD simulations by more than 27%, which is significant.” Guang Yu CFD Engineer, Ph.D. Dürr is one of the world’s leading suppliers of production systems for the automotive industry.
