For a practical analysis, a much finer mesh can than be crafted, while a coarser mesh (for rapid simulations) may be displayed so the connectivity can be readily observed. PC Build Comparisons Add a CPU to start your build. Up to 2 million total elements in a given mesh can be found within a boundary layer. A sliced view of a wing’s surface mesh and a 3D boundary layer mesh are then available for display for engineers. On various processors, colors signify mesh components. Trap wing in high lift configuration with initial and modified meshes may run concurrently, including in-plane boundary layer adaptation.įor a specific wing geometry, over 20 processors can be used to create a mesh, simultaneously.To execute large scale adaptive simulations without bottlenecks, there is a rich collection of data structures and API functions linked to partitioned mesh.Any MPI implementation is supported (MPICH, OpenMPI, MS-MPI, your own).On tens of thousands of processors, billions of elements worth of meshes have been created and modified.The majority of related serial capabilities include parallel support.Complete adherence to the actual CAD geometry.During mesh formation and adaption, there is automatic partitioning and load balancing.Happy Meshing, Everyone! Parallel Meshing Products by AnsysĬapabilities for Parallel Meshing in Ansys We hope you take advantage of this new advancement. If you would actually like to keep working, a specific number can be entered instead. By default, both of these are set to 0 which will permit Ansys to use all cores on the computer. One setting provides the number that can be used for the various mesh methods and the other will set the number that can be used for parallel part meshes. The picture below shows the location in the Options menu. The Number of CPUs that are available to Ansys can be specified in two places in Tool>Options>Meshing>Meshing. So, if the computer has 4 cores, a minimum of 8 GB of RAM will need to be on the computer.Īs an added bonus, other mesh methods (MultiZone Quad/Tri, Patch Independent Tetra, and MultiZone) will be able to use multiple cores as well. One requirement is that each core will need to have at least 2 GB of RAM available for its use. The image below shows a sampling of the speed increases that were witnessed by Ansys using several customer models.īy default, the program will attempt to use all cores on the machine. If the model is made up of a single multi-body part, the entire part will need to be sent to one CPU so the speed increases may not be fully realized. Since the mesh on individual bodies do affect each other, this allows Ansys to break the model into many pieces thus utilizing all cores. The speed-up is especially dramatic for models with lots of bodies connected together with contact regions. Ansys will attempt to divvy the geometry up between the cores so that more of the computer resources is used during this part of the analysis process. For those users that build large models, one new feature will be especially helpful in saving time.įor the first time, Ansys is able to use multiple CPUs to generate a mesh WITHOUT ANY ADDITIONAL LICENSES. In the latest release, several advancements were added to speed up the generation of parallel meshes in Ansys Workbench. Parallel Meshing and Remeshing | Efficient Model Optimization
