Each core is divided into two “virtual” cores though each virtual core only has half the bandwidth and power. A system may show 4 cores with 8 logical processors, which indicates this is a quad core machine with hyperthreading enabled. It has been suggested that a single CPU with the same amount of cores has slightly better performance compared to the same amount of cores split over multiple CPUs. Power users typically favour between 4 and 12 cores, though recent tests have found that optimal performance scalability is 8 cores. Certain operations are inherently linear and therefore cannot take advantage of multiple cores. However don’t expect doubling the number of cores will cut your solution time in half. SOLIDWORKS Simulation and Flow Simulation do take advantage of multiple CPUs and cores. Given Simulation studies can be long to solve, the CPU will not be able to sustain peak speed.

It must remain within specification limits for workload, temperature and power. It may not reach these speeds in all scenarios or for an extended period of time. Look for a CPU speed closing in on 4GHz.īe aware that “Boost” or “Turbo” speeds represent the max speed that can be hit, but not sustained. Therefore the CPU Clock Speed would be the bottleneck as the other cores will not be used during this time. A number of Simulation processes can only utilize a single CPU core while solving. The CPU Clock Speed should be the first item to consider. SOLIDWORKS Simulation Hardware Computer Processor (CPU)Īll hardware of a computer is important to consider, but the CPU is still the most important component in terms of the speed for running Simulation studies. There is a general order of importance of hardware when running Simulation studies: View the SOLIDWORKS Workstations » SOLIDWORKS Simulation Hardware considerations NEW Dell Hardware offer for US Customers: Get a discount on a Dell Certified SOLIDWORKS Workstation through our partner TriMech. Purchasing a machine from a computer manufacturer ensures all components will work together correctly. Cooling and thermal management is also an important aspect. Custom machines can be a cheaper option, however selecting components individually may not be compatible or have bottlenecks. However the entire system should be designed and assembled for optimal performance. The following gives details on specific hardware components. This will provide much greater performance improvements compared to an overly expensive workstation. To learn more about tools and techniques to improve your Simulation studies, we recommend attending a SOLIDWORKS Simulation training course on the topic. You can learn more about general SOLIDWORKS hardware requirements for SOLIDWORKS 2021 on our blog.īe aware that more powerful and expensive computers may not solve simulation studies in a practical timeframe if best practices are not observed. This article provides recommendations related to hardware for SOLIDWORKS Simulation and SOLIDWORKS Flow Simulation software.
