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. Overall though, a nice tutorial for beginners.This article provides recommendations related to hardware for SOLIDWORKS Simulation and SOLIDWORKS Flow Simulation software. It's better to bury the RRF body into the way and define any walls that it crosses as Stators (in the Wall boundary condition). If you are performing an internal calculation with a RRF, then best practice is to still extend the RRF body beyond the rotating impeller, even if it goes into the solid housing around it. I also typically recommend to define a volumetric mesh control using the RRF cylinder for these solutions. Thus having a few (say 2-3) computational cells between the rotating impeller body and the diameter of the rotating RF cylinder is of utmost importance. The idea here is that you are solving the RRF separately from the global (rectangular) computational domain and the solver needs to transfer information back and forth. Thust would come from Force surface goal.īecause you are solving this problem using a rotating reference frame (RRF) approach, then in Step 2, you should make the cylindrical sketch (representing the RRF) slightly larger than the rotating propeller. Once again, Best thrust with less torque is the best choice. Take the best result from above and define a new parametric study.įix speed of advance (-Vz) and check a range of RPM around the required one. The goal is to overcome the hull drag, with the minimum required torque. Then, with fixed RPM, a range of fluid speeds around the required Ship speed, must be studied(-Vz in this model). Īs first step, an initial guess of the ship service speed, propeller RPM and hull drag must be known. In quite a rough way the thing would go as follows. It means that flow motion, thrust and torque are going to be computed for the "static" propeller condition which for most cases is not practical.įor a real analisys, a parametric study would be the way to go.
