In terms of the effect of memory on performance, you either have enough or you don’t. EMAG products more often require more memory and 100+GB is recommended. As of 2016, 64GB of memory has been sufficient for 90% of the FEA and CFD projects completed by OEI engineers. The actual memory required for a particular problem will depend on the mesh, physical models that are enabled, and domain complexity. It is best to have as much memory as financially feasible. Please consult Ansys if you are considering Quad-Core.Ī minimum of 16GB of memory is recommended. NOTE: Quad Core Sockets – In many cases Ansys does not recommend quad core socket systems because of memory bandwidth. Our engineers tend to work with multiple monitors to efficiently move between applications. Accessories – A 3D mouse helps navigate complex models.Interconnects – High-speed interconnects (Mellanox Infiniband) enable clustering.Other Ansys applications can take advantage of GPU hardware to speed up solutions. GPU – Ansys Discovery Live requires an appropriate GPU to run.Graphics – A discrete workstation graphics card is recommended to interact seamlessly with complex models.Storage – Determines how much data can be held on the system, and how quickly it can be input/read.A good metric to compare between CPU options is (Clock Speed * Number of Cores / Cost). CPU – Number of cores and clock speed determines how quickly a model can be solved.RAM – Determines maximum model size (DOF, Degrees of Freedom) that can be solved.When engineers at Ozen Engineering are considering a new system, the components that we are most concerned about, by priority, include: This page is a resource for engineers looking to make informed hardware decisions. There are several factors to balance when considering a new system. Choosing the right hardware to use with Ansys tools will have a significant impact on productivity in terms of model size, performance, and user experience.
