Workstations for Autodesk CFD – new and refurbished

FAQ

What kind of computer setup should I choose for flow simulations in Autodesk CFD?

Autodesk CFD is fluid flow simulation software that places a heavy load on the processor and RAM. Workstations with a powerful multi-core CPU, plenty of RAM and a fast SSD work well. The exact configuration depends on the size of your models and the computational mesh, so it's best to tailor it to your own projects.

How much RAM do I need for simulations in Autodesk CFD?

RAM requirements grow with model complexity and the number of mesh elements. Smaller projects need less memory, while large, complex simulations will benefit from considerably more. Choose a workstation where the memory can be upgraded later, and check the software vendor's requirements.

Where should I focus my budget in Autodesk CFD: a powerful CPU or a top-end GPU?

The solver calculations are performed mainly by the processor, so the CPU and RAM have the greatest impact on simulation time. The graphics card is responsible primarily for smooth work with the model and for visualizing results. It should comply with Autodesk's recommendations, for example a professional workstation-class graphics card.

Is a refurbished (ex-lease) workstation suitable for Autodesk CFD?

Yes, as long as the hardware specifications meet the requirements of your simulations. Ex-lease workstations have a solid, professional build and can lower the purchase cost. Before ordering, check the processor model, the amount of RAM, the drive type and the warranty terms.

What is the difference between a new and a refurbished workstation for CFD work?

New hardware comes with the latest components and a full manufacturer's warranty. A refurbished model usually costs less and, in typical engineering tasks, often delivers similar performance. The choice depends on your budget, the scale of your projects and how important the latest-generation processors are to you.
