Best Computer For Ansys

Ansys is a program used for engineering simulation, and is applicable to virtually any field of engineering. As such, a specialised PC for Ansys would be a useful tool for any engineer.

In this article, we’ll be talking about the components you need to build the best workstation PC for Ansys.

CPU – Single-Thread or Multi-Thread?

Different software makes use of the CPU in different ways. To elaborate, certain software has tasks that use multiple cores, but other programs only really use 1 or 2 cores. 

Frequency is often conflated with this kind of performance, but this is not always the case. IPC (Instructions per Clock) is another important factor, and benchmark comparisons are more important than comparing GHz.

This makes it important to have the latest generation processor and platform in your system. Each new generation of processor will have increased single-threaded performance over the previous.

The benchmarks above show how CPU performance can very between generations and platforms. 

A Threadripper is better for multi-threaded tasks, but is outperformed by a much more affordable Ryzen 7 in single-threaded processes. 

A previous generation i9 costs more than the Ryzen 7 and even has a higher boost frequency (5.0GHz vs 4.7GHz) but is outperformed in both areas.

CPU – Frequency

Ansys benefits from both CPU frequency and core count.

It is recommended that you opt for the fastest CPU with a high core count available within your budget.

In a PC for Ansys, we would recommend an AMD Ryzen CPU. These CPUs boost up to high frequencies, and also feature great IPC. 

CPU – Core Count

As mentioned above, Ansys needs a lot of cores as well as high CPU frequencies. 

Ryzen CPUs are excellent for their high speeds, but it’s possible that you’ll need even more cores than a Ryzen 9 can offer. 

This is especially true when we consider that hyper threading does not add to performance in Ansys – this software benefits from physical cores. 

For these reasons, you may want to consider a Xeon or Threadripper if your budget allows for one (or even two). You should still aim for the fastest Xeon CPU/s available.

GPU

A strong GPU is not necessary in a workstation PC for Ansys. We should also point out that it is not necessary to use a Nvidia Quadro graphics card for this application. We have found greater performance from regular Nvidia GeForce graphics cards, and these cards also have the benefit of being more affordable than Quadro cards with similar specifications.

As such, a GTX1650 will have you covered, and also makes working with multiple monitors a lot easier.

RAM

16GB is the minimum requirement for this software. This is a good starting point, but for software like this, we would suggest throwing in all the RAM you can afford.

64GB seems to be a great sweetspot, although depending on the size of your projects, you might even want to consider 128GB. This will also make your computer a lot more futureproof, and make multitasking a lot easier.

Storage

Storage technology has come a long way over the past decade. Solid State Drives are known to be much faster than mechanical hard drives, but they’re also seen as pretty expensive.

It was pretty common to install the OS on a 120GB SSD, and everything else on a 1TB HDD, so that you could at least start up your PC super quickly.

Recently it’s become more viable to just use a larger SSD, from around 500GB to 1TB, and this is exactly our approach with our PCs. Having everything stored on SSDs means you’ll be able to save and load programs, and also transfer data, at incredible speeds. The SSDs we use are M.2 form factor and use the NVMe protocol, which means they take up no additional space in your case, and are even faster than standard 2.5” SATA drives.

Our Apollo systems currently feature PCIe 3.0 SSDs, and our Vulcan and Hydra system include even faster PCIe 4.0 SSDs.  

SATA vs PCIe

You also still have the option of adding in some HDDs if you need to store projects and media you are not actively working on. We would recommend adding these in at a later stage so you can prioritize parts like the CPU. 

Why choose us?

Often when you purchase a prebuilt system, it hasn’t even been switched on. If you’ve taken a look at our “Why Us?” page, you’ll already be aware of our unmatched assembly and testing processes, our swift and effective customer support, and our extensive technical knowledge and expertise.

Our team is comprised of lifelong computing enthusiasts with backgrounds in computer hardware and software, and we’re able to spot and resolve errors before the system is even shipped. By the time you receive your system, the likelihood of any kind of failure is as close to zero as possible. If you do encounter any issues, we’ll most likely be able to sort it out for you remotely, and in that rare case you’ll need to send the system in, you’ll be covered by our 3-Year (or 4-Year) warranty and lifetime hardware support.

Our systems combine the performance of enthusiast grade components and the stability of professional workstations. Yes, there are other places you can spend your money, but in terms of actual performance and quality, we simply have no competition. 

Conclusion

As we said before, each Modena Computers Workstation is custom built to the workflow and budget requirements of its user. It’s important to consider other programs you may want to use with this workstation.

During our consultation process, you can let us know exactly which programs you want to use with your machine, and we’ll be happy to help you understand what you need. 

Keep in mind that opting for higher performance right out of the gate offers much greater value than getting exactly what you need right now. A higher performance PC won’t need downtime to upgrade any time soon, and will also allow you to complete more work in less time. It could pay itself off a lot sooner than a more affordable option.
