Fluid simulation machine

A customer involved in systems engineering research contacted us with a request to consider purchasing a machine for fluid simulation within a budget of 60 yen.
Currently, we are conducting research using Ansys Fluent, and are concerned about the occasional freezing of our existing PC. The calculations we handle are on a scale that takes several days to complete, so we would like to introduce a new PC to solve the problem.

I have heard that the freeze occurs when Ansys is performing repeated calculations, but does not occur when Ansys is not being used. It is unclear when the freeze began to occur, and there is about 600GB of free space on the SSD.

The current PC configuration is as follows:

CPU: Core i9-10980XE
Memory: 256GB
OS: Windows 10 Pro

Taking these discussions into account, we proposed the following structure:

CPU Intel Core Ultra 9 285K 3.70GHz(8C/8T)+3.20GHz(16C/16T)
memory Total 192GB DDR5-5600 48GB x 4
storage 2TB SSD M.2 NVMe Gen4
Video NVIDIA RTX A1000 8GB (MiniDisplayPort x4)
network on board(2.5GBase-T x1) Wi-Fi x1
Housing + power supply Mid-tower chassis + 850W 80PLUS GOLD
OS Microsoft Windows 11 Professional 64bit

These specifications were considered to be the most computationally efficient configuration within a budget of 60 yen.

The memory capacity of this configuration is 192GB, the maximum capacity. Although it was decided after considering the balance between budget and specifications, the memory capacity of this configuration is less than that of the machine you are using. The scale of calculations that can be processed by the PC depends on the memory capacity, so please check the memory required for the calculation.
*If you have any questions, please feel free to contact us.

In addition, the RTX A1000 8GB is used as the GPU for screen drawing.

About Ansys freezing

Since we are unable to see the PC you are currently using, it is difficult to pinpoint the cause of the freeze, but based on the information we have received, the following possibilities are possible:

- Insufficient memory capacity
・Decreased processing capacity due to breakdowns or aging

In PCs that have been installed for several years, the power supply unit may be unstable, causing fluctuations in the power supply to the CPU under high load, resulting in freezing. It is also possible that dust has accumulated in the CPU cooler, reducing cooling performance, causing the computer to overheat and freeze when subjected to high load for a long period of time.

If the problem is caused by insufficient memory capacity, the memory capacity of this configuration may not be sufficient to resolve the issue. In isolating the cause of the problem, it is important to check the amount of memory required for actual calculations, so we recommend that you check this as a priority.
*If you would like us to diagnose the symptoms, we can take your PC and inspect it for you. Please feel free to contact us.
