Centrifugal pump fluid analysis machine

We received a request from a customer involved in the development of pumps who wished to introduce a dedicated water flow analysis machine for the development of centrifugal pumps.

Specific requests are as follows.

・ The number of parallels for the scFLOW solver under contract is "4", and even if the number of parallels for pre and post is added, the maximum number of parallels is "6".

・Since the CPU temperature tends to be high when the solver is running, I want to be able to suppress heat generation.

・I want to reduce the load on the video card and CPU in consideration of the life of the hardware.

・I want a CPU with a high clock speed.

・I want 64GB of memory

・ I want you to include a 27-inch display

・The budget is assumed to be around 50 to 60 yen.


We propose a configuration that fits your budget.

【Main Specifications】

CPU AMD Ryzen7 7700X (4.50GHz 8 cores)
memory 64GB
Storage 1 2TB SSD S-ATA
Video Nvidia T1000
network on board (2.5G x1 10/100/1000Base-T x1) Wi-Fi x1
Housing + power supply Middle tower case + 850W
OS Microsoft Windows 11 Pro 64 bit
Other CPU large water cooling unit
27-inch wide LCD display

When selecting a CPU, it is necessary to pay attention to the following points.

■ Points
・A CPU with a high clock speed generates a large amount of heat.

· "I want to suppress the CPU temperature during solver execution"When"I want a CPU with a high clock speed' are contradictory.

Therefore, our proposal is to increase the cooling capacity by installing a large water-cooled cooler.
Regarding the CPU, as far as the scFLOW official website is concerned,Parallel processing is performed with high efficiency up to around 16 cores, so, within your budgetA product with a relatively large number of cores and a high number of clocksis selected.

As for the video card, the product that the customer is currently using is the Quadro FX1800. NVIDIA T2000 is selected considering the large performance difference due to the difference in

In addition, we received the following questions from our customers.


I have heard that Ryzen generates more heat than Intel CPUs.
I understand that a large water-cooled cooler is installed because it generates a lot of heat, but since it is water-cooled, can I assume that the noise of the fan rotation is at a level that does not bother me?

Currently, AMD products generate less heat than Intel products with high-clock specification CPUs.
Also, since the configuration in this case is not an overclocking specification that generates a lot of heat, there is no need to rotate the fan at high speed with respect to the radiator.Therefore, it is assumed that it will operate at a general level of fan noise.
However, if you increase the rotation speed of the fan to improve the heat exhaust efficiency of the radiator, you can keep the temperature on the CPU side low, so the key point is how to set the balance between fan sound and temperature.

The configuration of this case study is based on the conditions given by the customer.
Please feel free to contact us even if you are considering different conditions from what is posted.



・What is scFLOW?
scFLOW is a new-generation CFD software developed with the aim of being a practical and robust tool while incorporating the latest technology.It has a preprocessor that allows even beginners to build complex models and create high-quality meshes.

・What is SC/Tetra?
SC/Tetra is the name of an unstructured grid general-purpose three-dimensional thermo-fluid analysis system.General-purpose thermo-fluid simulation software that employs a hybrid mesh to accurately capture the surface shape.

・What is a water-cooled CPU cooler?
There are two main types of CPU coolers: air cooling and water cooling.
■Air-cooling cooler: A mechanism to dissipate heat by transferring the heat of the CPU to an aluminum or copper heat sink and applying the wind of the FAN.
■Water-cooling cooler: A mechanism that transfers the heat of the CPU to the coolant liquid and dissipates it with the wind of the radiator and fan.
There are two types of water-cooled coolers, "full-scale water-cooled" and "simple water-cooled". It is difficult to interfere withIn addition, water-cooled coolers have high cooling efficiency and have a certain degree of freedom in mounting inside the CPU, but maintenance is required to prevent coolant leakage and loss.
