Building structural analysis machine

・CPU: Xeon W-2265 3.50GHz 12 cores
・ Memory: 64GB
-Storage: 1TB SSD M.2
・Video card: NVIDIA RTX A2000
・OS: Windows 10

■ Points
-“We place more importance on efficiency of work time than analysis time, and we would like to introduce a machine that can operate comfortably even on models with many elements and points of contact.”In response to your request, change the GPU to A4000.

・The CPU is on the manufacturer's websitePriority should be given to single-core performanceBecause there is a description, select a product with high processing capacity per core.

・Since the recommended CPU Xeon W has the same architecture as the 11th generation Core series, considering the GPU installation cost and processing power per core,Select 12th generation Core i9.

■FAQ

・What is DIANA?
DIANA is a general-purpose structural analysis system based on the finite element method provided by DIANA FEA.It is used in the design of dams, embankments, and tunnels, and the analysis of underground structures, historic buildings, and large reinforced concrete structures.

・What is Patran?
Preprocessor/postprocessor software for finite element analysis (FEA) provided by MSC Software.
MSC Nastran, Marc, LS-DYNA, ANSYS, Pam-Crash and many other solvers are supported.

・What is single core performance?
Conventional CPUs had only one core, and increasing the number of clocks meant increasing the amount of calculations, which meant improving CPU performance.
However, this method increases heat generation and power consumption and poses a problem in terms of stable operation, so in recent years it has become common to increase performance by increasing the number of cores instead of the number of clocks, and most of today's CPUs are is becoming multi-core.
In other words, "prioritize single-core performance" in this example can be thought of as giving priority to high clock speeds per core in the CPU, rather than parallel computing capability with multiple cores.
In addition, the above-mentionedCONSIDERATIONS FOR SYSTEMS RUNNING DIANAhas the following description, and you can see that single-core performance is required because most of the analysis is performed sequentially rather than in parallel.

Adding additional cores helps to reduce the analysis time but since a substantial part of the analysis is executed sequentially instead of parallel the primary focus for improving performance should be to improve the single core performance of the system.
