Case No.PC-9133B2A customer who saw this asked us about a PC for the purpose of numerical analysis research in metal additive manufacturing technology.
You are considering a workstation for coupled research of discrete element method (DEM) and computational fluid dynamics (CFD), and would like a machine configuration suitable for numerical analysis.
The specific conditions are as follows.
・Storage: SSD NVMe compatible 1TB x 2 units and HDD 4TB x 1 unit
・OS: Windows
・Software used: YADE, OpenFOAM, FLOW-3D, Thermo-Calc, MICRESS
・Others: Some software is assumed to be used in a virtual environment.
Based on the content of the consultation, we proposed the following configuration.
The Ryzen Threadripper 9133 series used in case study No.PC-2B3000 ended in the form of being integrated into the higher lineup Ryzen Threadripper Pro.Therefore, in this example, the configuration is equipped with a 5000-core model of the Threadripper Pro 32 series.
In the same price range, the Xeon 2 CPU configuration, which is a CPU for servers, is also an option, but the Threadripper Pro configuration improves the base clock and you can expect single-core performance.
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 metal additive manufacturing?
Metal additive manufacturing is a technology that uses a 3D printer to create three-dimensional metal parts by melting and layering metal powder.It is suitable for prototype development because parts of any shape can be manufactured in a short delivery time.In addition, the loss of materials is small and the cost performance is excellent.It is used in a wide range of fields such as aerospace, medicine, and machinery, and it is possible to build a system suitable for mass production.Because it is possible to form parts directly from digital data, it is easy to integrate AI and IoT into conventional production processes, and it is attracting attention as a next-generation production technology.
・What is YADE?
YADE is an open source simulation software based on the discrete element method.Collision and contact between particles can be simulated, and various phenomena can be reproduced.It supports two types of collision detection algorithms: the high-speed Grid method and the highly accurate direct method.In addition, large-scale simulation is possible with parallel computing using OpenMP.It is used as a simulation tool for research and development, mainly in the fields of civil engineering, geotechnical engineering, and material engineering.
・What is OpenFOAM?
OpenFOAM is open source CFD software.Based on the finite volume method, it supports unstructured grids.A wide range of physical models and numerical methods enable analysis from fluid flow to chemical reactions and heat transfer. It supports MPI and OpenMP and is suitable for high performance computing (HPC).Software that is widely used in research and development and education, mainly in universities and research institutes.
・What is FLOW-3D?
FLOW-3D is a commercial CFD software.It uses the finite volume method and supports unstructured meshes.Analysis centered on the field of hydraulics is possible, and it supports multi-phase flows and complex fluid-structure interaction problems.Meshes can be created intuitively with a dedicated mesher.It has various physics models and advanced post-processing functions, and the results can be easily visualized.In addition, parallel processing enables analysis of large-scale problems.We provide solvers that support a wide range of problems from general flow to advanced problems.
・What is Thermo-Calc?
Thermo-Calc is a commercial phase equilibrium calculation software.Phase equilibrium calculation is possible based on a database centered on steel materials.It also supports calculations under high temperature and high pressure conditions.In addition to phase equilibrium, diffusion and solid phase transformation can be simulated. Web functions and APIs also support linkage with other software.In addition to being able to visualize the results in table format and graph format, teaching materials are also provided and used for human resource development.
