Achieve design efficiency on CAE! Significantly reduce man-hours by effectively utilizing existing models.

At IDAJ, we propose to enhance design efficiency on CAE by effectively utilizing Abaqus models. By making effective use of existing models, we can significantly reduce the man-hours required for preparing parametric model creation. When integrated with modeFRONTIER, we provide designers with "hints" for optimization to address the multi-objective optimization problems faced in design development. 【Features】 ■ Import Abaqus inp files and quickly modify shapes ■ No need to regenerate the mesh or reset boundary conditions after shape modification ■ Parameterization of shapes such as hex-mesh models that are difficult to generate automatically ■ No need for complex script preparation to build optimization systems ■ Support for optimal design considerations using cutting-edge optimization methods and experimental design techniques *For more details, please refer to the PDF materials or feel free to contact us.

Achieve design efficiency on CAE through effective utilization of the Abaqus model!

By using the high-end mesh morphing program 'DEP Mesh Works/Morpher' to modify the shape based on the mesh of the Abaqus model, and by parameterizing it to build automation and optimization systems, we can effectively utilize existing models and significantly reduce the man-hours required for preparing parametric model creation. Furthermore, by integrating with the multi-purpose robust design optimization support tool 'modeFRONTIER', we provide designers with "hints" to understand the phenomenon of "what design is optimal and why" in response to multi-objective optimization problems faced in design development, such as weight reduction, minimum stress, and minimum displacement. *For more details, please refer to the PDF materials or feel free to contact us.

Integration of implicit and explicit methods. For elucidating a wide range of phenomena such as heat, electricity, magnetic fields, and fluids.

In nonlinear structural analysis, the three key nonlinearities are material, geometry, and boundary conditions. In recent design practices, there is a necessity to consider contact in assembly components using complex material models. Abaqus can accurately model not only classical metal material constitutive laws but also failure models due to rate dependence and polymers such as rubber and resin. Additionally, the innovative formulation of surface-to-surface contact achieves more robust convergence and higher analysis accuracy compared to other structural analysis tools. The general contact feature requires minimal user setup, significantly reducing the time needed to define contact in complex assemblies found in automobiles, aircraft, consumer electronics, and portable electronic devices.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

● The production time for cast prototypes can be shortened! Since model making is not required, the production time for prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! Different products, such as similar shapes or varying dimensions, can be molded at the same time in one molding process. This allows for the verification of multiple types in a short period.

Last month, we held a spring safety conference hosted by our company. We have compiled the details and atmosphere of the day into a PDF. We would appreciate it if you could take a moment to read it.
