Product development begins with concept design, and design phase proceeds in the order of functional design and detailed design. As many design changes occur later in the design phase, rework will occur and the development-cost will increase, so front-loading with performance assessment in the first half of the design phase is critical.

Simplification of solution modeling by beam element has been used for a long time, but it is not versatile and it is difficult to cope with large deformation and crash. To solve this issue, JSOL has developed a beam material model that takes buckling deformation into account (planned patent application), and has built a new reduction modeling technique that takes beam element's simplified method into extension. This allows for impact strength assessment of the device during the initial design-phase concepts. In addition, the "Part-specific Reduction Modeling Method (patent-pending)" developed by JSOL realizes a hybrid model that combines a detailed shell-model with a simple beam model. J-SimRapid reduction model supports efficient product-development not only in the early stages, but also in the functional and detailed design in the second half of the design.

In concept design, it is required to examine component shapes and sets necessary to satisfy product performance in a short time.
The new reduction model offered by J-SimRapid enables the following:
- Lower computing cost
- Easy to change the cross-sectional shape
- Easy to add and erode components

The cross-sectional shape of beam created by the J-SimRapid is set by integration point, so you can change the cross-sectional shape without meshing. With this technology, speedup of the optimization calculation of the cross-sectional shape is realized.
In addition, the "Part-specific reduction modeling method (patent-pending)" developed by JSOL creates a beam model for each part, which facilitates addition and erode of parts.
