Robustness represents the strength (small variation) against changes in the environment or situation and is an important evaluation criterion that affects yield in actual production. "AMDESS" can provide a virtual variation to the approximation model, allowing for the evaluation of this robustness.

The displacement solution of static stress analysis or the temperature solution of steady-state heat conduction analysis rarely produces errors as long as the shape is represented accurately; however, there are problems where the errors can become significant. When the original shape does not match the voxel pitch, discrepancies in the shape occur. Therefore, to achieve better accuracy in the analysis, it is necessary to refine the mesh, which increases the model size. Here, we will introduce a case study applying FCM as a solution to this issue.

Finite element analysis using voxels has the advantage of being easy to operate, fast, and not incurring human costs; however, it also has the disadvantage of causing stress wave phenomena. To eliminate this disadvantage, we will apply the Finite Covering Method (FCM) to improve analysis accuracy. Here, we will verify how the analysis accuracy improves by using the Finite Covering Method (FCM) while changing the mesh size and comparing it with the Finite Element Method (FEM).

Generally, the measuring instruments used in reverse engineering can be broadly classified into devices that measure the outer surface and those that measure not only the outer surface but also the interior of the object. In the former category, laser scanners and digitizers are practical, while in the latter category, X-ray CT scanners have been developed. One advantage of using X-ray CT scanners is that they allow observation of the internal condition without destroying the product. Here, as an example of non-destructive testing, we will introduce a case of observing the state of cavities (voids) that occur inside a product.

In strength design, stress serves as an important guideline. When conducting strength assessments based on stress, it is necessary to vary the evaluation stress values according to different parts, rather than relying solely on the maximum value. In such cases, by specifying constraint stress values for each region, it is possible to obtain an optimal shape that constrains stress at multiple evaluation points and all locations. This time, we will introduce an optimization case with different stress constraints applied to various parts of the model.

Topology optimization is a method for determining the necessity or redundancy of materials (member layout) that contributes to lightweight and high-rigidity product design, such as seeking structures that maximize rigidity under a certain weight limit. While it allows for significant structural changes compared to the initial structure, it can also result in outcomes that are difficult to manufacture or lead to complex structures with high manufacturing costs. To avoid such situations, the topology optimization in 'OPTISHAPE-TS' utilizes a topology density variation limitation feature, enabling optimization while satisfying manufacturing requirements.

In mechanical components with mechanisms like links, the arrangement of surrounding parts may change depending on their operational status, which can also alter the mechanical conditions experienced by the component. When designing such mechanical components, it is necessary to consider multiple mechanical conditions simultaneously. "OPTISHAPE-TS" provides various functions for optimization that take these multiple mechanical conditions into account at the same time. Here, we will introduce a method for shape optimization that considers multiple mechanical conditions simultaneously by using several reduced-order models and switching between them during analysis.

Weld lines can become an issue of strength and design depending on their occurrence location. To control the occurrence location of weld lines, it is generally known that changing the gate position, resin temperature, mold temperature, and holding pressure can be effective. In this case, we optimized the gate position to prevent weld lines from occurring in specified locations by integrating the general-purpose parameter optimization software "AMDESS" with the plastic injection molding CAE software "3D TIMON" developed by Toray Engineering Co., Ltd. As a result, by changing the gate position, we were able to shift the weld lines away from the specified area. [Results] - By changing the gate position, we were able to shift the weld lines away from the specified area. - The approximation of the objective function improved with each addition of the approximation accuracy enhancement proposal. - The effectiveness of the approximation accuracy enhancement proposals was also confirmed. *For more details, please refer to the PDF document or feel free to contact us.

The heat transfer coefficient depends on the surrounding environment and is not unique to the material, making it difficult to determine its value. If a heat transfer coefficient that can reproduce the measurement results can be identified, it is expected that good simulation results can be obtained for another model under similar conditions. In this case, the general-purpose parameter optimization software "AMDESS" was linked with "Nastran" to identify the heat transfer coefficient. As a result, the temperature at the evaluation points matched the target value within an error of 0.3%, and the heat transfer coefficients for each surface were obtained. 【Optimization Conditions】 ■ Design Variables - Heat transfer coefficients for each surface (h1 to h6) - Range: 10.0 to 70.0 [W/m2k] ■ Objective Function: Minimize the square of the error from the target temperature at each evaluation point = Bring the calculated temperature closer to the specified target temperature *For more details, please refer to the PDF document or feel free to contact us.

Press processing is a method used in the manufacturing of various industrial products, including automobiles. Since this press processing is often used for mass-produced products, it is desirable to thoroughly examine the processing conditions in advance using CAE. In this case, we optimized the processing conditions by linking the general parameter optimization software "AMDESS" with the explicit dynamic analysis software "Abaqus/Explicit Student Edition" (from SIMULIA, USA). We added recommended points based on the density of the data points we had previously investigated! We devised a way to avoid falling into local solutions. As a result, we achieved a maximum equivalent plastic strain reduction of 9% while satisfying all constraints.

This example introduces the integration of three software programs to reduce noise without compromising the electrical performance of a reactor. First, the general-purpose parameter optimization software "AMDESS" rewrites the VB script file of the 3D CAD software "SolidWorks" with trial dimensions and modifies the model dimensions. Next, the electromagnetic field analysis software "JMAG" communicates with "SolidWorks" to import the CAD model, performs meshing and analysis, and "AMDESS" extracts responses from the analysis results of "JMAG." As a result, starting from 30 samples using Latin hypercube sampling, a 31% reduction in sound pressure was achieved through six updates of the response surface. 【Optimization Conditions】 ■ Design Variables: Core dimensions D1 to D4 ■ Objective Function: Minimization of reactor sound pressure ■ Constraint Functions: Inductance greater than or equal to the initial value, core volume less than or equal to the initial value ■ Approximation Model: RBF *For more details, please refer to the PDF document or feel free to contact us.

We will introduce a case where warping was minimized by changing the thickness of solid elements. The analysis was conducted using the "basis vector method," which modifies the shape by moving the nodes of the finite element model without using CAD. Several patterns (basis vectors) of the desired shape were prepared from the initial model and combined. As a result of the optimization, the sum of squares of warping improved by 33% to 4.9480e-004 compared to the initial shape, and the maximum warping amount (mm) improved by 12% to 3.8607e-002.

After that, we add creases in the desired locations where we want corners to appear on the resulting surfaces. Additionally, various analysis surfaces such as cylindrical and planar surfaces are color-coded differently from the regular crease lines, making verification easy. 【Case Overview】 ■STL Model - Engine Block- ・Number of triangular patches: 492,886 ■Time taken for crease settings and analysis surface extraction: 4 hours (manual work) *For more details, please refer to the detailed materials available for download as a PDF or feel free to contact us.

As an example of shape optimization analysis for shell elements, we will focus on the reinforcing material of a square plate assumed to be the "center pillar" that constitutes the body of a car. "OPTISHAPE-TS" has a function that maintains the cross-sectional shape, allowing for the avoidance of complex cross-sectional shapes of the member during the shape optimization process. In the shape optimization process, RBE3 elements and their surrounding elements are automatically treated as spot welds, and constraints are set so that only rigid body motion is possible in those areas. In other words, while the position of the spot welds may move, the size and shape of the welds are constrained to remain unchanged.

We would like to introduce a case study on the optimization of fillet shapes aimed at stress reduction. Taking manufacturing requirements into account, we sought a shape that minimizes stress while maintaining a uniform R shape. As a result, due to the axial symmetry setting, we were able to alleviate stress while preserving symmetry. Typically, when evaluating and optimizing local stress, the shape does not remain symmetric. However, with "OPTISHAPE-TS," it is possible to optimize while considering symmetry, allowing for changes in shape while maintaining the symmetry of the R shape, as in this case. [Case Overview] ■ Analysis Model - Elements: Tetrahedral second-order elements - Number of elements: 220,782 - Number of nodes: 324,937 ■ Result: Stress was alleviated while maintaining symmetry due to the axial symmetry setting. *For more details, please refer to the PDF document or feel free to contact us.

By specifying this model as the "deviation designated area," we optimize the shape to ensure it does not extend beyond this region (does not deviate). As a result, we achieved a lightweight shape that meets various constraints without deviating from the specified area. Shape optimization is suitable for improving existing shapes, and by adding multiple constraints such as stress constraints and manufacturing requirements, it is possible to conduct more detailed examinations. *For more details, please refer to the PDF document or feel free to contact us.*

For rotating components such as wheels, advanced design is required that takes into account not only mechanical properties like rigidity, strength, and vibration characteristics, but also various manufacturing requirements and aesthetic considerations. Here, we present a case study of a motorcycle road wheel that was designed with manufacturing requirements in mind to achieve weight reduction. We established a Multi-Point Constraint (MPC) to maintain rotational symmetry while considering manufacturing requirements such as "the overall shape must be moldable" and "must have a certain minimum wall thickness." First, we created an initial model that is one-third periodic symmetric using rotational copying. Then, we added load and constraint conditions, outputting the data as Nastran data, and subsequently created and added the MPC for maintaining rotational symmetry using the post-processor TS Studio. As a result, we achieved approximately an 11% weight reduction while maintaining a rotationally symmetric shape.
