If CAD data is not properly managed, it can take a long time to search for the desired CAD data. Even if the search time for each instance is short, when many people search multiple times, the total wasted time becomes enormous. Why is it not properly managed? The reasons are, as expected, either that management rules have not been established, there are problems with the management rules, or the management rules are not being followed. If there are no problems with the management rules but they are not being followed, we can only ask for compliance. If that is not the case, there may be issues with the management rules, including the possibility that they have not been established. One obstacle to establishing management rules is the resistance to changing the way work has been done until now. Everyone tends to be reluctant to change familiar methods. However, if the current way of working is an obstacle to properly managing CAD data, shouldn't we change the way we work? So, how should we change our work methods? The suggestion is to align the work methods with CAD data management software.

**Case Overview** ■Product Name: Simcenter Femap with Nastran ■Analysis: Nonlinear Static Analysis ■Industry: Mechanical Components Buckling is a deformation that exhibits very strong nonlinear characteristics. When buckling occurs, the strength and stiffness of the structure decrease sharply, leading to instability. Thin-walled frame structures, like the one shown in the right diagram, have many failure modes, and buckling can cause extremely large deflections in the frame. Since part of the model may transition from an elastic state to a plastic state and back from plastic to elastic, the analysis becomes quite complex. This analysis example presents the nonlinear analysis results for the elasto-plastic buckling problem of frame structures. □ For other features and details, please refer to the catalog.

**Case Overview** ■Product Name: Simcenter Femap with Nastran ■Analysis: Linear Static Analysis, Modal Analysis, Frequency Response Analysis ■Industry: Other A cantilever is a sensor that detects the interaction force between the probe and the sample in an atomic force microscope by measuring changes in displacement or resonance frequency. It is applied in fields such as precision machining and measurement of nanostructures. Since the detection sensitivity is determined by the mechanical properties of the cantilever, it is very important to determine those properties.

**Case Overview** ■Product Name: Simcenter Nastran ■Analysis: Modal Analysis of Natural Frequencies ■Industry: Other The vibration characteristics of rotating bodies exhibit whirl motion due to centrifugal force, tilt vibrations, and gyroscopic effects as the axis rotates, resulting in changes in eigenvalues. When the direction of rotation and whirl motion align, it is referred to as forward whirl; when they are opposite, it is called backward whirl. When the rotational speed matches the eigenvalue of the axis, the amplitude of the whirl increases, leading to instability in the rotating system and potential damage to components. The speed at this point is referred to as the critical speed. In this analysis, modal complex eigenvalue analysis was conducted for specified rotational speeds to investigate the whirl modes induced by rotation, changes in damping, and critical speeds. □ For other functions and details, please refer to the catalog.

**Case Overview** ■Product Name: Simcenter Femap with Nastran ■Analysis: Nonlinear Static Analysis ■Industry: Mechanical Components Plastic processing primarily involves shaping through contact between tools and workpieces. Among these, the method of forming bottomed containers from metal sheets using a punch and die is called deep drawing. Various factors such as the structure and material of the mold, the shape of the blank, and friction conditions influence the process, causing changes in the stress distribution in different parts of the blank during forming, which can lead to issues like cracking and wrinkling. This analysis example introduces a case of deep drawing for a rectangular box-shaped container. The initial shape of the blank is 200x200 with a thickness of 0.82mm. The die is a rigid flat plate with a square hole measuring 102.5x102.5 and rounded corners with a radius of 10mm.

**Case Summary** ■Product Name: Simcenter Femap with Nastran ■Analysis: Modal Analysis ■Industry: Railways and Shipping Since railway vehicles operate in a coupled manner, it is necessary to analyze the motion characteristics of the entire train when considering the dynamics of the vehicles. To accurately predict the vibrations generated in various parts of the moving vehicles, a vehicle simulation using a FEM model that closely resembles the actual structure, rather than a uniform beam or equivalent plate structure, is required. On the other hand, such analyses heavily depend on the computational environment, model creation, and result display capabilities, necessitating parallel computing solutions and efficient pre/post-processing software. In this example, a vehicle body was created using Simcenter Femap, and a modal analysis of a 10-car train model was conducted using Simcenter Nastran to determine the natural frequencies up to 20 Hz.

**Case Overview** ■Product Name: Femap Thermal ■Analysis: Thermal Analysis ■Industry: Mechanical Components Modeling can be challenging when it comes to thermally connecting components due to thermal resistance from contact or thermal conduction at adhesive points. By using the thermal coupling feature, it is possible to define conductive conductance, thermal conductivity, or thermal resistance values between distant meshes that do not share nodes, allowing for thermal coupling between these meshes in calculations. This is an excellent feature that automatically considers the positional relationships of elements and allocates the degree of thermal coupling for each element. In this analysis case, we will analyze the temperature distribution due to heat generation from a chip in a structure consisting of four types of components: chip, substrate, edge guide, and case. The adhesion between the chip and substrate, as well as the edge guide that connects the substrate and case, were modeled using thermal coupling. □ For other functions and details, please refer to the catalog.

**Case Overview** ■Product Name: Femap Thermal ■Analysis: Thermal Analysis ■Industry: Other In this analysis example, we conducted a thermal radiation transfer analysis within a container composed of multiple radiation areas. In this case, the radiation areas consist of three regions: the interior of the container, which includes the heat source, heated surface, and inner wall; the space between the inner and outer walls; and the area from the outer wall to the environment. The calculation of the form factor is known to be time-consuming due to the exhaustive element-to-element calculations, resulting in a large matrix size. Femap Thermal utilizes the Hemicube method with OpenGL to process the time-consuming form factor calculations quickly.

**Case Overview** ■Product Name: Simcenter Femap with Nastran ■Industry: Mechanical Components The super-element feature of Simcenter Nastran reduces computational load by dividing large models for analysis or by simplifying parts of the model (external super-elements), thus making the analysis model smaller and shortening computation time when changes are made to other parts. In this case, we validated the analysis accuracy and evaluated the reduction in computation time by simplifying the unchanged boss section as an external super-element and analyzing it in conjunction with the mesh model of the blade section during the eigenvalue design of the fan blades. This method saves computation time, especially in design phases where performance evaluations and repeated calculations at the component level are common, and the more unchanged parts there are, the more significant the benefits. Additionally, by converting in-house component models into super-elements and providing them to other companies, the shapes can be treated as black boxes, thus enhancing information security. □ For other features and details, please refer to the catalog.
