Description

Preprocessing Automation Program and Device The disclosed invention relates to a preprocessing automation program and apparatus for performing structural analysis tasks according to an automation program in the CAD-based FE (Finite Element) MESH stage. Finite Element Analysis (FEA) is a simulation method used to predict the performance of complex structures or systems. It is utilized to evaluate stress, deformation, heat distribution, and fluid flow in structures, and is essential for cost reduction and safety verification in product design and engineering processes. In the preprocessing step for performing conventional finite element analysis, to generate a mesh, the user can configure the basic geometry of the CAD model, directly remove or simplify unnecessary details, specify physical properties of the material (e.g., density, elastic modulus, thermal conductivity, etc., physical properties required for analysis), specify boundary conditions and load conditions such as fixed points, force, pressure, and heat required for analysis, and set the mesh size and element type to generate an FE mesh. However, if the mesh generation and configuration are not performed correctly according to this user-selected preprocessing step, the analysis results may be inaccurate or fail to converge. Given that the preprocessing step is considered one of the most critical stages of FEA, accurate and reliable standards must be applied to mesh generation, quality review, and modification.

FIG. 2 is a schematic diagram showing the configuration of a pre-processing automation device according to one embodiment. FIG. 3 is a diagram schematically showing the configuration of a toolbar according to one embodiment. Throughout the specification, the same reference numerals refer to the same components. This specification does not describe all elements of the embodiments, and general content in the art to which the disclosed invention pertains or content that overlaps between embodiments is omitted. The terms 'part, module, component, block' used in the specification may be implemented in software or hardware, and depending on the embodiments, a plurality of 'parts, modules, components, blocks' may be implemented as a single component, or a single 'part, module, component, block' may include a plurality of components. Throughout the specification, when a part is described as being 'connected' to another part, this includes not only cases where they are directly connected but also cases where they are indirectly connected, and indirect connections include connections made via a wireless communication network. Furthermore, when it is stated that a part 'includes' a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components. Throughout the specification, when it is stated that a component is located 'on' another component, this includes not only cases where a component is in contact with another component, but also cases where another component exists between the two components. Terms such as "first," "second," etc., are used to distinguish one component from another, and the components are not limited by the aforementioned terms. Singular expressions include plural expressions unless there is an obvious exception in the context. In each step, identification codes are used for convenience of explanation and do not describe the order of the steps; the steps may be performed differently from the specified order unless a specific order is clearly indicated in the context.
