Efficient simulation modelling technique using automatic mesh and contact interface generation

Computer-Aided Engineering (CAE) users often follow traditional meshing and contact generation processes, which are time-consuming, repetitive, and heavily dependent on user experience and perspective. The method described herein presents a system for generating a mesh and contact interfaces that ensures standardized and consistent output for a model. The system stores multiple mesh configurations, each containing a set of predefined geometric features to create standard meshes for users. The process begins by receiving data for a CAD model of an object and capturing user input through a graphical user interface. Users specify several parameters, including the desired body type, global mesh size, and a selected mesh configuration from the available options. Using these inputs, the system generates a mesh for the model, incorporating the selected mesh configuration’s geometric features along with the specified body type and size. The contact generation process offers several key features for enhancing FEA simulations. It classifies contact types based on input and optimizes contact parameters. Interactive visualization allows users to review and adjust contact definitions. Batch processing supports efficient handling of large assemblies. This combine method ensures that process is efficient, flexible, and customizable for different user needs while maintaining consistency across various models. Additionally, the approach supports customization by allowing users to select the configuration that best suits their modeling requirements.
