Study on 3DEXPERIENCE Platform to FLAC3D Model Conversion based on 3dxml Format
In order to study how 3DEXPERIENCE and FLAC3D work together effectively as design tools in different fields,a conversion method from geometric model to mesh model is proposed based on 3dxml file features and mesh model generation technology.The method includes file for-mat parsing and data structure mapping to ensure that the geometric shapes and attributes in the 3DEXPERIENCE platform model can be correctly stored;using mesh generation technology,a mesh model that meets the FLAC3D simulation requirements is generated,and a custom program is written to complete the conversion function.In practical applications,taking a water conservancy project dam and a large-volume cavern as exam-ple,the geometric model of the 3DEXPERIENCE platform is successfully converted into a mesh model of FLAC3D.The results show that the con-version method can realize the functions of parsing CAD geometric models,data structure mapping,generating tetrahedral mesh models and saving files,and complete the conversion from 3DEXPERIENCE platform to FLAC3D model,thereby simplifying the workflow of water conservancy project design and scientific research;compared with 3DEXPERIENCE's mesh generation program,the conversion using the self-compiled program can perform mesh encryption in local areas,increasing the number of nodes and units by nearly 5 times,which is more suitable for numerical simula-tion calculations.The study results have important practical value for the collaborative work of CAD/CAE tools and improving the efficiency of wa-ter conservancy project design.
