Abstract

Geometry preparation and construction of high-quality finite element mesh is one of the key steps of analysis using computer aided engineering tools. Therefore, rational application of tools used for creation of finite element models is useful skill that determines the efficiency and productivity of numerical analysis and also effects the accuracy and time required for getting the result.The capabilities of the Meshing Toolbox of FEMAP v. 10.2 finite element software, which are used for preparation and creation of finite element models of the objects with complex geometry, are described in the paper. The goal of the work is to build high-quality, mapped meshes for objects with complex geometry and reduce the dimension of the finite element model. Methods for improving the quality of the mesh in the local areas of a model with complex geometry and reducing the dimension of a model are considered using several practical examples. A useful and practical feature of the tools is that automatic remeshing is provided in case of changing the basic geometry. The effective application of tools for preparation and creation of finite element models allows you to build mapped hexahedral meshes and thereby significantly reduce the dimension of finite element models, increasing their computational efficiency. Depending on the degree of complexity of the model, the number of elements in the model decreased by several times, and the number of nodes — on average, by 20%. The issue of applying the described approach and tools is especially concern for large models and in case of limited computational resources.
