A simple and efficient algorithm of automatic mesh generation for a general plate and frame structure with holes

摘要

The creation of the geometry for a general plate and frame structure with holes is discussed, and a simple and efficient algorithm of the mesh generation of the structure is presented for structural and thermal analysis. Mainly quadrilateral elements are generated and triangular elements are partially used in transient regions on the surface of the structure. For the frame parts of the structure, beam elements are generated for structural analysis and bar elements for conduction, convection and radiation for thermal analysis compatible with adjacent plate elements. A simple method to generate nodes at arbitrary point of the structure is also described.
