A Novel Meshing Algorithm for Dynamic Finite Element Analysis
Integrated Manufacturing Technologies Institute, National Research Council Canada.
2003 (English)In: Precision engineering, ISSN 0141-6359, E-ISSN 1873-2372, Vol. 27, no 3, p. 245-257Article in journal (Refereed) Published
Abstract [en]

This paper describes a new algorithm to handle problems in dynamic finite element analysis and run-time simulation, where mesh re-generation or dynamic adjustment is required. Based on a concept called coded box cell (CBC) substitution, this algorithm can be applied to both initial mesh generation and dynamic mesh adjustment along the border zones of multiple primitives that form an entire model. During the initial mesh generation, appropriate labels are assigned to the nodes and the faces of each finite element. These labels are used to facilitate decision-making in dynamic mesh adjustment. A mapping technique is adopted to transform curved surfaces to plain surfaces for the ease of automatic mesh adjustment while still using the same algorithm. The results of a case study show that a finite element mesh can be adjusted dynamically and locally around its border zone; and the algorithm can be utilized effectively to simulate the thermal behavior of a device under real operating conditions.
