Abstract

Abstract

Meshing is the most important part of the finite element modeling and analysis process, and it also has the largest workload, which directly affects the accuracy and time of the finite element analysis. Based on the research of adaptive meshing and finite element discrete errors, three-dimensional human body models of different complexity are established in the environment of high-voltage power transmission fields. By comparing the results of the electric field simulation between the adaptive meshing of the human body model and the manual meshing, the trend of energy error changes is analyzed, so as to guide the establishment of the human body model and the setting of the optimal mesh size.The research results have certain reference significance to the optimization research of other finite element splitting schemes.
