Abstract
A method of constructing surface element layers for improving boundary shape of a hexahedral mesh used in finite element analysis comprises constructing a core mesh by superimposing a regular grid on a region to be meshed and removing external elements and external nodes of the region to be meshed; amending the core mesh to have a boundary shape similar to that of the region to be meshed by repositioning nodes on the boundary of the core mesh; constructing imaginary thin surface element layers on a boundary surface of the amended core mesh; and performing a mesh smoothing on the imaginary thin surface element layers.
