Figures show the edges generated in hot and cold forging, respectively. It should be emphasized that a detailed description of the workpiece geometry is a very important part of MFS if one is to obtain the sort of accurate results shown in the figures. The mesh system shown in Figure (b) describes the chamfered corner clearly and accurately with the limited number of tetrahedral elements. Description of such corner with greater number of elements should be avoided because frequent remeshing due to small volume of an element leads to greater numerical smoothing.
