Automatic finite element mesh generation for industrial use

Joachim Wendt, Anu Piira

Research output: Book/ReportReport


The use of finite element analysis methods is increasing in all kinds of engineering applications. Numerical modelling of different processes sets different demands on analysis models and thus also on finite element mesh generation. For this reason different approaches to automatic mesh generation are described in this booklet. First, the methods usually used for the automatic generation of tetrahedral and hexahedral meshes are reviewed. In casting applications, surface respecting algorithms are preferably used. These algorithms may start from polygonially described object surfaces and then use cutting techniques as in the case of the DIDO mesh generator. Other approaches combine different methods such as octree methods together with the advancing front method. Also slicing methods that are used to reduce the 3-dimensional meshing problem to several 2-dimensional problems are used successfully. On the other hand, special processes like investment casting in ceramic shell moulds suggest special techniques for a lifelike enmeshment of the ceramic shell.
