Abstract:Some general problems in mesh generation were discussed,the demands of mesh gener-
ation were expounded,the mesh generation methods were introduced,the mesh generation algorithms
in last ten years were retrospected and their advantages and disadvantages on
the requirements of practical engineering calculation,the authors brought up the mesh quality demands
and decision index,explored the mesh quality optimization,introduced the preprocessors and their ap-
plications of mercial softwares,then gave out several practical examples of the mesh genera-
last,the trends of mesh generation were also presented.
Key words:mesh generation;finite element;algorithm;mesh quality;decision index
