| Abstract: | The adaptive remeshing technique for quadrilateral elements consists of modules the
trigger of remeshing, the new mesh generation, adaptive refinement and interpolation
of field variables. The new adaptive mesh genemtion is the key problem. First, a
coarse mesh is created by using "loop algorithm". Subsequent local mesh adaptive
refinement is performed based on effective strain. Finally, a typical example of upset-
ting is given to test efficient of techniques, from which it is verified that the remeshing
algorithm developed here exhibits good performance and has high accuracy. |
