Shao-chunChen, Dong-yangShi, Guo-biaoRen · Acta Scientiarum Naturalium Universitatis Sunyatseni · 2004
The well known Wilson's brick is only convergent for regular cuboid meshes. In this paper a quasi-Wilson element of three dimension is presented which is convergent for any hexahedron meshes. Meanwhile the element is anisotropic, that is it can be used to any flat hexahedron meshes for which the regular condition is unnecessary.
