Groundwater Resources Evaluation Based On The Techniques Of Generating FEM Mesh Automatically

This paper discusses the importance of Groundwater Resources Evaluation ,its history ,present & developing tendency. After introducing the main approaches briefly , this paper summarizes and contrast them .It lay emphasis on the research of Galerkin FEM equations for multiaquifers and its solution, and on the research of basic ideas and implementation of visual mesh auto-generation 。With an in-depth study on automatic mesh generation dividingtechnology of finite element, computer image processing techniques and visual scientific calculation technology, and under thebased on WINDOWS 2000 platform, we work out the foreground programs using Visual Basic 6.0 from Microsoft ,which possesses friendly programming environment and abounding graph function, while the background programs are accomplished using the powerful function of data base and chain table of Delphi 6.0 from Borland. We develop uniquely steering & visual function software, it can create topology structure of the system and DXF files which can communicate with AUTOCAD.At last ,taking Kash as an example ,it evaluates this area's Groundwater Resources ,and give out three predicting projects by making use of visual FEM mesh generation software and the numerical solution of Galerkin FEM equations for multiaquifers .
