Formatted Abstract/Summary The relevant progress of mesh generation especially in the engineering field is firstly briefly listed and then the possibility for extending its application to geosciences field is discussed. For geosciences, the available input data are normally a large quantity of point data in the 3D space rather than the defined shapes and dimensions with reasonable tolerances provided by the industrial designers, thus quite different from the engineering case. To deal with such complicated data, an unstructured mesh generation tool based on the Delaunay algorithm is developed
    (1) to accurately represent the complex geologic structure and stratigraphy and to automatically generate the unstructured meshes for the further numerical modeling of such as groundwater resource development and geothermal reservoir system using our finite element code;
    (2) to visualize/mesh the ruptured zone with the micro-seismicity data recorded during a hydraulic stimulation process, such as in a Cooper Basin geothermal reservoir;
    (3) to integrate with the our finite element code for an adaptive nonlinear finite element analysis of various complicated cases which require the adaptive remeshing for a more accurate and reliable results with reasonable computational cost.
The related application examples will be presented to show its efficiency and usefulness.
