We have developed an FEM tetrahedral-mesh generation technique for re-using an existing mesh in order to generate a new mesh after a change in 3 D-CAD data during parameter survey. Up to now, all meshes for updated 3 D-CAD data have been generated manually; however, the developed technique automatically uses a volume mesh and a surface mesh extracted from the existing mesh. It does this by recognizing the difference in the 3 D-CAD data before and after it is changed. As a result, mesh generation time is not wasted; that is, after the first mesh generation, the next generation times are shortened to 1/5 of the initial time.
