An Easy Windows Graphic Interface For 3-D Electrical Geophysics Modeling

The finite element method is a very powerful tool<br>for modeling complex problems in physical science,<br>engineering and geophysics. However, for three<br>dimensional analysis, the arduous pre-processing<br>stage which consists of supplying the data for the<br>mesh and the physical properties for each element is,<br>certainly, a weakness of the method. In order to<br>handle this disadvantage, we developed a simple<br>Windows graphic interface for entering the<br>information of the physical properties across the mesh<br>at no great pains. We use the 3-D Resistivity and IP<br>modeling problem to show how the proposed graphic<br>interface facilitates the access of finite element data.<br>Apparent resistivy and PFE pseudo-sections at 10<br>parallel survey lines, one dipole unit apart, are<br>displayed graphically to exhibit the output graphic<br>interface that was also developed for presentation of<br>the modeling results.
