http://www.gidhome.com/%|%GiD%|% is a universal, adaptive and user-friendly pre and postprocessor for numerical simulations in science and engineering. It has been designed to cover all the common needs in the numerical simulations field from pre to post-processing: geometrical modeling, effective definition of analysis data, meshing, data transfer to analysis software, as well as the visualization of numerical results. GiD embeds a Tcl interpreter for script access to the program API. <> Mathematics
