OpenDX is a general-purpose visualization package. This is due to the generality of the data model, and the flexibility of the visual programming language. OpenDX is not optimized for any particular branch of science. Thus, while you can use OpenDX very effectively to visualize the output of many different types of experimental or collected data sets or computer-generated simulations, OpenDX does not have built-in functionality to perform, say, computational fluid dynamics or finite element analysis operations. (You could add such operations if you are inclined, but they are not built-in). We have made wonderful visualizations of the outputs from Fluent (fluid flow analysis software), PATRAN (finite element analysis software), ArcInfo (geographic information systems software), and so on, but OpenDX itself has no particular features that make it a CFD, FEA, or GIS package, any more than do C or FORTRAN as programming languages.
