For the past few years I have been using OpenDX to post-process the results of a 3D radiation transport code. I am concerned that with expected increases in the size of the analysis models I may soon reach a point where OpenDX may not be a viable option for post-processing.
As a hypothetical example, consider a 3D model with 200,000,000 mesh cells. (This is significantly larger than current models, but a realistic projection based on trends in computer resources.) The model geometry is based on a structured rectilinear grid which can be represented as a product array of 3 vectors (i.e., the X, Y, and Z mesh spacings). Each mesh cell has a connection-dependent value (byte or integer) which represents the material composition in that cell. Each cell will also have one (and possibly more) position-dependent values (real) which represent an analysis result. For typical visualizations, the composition data is processed using Color --> ShowBoundary --> Image, typically after passing through an Include module to exclude certain materials from the image. The real data is generally processed using Isosurface, with the Isosurface output being Collected with the ShowBoundary output. It seems to me that I have two options to deal with expected model size increases: 1) Hope for a 64-bit version of OpenDX, preferably one which will run in parallel on distributed memory systems, or 2) Explore other data visualization options Any suggestions from those of you who have more experience in this area?
