vinerm will become famous soon enough
Do you want these for post-processing or do you want to access these in a UDF? For post-processing, just issue the following command in Fluent and then run at least 1 iteration. Then, these will be available in Contours, Vectors, etc. Do note that these are available only within Fluent and not in CFD-Post (in case you are using Workbench).
