Licensing for CRUNCH CFD is set up so that calculations for large scale problems can be accomplished in a cost effective manner. Each license has a flat annual price that allows unlimited number of processors to be used per job. Custom packages for smaller time periods are also available as are volume discounts for multiple licenses. Pre- and post-processing utilities do not require licenses to run (unlike some other CFD packages) and maximize productivity by allowing users to either set-up or post-process other jobs while the licenses are being used to run simulations.
