This section has been divided to two parts: The first for highly automated-integrated software systems which can work directly with native solid modeler's cad data and do the all job - preprocessing, solving and post processing in a single easy to use gui environment. They are for non-CFD specialists, typically design engineers. But they can not give you analyst level control and results for your problems. The second contains high-end cfd solvers with latest available technology options today which require good knowledge of fluid dynamics as well as experience in using cfd. With these packages you may need 3rd party software for preprocessing the problems and postprocessing to evaluate the results.
