Converging solution depends on lot many factors like inlet and outlet conditions, mdoels used, mesh density etc. 


If you have a car in tunnel, you will net prism plus tet mesh. As 512K is the limit, you can consider reducing you problem size by considering symmetry. 


The sizes will depend on the features in your geometry you want to retrain.
