Examples of results of the dolfyn version of September 2004:

Turbulent flow around a car at 108 km/hr (109 kB). auto
Turbulent flow through a channel (69 kB). kanaal
A stagnant flow is a good test because the pressure rise can be calculated by hand (Bernoulli) and the isobars are circles (86 kB). stuwpunt
This is a simple test with a bad mesh('rough grid'). This example can be found in: P. Wesseling, 'Principles of Computational Fluid Dynamics', chapter 13.6, fig. 13.12 (35 kB) test
