Thanks Benny. This type of feedback is highly appreciated. I'll merge your example in just as soon as I can. An improved test method is also probably in order rather than rudimentary point values. Any ideas? I actually have a more extensive flow problem that I'm hoping to include in FiPy in the

Hi, I am doing a flow field calculation like http://www.ctcms.nist.gov/fipy/examples/flow/generated/examples.flow.stokesCavity.html However, I obtain spurious oscillations for the pressure solution. Patankar in his works is very clear that a staggered grid should be used for the SIMPLE
