## Main Question or Discussion Point

**navier-stokes smoothness problem almost solved**

Penny Smith has made progress with showing that smooth conditions exist for all time in a domain for the Navier Stokes equations

http://notes.dpdx.net/2006/10/06/penny-smiths-proof-on-the-navier-stokes-equations/

However a flaw was found in the mathematics - hopefully it can be sorted out soon.There's still the problem though of finding actual solutions to the equations!

Thanks for the info on control volume.I was just wondering if in reality there

is a real,if very small size,to the differential element.
