RE: Convection solutions

[Damm, Edward F. (E. Buddy)]

Sorry,  Hope the attached clarifies it.  The second to the last equation is what I am talking about.  The stuff before leads up to it.  The term that is not in the original reference, but that I added per our discussion was the 1/uc.   Buddy From: fipy@nist.gov [mailto:[EMAIL PROTECTED] On Behalf Of Daniel Wheeler Sent: Thursday, April 27, 2006 1:10 PM To: Multiple recipients of list Subject: Re: Convection solutions I am not sure what we are talking about here. Can you include some code or some maths to clarify? You can use tex for the maths to be clear, otherwise just include the code. On Apr 27, 2006, at 12:55 PM, Damm, Edward F. (E.
