Convective term evaluated at time n+1/2 -- CFD Online Discussion Forums

February 12, 2007, 15:22	Convective term evaluated at time n+1/2	#1
Lionel S. Guest Posts: n/a	Hi all, I found an interesting article, but I would like some help to understand it. At bottom of page 10 of http://txspace.tamu.edu/bitstream/19...-CPSC-Wang.pdf It seems that convective term (and also term in alpha) is evaluated at time step n+1/2 (formula 1.4) from values of time n and then used as a known value at time step n+1 (formula 1.5) to get a linear equations (1.6). As I understand, it means that convective term remains constant from one iteration to another, espetially if we are solving a steady-state problem (I would remove term in DeltaT). Well, I guess that I missed something. How do you understand it ? Thanx, Lionel
