All,<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>I learned from the subroutines makeabf and makebdf in navier1.f that the time integration scheme for momentum equation is the AB-CN scheme, that explicit schemes for nonlinear and forcing term, and implicit ones for viscous term. The prefactors of those schemes are stored in AB() and BD() arrays. Now my question is, whether the temperature/scalar equations also use the same schemes as momentum ones and also share the same prefactors in AB() / BD() arrays.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>Any help is appreciated.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>Regards.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>----------------------------------------------------------------<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>Bolun Xu<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>University of Science and Technology of China<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>Department of Modern Mechanics<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>Hefei, Anhui, China<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p></div></body></html>
