Hello, does anybody has a TDMA subroutine with periodic boundary conditions at I=1 and I=NI (or whatever other combination, 2,NI-1 , 2,NI etc.) that he can send me. Or suggest me a good site where I can download one. Iam writing a 3D code for unsteady compressible turbulent flow in cylindrical coordinates and I cannot continue,because I have this problem with my TDMA subroutine. Thank you in advance

hello again, the site which Enrico suggested is very profitable.does your problem exist as yet?

Hi;

which site,please tell me

refer to some items downward which named "patankars cyclic TDMA"

The code you require is listed in numerical recipes http://www.nr.com/
