Hi everybody! Does anybody has the subroutine of the cyclic TDMA of Patankar?Can you send me it? Thank you in advance

Or any other subroutine concerning cyclic or periodic boundary conditions...

Hi, If it is TriaDiagonalMatrixAlgoritm, you can find it Numerical Recipies in FORTRAN or Numerical Recipies in C.

i have a TDMA subroutine. but what you mean by cyclic. if it is a slice from axisymetric 360 degrees. please explain it.

Yes, it is a TriaDiagonalMatrixAlgoritm.But if there are cyclic or periodic boundary conditions in the flow, then there is a different version.I am trying to change it, but I have some problems. For Ali Mottalea: It is not axisymmetric, it is full 3D cylindrical flow.

ok. then as i know your coordinate system is cylindrical and in teta=0 and 360 you have cyclic condition. is it true?

Yes. And you must change a little bit the original TDMA, so that you can take into consideration this difference in the usual boundary conditions

For symmetric tridiagonal matrices (diagonally dominant) you can give a look here:
