[petsc-users] Book for the PETSc finite volume method

[Rongliang Chen]

Hi Jed,

I am solving the 3D compressible Navier-Stokes equations. I have read 
the ex11.c for several days and still do not fully understand this. I 
will look at the older version as you suggested. Maybe I need to go to 
your office to ask you some questions. :-)

Best regards,
Rongliang
