Joel,
  I have forgotten what the problem was with the Godunov solver but I will
look at putting an intermediate version of Overture, v22n, on the web site.
This will likely take a few days.

Hi Bill,

I wonder if there is a patch ready for the godunov version of cns solver.  For 
the moment I'm using the jameson solver which runs fine, but I cannot use AMR.


Cheers,

Joel

Hi Joel,
  We have been running quite a few 3D cns cases. I know we
have fixed some issues with 3d parallel AMR. It must be
that there are some bugs in your version. Hopefully I will
be able to put out a new version sometime soon.

Regards,
Bill.

By the way,

I'm getting the same segmentation error for all cns 3d cases.  It is fully 
working the 3d version of the cns solver?

I get this error trying to run the shockTube3d.cmd testcase included in the cg
