Hi all,

I am trying to run SU2 with a CGNS grid. I am getting the following error, although the CGNS grid has coordinates in double precision:

CGNS coordinates are not su2double precision.

Does anyone know the reason for this and how to correct it?

I have compiled release 4.1.1 with the following features:
- parallel support
- CGNS support
- AD with --enable-autodiff --enable-direct-diff

I do not get any error with SU2 gird, but I do get one with a CGNS grid.

Any direction or hint will be useful.

Thanks,
Mandar

Which version of cgns lib you compiled? I use 3.2.1 and I had no problem in loading grids.

[kmandar]

I am using CGNS version 3.3.0 (the current stable version).

Since I did not have a fortran 2003 compliant compiler, I compiled it with the option --without-fortran. However, I did not have any compile or build issues for CGNS. Also some of my other CGNS grids work just fine.

Hey,
I am also facing the same problem while loading my CGNS mesh file.
what can be done further

Hey guys,

first of all the error message is of course not correct. it should be "double" instead of "su2double", search and replace error Anyway, like already mentioned, could you try to use version 3.2.1 of the cgns library ?

hey,
the error is same when tried with version 3.2.1 of the cgns library.

Hi,

can you link the grid and configuration file? Which grid generator was used?
