[Nek5000-users] Nek5000-users Digest, Vol 88, Issue 4, Problem creating .rea file

Mon Jun 6 14:58:31 CDT 2016

Hello all,

Thanks jing, that was a lot helpful to me.

I have generated the .msh file for the hexahedral mesh for my geometry. File is attached to this mail.

I have given boundary condition in this file only let me know if there are any changes to be made and file has only one zone( if by one zone you mean only 1 type of mesh through out whole geometry).

Questions:

1) Users, what are other ways to convert (Icem cfd) .msh  file to .rea file?

2) is there any way to smooth hexahedral mesh for unstructured geometry?

Thanks,

Mansi Patel

Hi Mansi,

1)what should I do to solve error?

Right now mshconvert can only deal with single zone's case. So you should have to manually merge the multi-zone to single-zone in the .msh file.

Also we found that there are few bugs in the file.  Could you please send us your .msh file to test  and then we will get back to you with the corrected version?

2)what are mesh types that we can use?
Quadrant  for 2D- and hexahedral for 3D-cases.

3) I there any other easy way to convert .msh file to .rea?
I leave this question to other users.

Thanks.

Regards, Jing

Hello all,

I want to ask what type of mesh does Nek5000 accept? tetrahedral, hexahedral,etc?

Because I am using ICEM CFD for generating mesh which has extension .msh and for that I used python code given for mshconvert to convert into .rea file but I am getting error. the error image is attached.

Please let me know following questions

1)what should I do to solve error?

2)what are mesh types that we can use?

3) I there any other easy way to convert .msh file to .rea?

Thanks, any help would be appreciated.

Thanks,

Mansi Patel
