Error when reading data file.

WJXu · April 19, 2014, 16:24

hi, all.

When I am using fluent to read data file, a warning shows up as:

Skipping data sub-section 200 for thread 10022. Wrong size (6 != 1)
Skipping data sub-section 200 for thread 17. Wrong size (6 != 1)
Skipping data sub-section 200 for thread 20030. Wrong size (6 != 1)
Skipping data sub-section 200 for thread 20031. Wrong size (6 != 1)
Skipping data sub-section 200 for thread 18. Wrong size (6 != 1)
Skipping data sub-section 200 for thread 19. Wrong size (6 != 1)
Skipping data sub-section 200 for thread 20. Wrong size (6 != 1)

Warning: read_eqn_residual_section: Incorrect size (1 != 5)
Warning: read_eqn_residual_section: Incorrect size (1 != 5)
Warning: read_eqn_residual_section: Incorrect size (1 != 5)

Done.

does anyone have similar question? Any help and advice are highly appreciated.

I want to export the data file from fluent to tecplot with specified file extension, since I found that the file extension could be .dat / .plt based on different machine. Is there anyway I could set this myself?

You may be using a different case file and a different data file.
Such problem has occurred to be in such a case.

A Tecplot file with a .dat extension is in a Tecplot ASCII (or text) format, while a Tecplot file with a .plt extension is in a Tecplot binary format.
Of course, one can directly read Fluent’s default ouput (.cas & .dat files) with Tecplot’s Fluent data loader.

Thanks for your reply. But this is not the reason, I am sure I am reading the correct cas and dat files. When I read the same files on the supercomputer, everything is fine. When I read them on another machine, something described happened.

Forget to mention, I am simulating the reacting flow. So I first obtain a non-reactive flow, then add chemical reactions. Do you think this may lead to the problem???

i got the same problem, have you solved it? thanks

hi, have solved it? I have the same problem when ran my case on the cluster.

I believe the issue might be with the fact that the cluster maybe running a newer version of Fluent (>14.5) and your personal machine is running an older version.
