Hello everybody. Just regis
Hello everybody.

Just registered for an account and am going through the tutorial in order to learn OpenFOAM and something about numerical fluid simulation. I hope you can help me with this problem:

At this moment I came to page 39, chapter Foam is version 1.1 running on Suse linux 9.2.

I type in the command: "mapFields . cavityFine
/ . cavityGrade/ -consistent", but why do I then get the following error message?

Hi there, Just for the arch
Hi there,

Just for the archive: I don't know what was wrong but overwriting the tutorials directory including subdirectories with the original files solved the problem.

Strange error message, IMO.

Best regards,

artin: I have the same issue
I have the same issue with parafoam as you did. When I try to view the cavity case mesh with parafoam in accordance with the openfoam tutorial documentation, I get the eof error. However, unlike your case, I am not being able to solve it by reloading the tutorial files. Any suggestions?

I have the exact same problem.

This problem seems to arise when you use an older version input method in files for a newer version of OpenFOAM. Check that the way your data is written (or copy pasted from say a website) is consistent with your installed version file format (written like the examples)

i think wrong definition uniform or nonuniform scalar. it needs to add scalar value after

Try to check the format. Sometime I have this error when I forget " ; ".

same problem
I had the same problem. I forgot the blank space in the dict file. So if you have the same problem, just pay attention to the format.:)
