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 2.1.6.3. 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 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.

artin:
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?

Thanks
Musa

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

Hi,

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

Cheers,
Pierluigi

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.

Looks to me like you have to do more than pay attention to the format. A lot of functionality that in principle should be there, isn't. For example, I've found that in some places, you can put a hard-coded number, but not a variable. I'll limit myself to documenting problems that are stopping me in my tracks.. ..well.. quick example:

    {
        name    cs;
        type    cellSet;
        action  new;
        source  cylinderToCell;
        sourceInfo
        {
            point1 (0 0 -100);
            point2 (0 0  100);
            centre (0 0 0);
            radius $cylinderRadius;
        }
    }

Those numbers after point1 and point2 and center? those can't be variables. oh, and "innerRadius" following radius doesn't do anything. that might be a .org vrs .com issue though..

Hi,



I have solved a similar error by changing the fvSchemes file, default sheme from Gauss upwind to Gauss linear as below:



divSchemes
{
default Gauss linear;
div(phi,U) Gauss upwind;
div(phi,T) Gauss upwind;
div(phi,k) Gauss upwind;
div(phi,epsilon) Gauss upwind;
div((nuEff*dev(T(grad(U))))) Gauss linear;
}


I hope it helps to someone.

Hi, I met the same error.
The "default Gauss upwind;" does not work. However, "default Gauss upwind phi;" does work.
