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 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 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
 

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.
 

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,

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.:)

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:



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.
