While trying to implement a low-storage solver I want to reuse variables. How does one turn off the dimensional checking in OpenFoam?

[henry]

You can switch off the checking at run-time by setting

dimensionSet 0;

in OpenFOAM-1.1/.OpenFOAM-1.1/controlDict.

[mattijs]

Or maybe you can reset the dimensions() on the volXXXFields to the correct type. (see GeometricField.H, dimensions() gives non-const access)

I also tried to switch off the dimension checking, but the folder .OpenFOAM-1.1 does not exist at the location OpenFOAM-1.1. Am I searching at the wrong position? (ps: I recognized that it is a hidden folder)

Thanks

If you are indeed still using OpenFOAM-1.1 (note the original posting was from 2005), the location should be the same.

If you are using OpenFOAM-1.5 (or later), you should use the ~/.OpenFOAM/ or ~/.OpenFOAM/1.5/ directories. The later is generally better for controlDict, since it might change in incompatible ways between versions.

Note that with OpenFOAM-1.6, you can also use the command

$ foamEtcFile -list

to list the various directory locations that will be examined for the "~OpenFOAM/" string expansion (the same logic that is used to locate the controlDict).

And the command

$ foamEtcFile controlDict

to determine which file OpenFOAM will find for your controlDict.

See "foamEtcFile -help" for more information.

Dear everybody,

If OpenFOAM is installed at opt directory, is it not possible to edit the file controlDict due to permission problems. Is there other way to change permissions?

[hajott]

You can copy the controlDict from /opt/openfoam230/etc/ to $HOME/.OpenFOAM/2.3.0/, which will override the settings in /opt.

Dear hajott,
I have copied the controlDict according to your suggestion.
But there is still a problem as in the attchment.
Could you help to check?
Thank you in advance.
