sampleDict keyword patchName not accepted
 

Dear all:
In sampleDict, I would like to know the pressure on the left wall. I am running a rectangular tank in sloshingTank2D. BlockMesh runs fine:

Now my sampleDict file has the following bits of code:

FoamFile

location "system";
object sampleDict;
}

end ( 0 -15.0 -5.0);

}
middle
{
type uniform;

start ( 0 0 5.0);
end ( 0 0 -5.0);
nPoints 10;
}
right
{

start ( 0 15 5.0);
end ( 0 15 -5.0);

}
);
fields (alpha1);
surfaces
(
wallPressure
{
type patch;
patchName leftWall;
interpolate true;
triangulate false;
}
);
fields (p);

I am trying to obtain the pressure at the left wall. patchName is per the users manual. However, when I try to run the sampleDict file, I get the following error:

FOAM exiting

For some reason, OpenFOAM is not recognizing the word patch or patchName though both are valid keywords. So the post processing fails. However, if I change patchName to patches and enclose leftWall in parenthesis such as (leftWall), then sample processes fine. So has the keyword patchName been deprecated in OpenFOAM or is it not being used in the correct context? BTY I am running OpenFOAM build 2.0.1-51f1de99a4bc on Ubuntu 11.10.

Any help / guidance on this issue would be greatly appreciated. Thanks!!!

This is due to the different versions of OF.
In new version, the format is like this ?

type patch:
patches ("xxxxx"):

Hi, Cong.

yes, the keywords for surface with the type of patch in new version has been changed. But I think it is shown as below which is little different from that you written.

type patch;
patches (xxxxx); //the name of patch

Hi Mr Zhou,

Thank you for your reply. I have fixed the problem and moved on.

By the way, I saw your address is Shanghai. Could I ask which company are you working with? Is OpenFOAM popular in China?

I am a Ph. D. candidate and has not a job. I think OpenFoam is popular in China nowadays.

哦。 是上海交通大学吗？

No, Tongji University
