Hi,
I would like to do something along the lines of probe as described in pitzdaily tutorial. However, I would like to save the data along a surface and not at certains coordinates.

I modified the controlDict as shown below and am getting an error

Quote:
ill defined primitiveEntry starting at keyword 'probeLocations' on line 64 and ending at line 85
The portion of controlDict is pasted here for your reference
Code:
functions
{
probes1
    {
        type            probes;
        functionObjectLibs ("libsampling.so");
        enabled         true;
        outputControl   timeStep;
        outputInterval  1;
        probeLocations
        (
            midplane
        {
        type plane;
        basePoint (0 -0.086 0.00046);
        normalVector(0 0 1);
        }
        );

        fields
        (
            p
        );
    }    

        
}
can anybody help me with fixing this problem

Regards,
Vishwa

After digging a little bit further, i found this link

SampledSurfacesFunctionObject

and changed the controlDict accordingly.. It now reads

Code:
functions
{
probes1
    {
    type            surfaces;
        functionObjectLibs ("libsampling.so");
        //enabled         true;
        outputControl   timeStep;
        outputInterval  1;
    surfaceFormat raw;
    interpolationScheme cellPointFace; 
    
        fields
        (
            U
        );     


    surfaces
        (
            midplane
        {
        type plane;
        basePoint (0 -0.086 0.00046);
        normalVector(0 0 1);
        }
        );
        
    }
Now i get this error

Any help?

playing further with the surfaces, I found in one of the tutorials which uses surfaces in the controlDict (sloshingtank2d3d0F), here they use a patch and not a plane. I changed it to patch in my controlDict file and the code starts to run. But, I would like to save the data on the midplane,which hasn't been defined in the boundary in the constant folder. I need this so that I can make a movie of the vector fields. I am pretty new to Openfoam and still learning the ropes.

Any suggestions please...

Best regards,
Vishwa

finally figured it out....

I had typed normalVector(0 0 1) ..there should have been a space between normalVector and paranthesis...normalVector (0 0 1)
