Hello every one.
I've spent alot of time searching and looking for the noiseDict because when I tried to use the noise utility the program asked for this dictionary.
Based on the noise.c I built this noiseDict and I don't know if it the correct one
Code:
/*--------------------------------*- C++ -*----------------------------------*\
| =========                 |                                                 |
| \\      /  F ield         | OpenFOAM: The Open Source CFD Toolbox           |
|  \\    /   O peration     | Version:  2.3.0                                 |
|   \\  /    A nd           | Web:      www.OpenFOAM.org                      |
|    \\/     M anipulation  |                                                 |
\*---------------------------------------------------------------------------*/
FoamFile
{
    version     2.0;
    format      ascii;
    class       dictionary;
    location    "system";
    object      noiseDict;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

    pRef        101325;
    N           65536;
    nw          100;
    fl          25;
    fU          10000;
    graphFormat raw;

    csvFileData
    {
        fileName        "pressureData"
        nHeaderLine     1;
        refColumn       0;
        componentColumns (1);
        separator       " ";
    }


// ************************************************************************* //
But when I tried to execute the noise command in my terminal in a case folder of a simulation of flow around an obstacle (S-A DDES with a pressure data recorded py a probe) the following error message came out.

Code:
a-habib@a-habib:~/test/testCase$ noise

So any idea about that definition above ????

Hi,

The reason for the error is missing semicolon after "pressureData".

Hello, I try to CAA simulation flow around the cylinder. I finish my simulation and use the probe for measure velocity and pressure behind the cylinder. Now I try by my noiseDict compute SPL. How format do you set up in probeDict?

noise documentation is incorrect.
