hello everyone

when i used pisoFoam to solve a problem about simulating 1/4 of underwater glider body with k-omega model, i encountered an error from openfoam. the full information is given:

I have searched many topics from the forum, and there are almost no similar problems. I have nothing to do with it.

However, when I cancelled part of functions from controlDict, I did not encounter this problem.

the controlDict:

application     simpleFoam;


startFrom       latestTime;

startTime       1;

stopAt          endTime;

endTime         10000;

deltaT          1;

writeControl    timeStep;

writeInterval   200;

purgeWrite      0;

writeFormat     ascii;

writePrecision  6;

writeCompression uncompressed;

timeFormat      general;

timePrecision   6;

runTimeModifiable no;

adjustTimeStep  no;



functions
{

    forceCoeffs1
    {
        type forceCoeffs;
        libs ("libforces.so");
        
        writeControl timeStep;
        writeInterval 1;
        
        patches (wall);
        
        rho rhoInf;

        liftDir (0 1 0);
        pitchAxis (0 0 1);
        magUInf 1.0;
        lRef 1.0;
        Aref 0.465;
        origin (0 0 0); 
        coordinateRotation
        {
            type EulerRotation; 
            degrees true;
            rotation (0 0 0);
        }
        
}

could anyone help me ?

thanks.

hi guys:

i simulated my case with openfoam-2.4.0, and it had no wrong information. it shill worked well even i added the forceCoeffs function in controlDict file.

why happened this between different version of openfoam?

[random_ran]

The force function do the bad thing, maybe try the following lines to your control file:

```
libs ("libOpenFOAM.so" "libfieldFunctionObjects.so");
```
