Hi,

I am looking for a way to insert a string into a subdictionary during runtime. This is not an elegant solution and it's part of a workaround to OpenFOAM 2.2.x port of Mesquite. I am discussing the reasons for this workaround with the creator of the port over here:

https://github.com/smenon/dynamicTopoFvMesh/issues/4

I would like to place patch information into a subdictionary. The main problem is that the patches are not an IO object and they are read from dynamicMeshDict. For separate reasons I would like to keep it like this for now. I will describe the situation in steps:

Code:
Info << fvpDict << endl;
results in
Code:
{
    GEOM                                                                                                               
    {
        type sixDoFRigidBodyDisplacement;
        centreOfMass    ( 0.5 0.83 0 );                          
        momentOfInertia ( 1 1 0.01 );                                   
        mass       0.01;                                                                                             
        rhoName     rhoInf;                                                                                           
        rhoInf          1000;                                                                                             
        report          on;
        accelerationRelaxation 0.5;
        value           uniform ( 0 0 0 );
    }                                                                                                                     
}
being printed in the log file. Now I update the patch field by

Code:
pField().updateCoeffs();
Info << pField() << endl;
pField is an autoPtr so I need (). This recalculates 6DoF so the print out says:
Code:
type            sixDoFRigidBodyDisplacement;

Is there any way to substitute the former with the latter in fvpDict? I've tried a number of things involving set, add and clear and only clear worked for me. Basically I would like to clear GEOM entry during runtime and put a new one which corresponds to updated pField.

Please let me know if that's possible with current implementation of dictionary object.
