Hi,

I am currently trying to move some boundary points (in normal direction) with OpenFoam 1.6. Therefore I am playing around with the dynamicFvMesh stuff. This is all working great. I have created a 'dynamicMeshDict' containing:
dynamicFvMesh dynamicMotionSolverFvMesh;
solver displacementLaplacian;

I have also create a 'pointDisplacement' file and modified it sth some points are moved. This also works as expected and paraView shows the result as expected.

In the next step I tried to modify the pointDisplacement field from within my solver/application.
I get a reference by using
pointVectorField &pointDisp = const_cast<pointVectorField&>( mesh.lookupObject<pointVectorField>("pointDisplacement") );

This should be ok, but as soon as I try to access the field eg by writing
Info << pointDisp;
I can't compile anymore. wmake aborts saying

[...]

Can anyone please help me with that?

Best regards,

ok, I have just managed to modify the boundaryField of pointDisplacement.

PHP Code:

#include "fixedValuePointPatchField.H"
// ...

int main ( ... )
// ...

pointVectorField &pointDisp = const_cast<pointVectorField&>( mesh.lookupObject<pointVectorField>("pointDisplacement") );

fixedValuePointPatchField<vector> &boundaryPatch = dynamic_cast<fixedValuePointPatchField<vector> &> (pointDisp.boundaryField()[patchID] );

// values can be changed eg by writing
boundaryPatch[0][1] = 6;

Nick,

would you mind sharing your #include list? I'm always getting

error: no match for ‘operator[]’ in ‘boundaryPatch[0]

Thanks,
Arne
