Hi all,

while trying to move a mesh by modifying the pointDisplacement file out of my solver, I got stuck. I could really need some help using and understanding refCast.

Here is what I got:

    pointVectorField& PointDisplacement = refCast<pointVectorField&>
    (
        mesh.objectRegistry::lookupObject<pointVectorField>
        (
        "pointDisplacement"
        )
    );
    
     vectorField& pDisp = PointDisplacement.internalField();
    vectorField& pDispOld = pDisp;
    
     pDisp == vector (0,0,0.001)+pDispOld;

The corresponding compilation error:

Hey,
I'm getting the same error. Did you manage to figure it out?

Best,
