In OpenFOAM, the rotating motion by rotatingMotion.C is prescribed with a fixed angular velocity.
I want to create a library to rotate by wind force from the rotatingMotion.C.

A similar library is reported in
http://hichem-hajaiej.com/wp-content...014/10/421.pdf.
What I want to make is the above FDRotationMotion.


A portion of forceDriveMotion.C, created by copying rotatingMotion.C, is shown below.
When I compile it, an error occurs and I do not know how to solve it.


Thus, there is an error in the mesh definition and we cannot obtain the mesh data or the pressure at the object boundary.
Therefore, it is not possible to determine the torque required to rotate the object.

Please give me any advice.




Foam::septernion
Foam::solidBodyMotionFunctions::forceDriveMotion:: transformation() const
{
//
fvMesh& mymesh;
forAll(mymesh.cells(), cell_id)
{
Info << "cell_id = " << cell_id << endl;
}
