Hi,

I tried to modify the wingMotion2D tutorial, changing from sixDoFRigidBodyMotion to solidBodyMotionFunction because I want to simulate a pitching airfoil:

dynamicFvMesh      dynamicMotionSolverFvMesh;

motionSolverLibs ("libfvMotionSolvers.so");

motionSolver solidBody;

cellZone        wing;

solidBodyMotionFunction  rotatingMotion;
  
rotatingMotionCoeffs
	{
	origin (0.25 0.007 0.125);
	axis (0 0 1);
	omega 6.2832;
	}

However, I got the error:

Unable to find cellZone wing. Valid cellZones are:0()

Why is this so? I searched and it seems that I need to create a set file using setSet or topoSet? But how is it done? Can someone enlighten me?

Thanks.
