Hello
I did one simulation of incompressible flow over a pitching airfoil at Re=12000 using openFoam solver. For example, the velocity contour at one angle of attack is as attachment pic. As you can see, flow has a lot of stagnation point which may not seem correct physically. Is there aerodynamic justification for this streamline? In addition, the solution has been validated in terms of aerodynamic forces.
thanks.

can you tell which dynamicmeshdict you used for pitching

[arashfluid]

I use this dynamicMeshDict:

dynamicFvMesh dynamicMotionSolverFvMesh;

motionSolverLibs ("libfvMotionSolvers.so");

solver displacementLaplacian;

diffusivity inverseDistance (airfoil);

Hi Arash,

I must do the same project in OF As yours but i am stuck in really bad problem.
I generated my mesh in gambit like pic i attached. I dont know why the OF could not recognize the interface boundary.
My dynamic mesh dict is same as yours.
