Hi,

The solver runs properly for amplitude of 20 degrees. I tried for 30 degrees and its crashing.

I use moveDynamicMesh to see if the mesh quality is OK in all the time steps. Then I proceed to use the pimpleDyMFoam solver to calculate the flowfield.

Thanks,
Pruthvi.

If the mesh quality is fine using moveDyMesh. if should works with the fluid solver as well.
If you are using fixed time step try to used adjustable time step based on Co. number.

airfoil is not moving

it is my first time to use github, so it could be not working or I messed up something.

Hi hk318i (Hassan Kassem),

I am facing small issue while running your code, can you help me to resolve it?

I am performing pitching and heaving motion of airfoil. Your code compiled without any error. However, while running simulation I faced one error as " there is no new entries for fvMotionSolver", so I replaced libfvMotionsolver.so into libmy2DOF.so. After that, simulation ran but my boundary is not moving, it behaves like a static airfoil motion.
I don't know where I am doing wrong. Please correct me or guide me.

Thank you so much

Best Regards,
Ram
