Hello everyone,

I am running a laminar simulation at Re=100 using pimpleDyMFOAM to get the starting vortex. In order to move the airfoil, I use the SolidBodyMotionFvMesh with the application 6DofMotion. I accelerate the airfoil from 0 to 1 m/s in 1 sec.

For some reason, I don't see to get the simulation right. Can somebody tell me where am I wrong?

here are the conditons

}

Please explain the problem or error properly which you get while running the simulation.
