hi everyone.

To simulating an oscillating airfoil i use this solver (displacementSBRStress) to dynamic mesh. and now i want that the airfoil oscilat between 0-15 degree. but when i setting up like below it oscillat between15 to -15 degree. can anyone knows what should i do? and how can i calculate the angle of atack in paraview?

thanks.
