Hi.
I am unsteady simulation of an airfoil with a flap having pitching motions. Instead of the default sinusoidal motion, I defined the motion in the corresponding module in the file of 'grid_movement_structure.cpp' as dpsi = -Ampl[2]*(abs(sin(Omega[2]*time_new + Phase[2])) - abs(sin(Omega[2]*time_old + Phase[2]))); After I got the results, I viewed the animation of the simulation. The mesh deformation history was correct, but the lift coefficient history is a little bit strange. I wonder after I modified the 'grid_movement_structure.cpp', is there anywhere that I also should modify too. Many thanks Kevin |
