How can I simulate a flapping motion which the phase difference between pitching and heaving is not zero by Fluent?

Hi I'm simulating a flapping airfoil(Naca0015) by AnsysFluent How can I simulate a flapping motion which the phase difference between pitching and heaving is not zero? I used this UDF for...

Why does the pitching airfoil simulated in Fluent using a UDF has unexpected amount of lift?

Hi I'm simulating an unsteady harmonic 2D motion(pitching) for an airfoil in Fluent using a UDF. The amplitude of pitching is 15deg,the angle of attack is 10deg. trying to validate with a...

Why do we define the derivation of the Alpha(t) as omega in DEFINE_CG_MOTION macro?

Hi there To simulate a pitching motion some guys have applied this UDF : DEFINE_CG_MOTION the main sentence for pitch modeling in this UDF is: omega[2] = -a*w*cos(w*time); /* z-component of...

Why the grid motion is not an oscillation?

I've simulated a pitching motion in Ansys Fluent with UDF, a CG_MOTION mocro.The domain is supposed to oscillate but it rotates,judging by animation. The motion is not a pitching...
