Hi everyone,

Do you have any UDF for dragonfly motion including stroke plane deviation. I am trying to simulate the dragonfly motion as given by Z JANE WANG. But I am not yet succeeded. It seems to be very difficult for me as I am new to UDF concept.

In that he has used 2-D cross sectional Wing executing the following motion

Center of chord is given by
x(t) = A0/2 * (1+cos(2*pi*f*t))*cos beta
y(t) = A0/2 * (1+cos(2*pi*f*t))*sin beta

Here A0 (amplitude of translation) = 2.5 ; f(frequency)=1 ; beta(stroke plane inclination) = 60 degree

alpha(t)=alpha(0)+B*sin(2*pi*f*t + phi)

B (amplitude of rotation) = pi/4 ; alpha(0)= pi/2; f=1; phi(phase delay between translation and rotation = 0.

Kindly help me with this UDF
