Hi All,

I am a beginner so please if I made any stupid mistake, bear with me.

My objective is to simulate a 2D Wind Turbine rotor in fluent.
I have already done sliding mesh analysis of rotor for transient case.



This is the mesh file.

But for sliding mesh , omega and inlet wind speed both needs to be specified.

Therefore , I jumped on to 6 dof dynamic meshing so that I can simulate with inlet velocity only.

After reading udf manual this is how I am thinking of going ahead.

Torque= I*alpha,
w(t)= w(0) + alpha*(t).

w(0) is zero in my case.

Therefore
w(t)= (Torque/I)* (t),
ANd Torque = rXF, F= P*A;

P= F_P(f,t),
F_AREA(A,F,t) = Area vector of Face,

x[ND_ND]
F_CENTROID(x,f,t)
r= (x[1]^2 + x[2]^2)^0.5.

Now I need to write all this in coding language and run the simulation which is ofcourse a big task.

I am not asking you guys to give me the code , but at least if you could tell me that whether I am thinking in the right direction or not.

Do I need to use DEFINE_CG_MOTION ??? but the CG of the rotating domain is neither rotating or translating.
