I want to Sense RPM of a wind turbine blade after every time step and for this I have written a UDF as follows:

#include "udf.h"

DEFINE_EXECUTE_AT_END(rpm_sensing)
{
int zone_ID = 7;
Domain *domain;
domain = Get_Domain(1);
Dynamic_Thread *dt;


Thread *t = Lookup_Thread(domain,zone_ID);
face_t *f;
t = DT_THREAD(dt);


real omega;
real rpm;
omega = NV_MAG(DT_OMEGA_CG(dt));
rpm = (omega*60)/(2*3.14);
}

but whenever I compile it, it gives me a warning: warning C4700: uninitialized local variable 'dt' used.

My question is, how can I assign a Thread to be a Dynamic Thread? If that is not possible how should I go about sensing the angular velocity of the whole thread at every timestep?

can't answer your question, but a certain problem is that you did not assign dt.

you did:
Thread *t = Lookup_Thread(domain,zone_ID);

for a regular thread, but not for dt.
