bhat_nikhil is on a distinguished road
I want to use the UDF for specifying the rotation of 2 bodies. Please see figure attached(Rotation domain.pdf). As shown in the figure there are 2 bodies, nozzle 1 and nozzle 2. Nozzle 1 rotates about the global coordinate system whereas nozzle 2 rotates about axis 2. I managed to achieve the rotation of nozzle 1 around a circle(as shown in figure) by coinciding its axis of rotation with the global coordinate axis(since in the Define_CG_motion UDF, the axis of rotation by default is global Z axis). However I not able to achieve the rotation of nozzle 2 about axis 2 which is different from the global coordinate axis( as by default the UDF will assume that nozzle 2 rotates around global z axis).
So how do I specify the rotation of nozzle 2 around axis 2 in the UDF?

Thanks in advance
