anybody know how to plot roll or pitch motion in cfd post

Hello, I'm trying to observate the roll or pitch motion of a offshore plant model. I've tried to simulate using a setup(with 6DOF which is Ixx=Iyy=Izz=0.351, initially set rotate 25 dgree) but I'cant found a way to plot the degree x time grafic in cfd post for the decay.

thank you for your attention!

Hi, You can use a UDF to observe angles (you can find it in the UDF manual).

Message(" = %f, %f, %f\n",DT_THETA(dt)[0], DT_THETA(dt)[1], DT_THETA(dt)[2]);
