Hello!! I have to simulate a periodic rotation of an airfoil around the z-axis ( my problem is 2d) and calculate the instationary coefficient. The rotation is defined by a torsional time dipendent law:
alpha(t)= alpha0 + alpha^(jwt) How can I do to define a UDF that simulate the rotating wall?? I have tried to use an UDF but with no good results.... Hoping that someone could help me...is for my thesis!!! Thank you in advance |

You can refer to a UDF manual, such as you can define a DEFINE_REGID_MOTION, etc. The UDF program in that manual is very helpful.

I can't find a function called define_rigid_motion..I know about a function called DEFINE_CG_MOTION..someone can help me with this one?? Thank you
