Hey friends,


Does any one know about how to use the custom rotation matrix and derivative rotation matrix in 6DOF module of fluent.


Basically I want to do the cfd analysis of wind turbine blade.the blade does not have 6DOF it has only one degree of freedom so I want to constrain the motion of blade in one axis rotation only.To constrain the motion of a free falling body we need to use transformation matrices.


I have tried it by using certain transformation matrices but the motion is not constrained as by the requirment.

Please if anyone can help me that what is the basic theme behind CTRANS and DTRANS.


I will be really thankful...
