Hi, everyone,
I want to simulate a airfoil making pitching osicilation.  =10+5*sin( *t). The airfoil rotates as the equation shown.I want to write a UDF file to describe the motion and at the same time using 6DOF to simulation its motion in vertical direction. Now I have used DEFINE_CG_MOTION(describe the oscilation motion) and DIFINE_SDOF_PROPERTIES(freeze the vertical direction) to describe the airfoil. However, I found FLUENT can not use two micro for airfoil motion at the same time. How can I solve the problem? Best wishes. |
