Vortex generator design vİth multi angle of attack
 

hi all - anyone may help me
Im wondering that
1. For parametirazing angle and other value of Vortex generator and airfoil angle (3D) which is Best spaceclaim or design modeller to design

2. I want to use ıcem cfd with this parameters to calculate multi resault (for eg. CL AND CDmax etc) . Is there any key to learn before start. In my Last 4-5 try I encounter problem which didnt start autonomous mesh (didnt create mesh) and only airfoil and enclousure is created on icem.
Do i have to click record button before start to do this autonomous steps and after all mesh done do i have to make unstructured mesh and save.

3. Last: vortexes generated by generators ıs not regular or Line Flow. So is unstructured mesh (with normal meshing program not icem) better for this study?
