Boundary conditions for inclined incidence
I have a design of a periodic array of cylinders. I am using:
1- inclined injection not perpendicular injection (angle theta =16.7 instead of 0)
2- 90 polarized incident wave instead of 0 polarized wave, please check photo 1 to see my settings
I have a question regarding the boundary conditions I should use. I believe that I should use symmetric for x-min & x-max and anti-symmetric for y-min & y-max, is it right please? Or should I use periodic boundary condition for both x and y directions? Please let me know the correct one and why, thanks. Also, do I need to change any other settings away from the boundary condition to consider the inclined injection and 90 polarized wave?
