The value of drag coffecient changes with the size of the enclosure I choose. I found values of -1.5, 1.14, 0.7. I do not understand the problem properly. Previously with other meshes the problem used to be solved when I used correct values for projected area. But for thsi mesh nothin is working. Can someone help me with a guidline.
