Hi all,
I want to convert U absolute to U relative in cylindrical coordinate system. For example.My cell locate in (1 2 3).and the velocity vector is (2 3 4). So in cylindrical coordinate system this cell locate in(a b c). a=square(1^2+2^2)=2.236 b=arctan(2/1)=63.4 c=3 So I can get the cell's location is (2.236 63.4 3) But can I get velocity in cylindrical coordinate system? Ua=square(2^2+3^2)=3.605 Ub=arctan(3/2)=56.3 Uc=3? Thanks in advance. Last edited by sharonyue; May 16, 2013 at 05:08. |
