UDF help! C_centroid
hi,
i have a 2D circular disc of certain radius. how do i find the radius of each point(cell) in my domain. if i use c_centroid, i guess i will get the cordinate of the centroid of each cell,in cartesian coordinates. i couldnt find an example to extract the x and y coordinates using arrays. how do i reterive the centroid of each cell in cylindrical coordinates. i would be greatful, if anyone could help me get the radius of each cell from the center of the disc. an example would be greatly appreciated. thank you. bikash |
