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
