Add points using spherical coordinates.

createpts/rtp/2,6,30/0,0,0/1,,360/1,1,1
Argument Description
rtp specifies sperical coordinates
2,6,30 create 2 points in the r direction, create 6 points in the t direction, create 30 points in the z direction
0,0,0 rmin = 0, tmin = 0, zmin = 0
1,,360 radius from 0 to 1, angle in the xy-plane is degrees, angle in the zy-plane is 360 degrees
1,0,1 rmins and rmaxs are used as cell vertices, tmins and tmaxs are used as cell vertices, zmins and zmaxs are used as cell vertices
