i know there's a million threads about this topic but i browsed thru them and couldn't get any help.
i'd like to export numerical data of the field above and use it in matlab. I know i need to use the field calculator but i'm not sure how to create the grid points. If i select calculate grid points and give the coordinates, it won't accept same value for zmin and zmax, so basically it want's coordinates of a volume and not a surface.
Also is it possible to get the phi and theta components instead of x,y,z?
The surface is 16x16mm and centered in the point [0,0,10]
thank you in advance
