Dear Cactus users,

It is introduced in the UsersGuide of Cactus that the grid arrays can only be determined by function calls, rather than the quicker methods available for GFs. But is there a better way to deal with the grid arrays so far?

I am trying to analyze some physical quantities in equatorial plane, and get the grid function in spherical coordinates by interpolation. It doesn't seem so convenient, if I define this new variable as grid arrays,

Thank you

best regards
