This line assumes the definition of ndims, which is not necessarily defined at such a point. This came about because I tried approximating a function that has different bounds on the input space for each dimension, but want to use Doubling for all the dimensions.
Minimum reproducible example:
using SparseGridsKit, LinearAlgebra
function borehole_fcn(x)
r_w, r, T_u, H_u, T_l, H_l, L, K_w = x
logrrw = log(r/r_w)
denom = logrrw*(1.5+ (2L*T_u)/(logrrw*r_w*r_w*K_w) + T_u/T_l)
num = 2pi*T_u*(H_u - H_l)
num/denom
end
borehole_bounds = NTuple{2,Float64}[
(0.05, 0.15), (100, 50_000), (63_070, 115_600), (990, 1_110),
(63.1, 116), (700, 820), (1_120, 1_680), (9_855, 12_045)
]
n = length(borehole_bounds)
knots = [CCPoints([b...]) for b in borehole_bounds]
(asg, f_on_asg) = adaptive_sparsegrid(borehole_fcn, n; knots)Error:
ERROR: UndefVarError: `ndims` not defined in local scope
Suggestion: check for an assignment to a local variable that shadows a global of the same name.
Hint: a global variable of this name also exists in Base.
