Pre-existing fractures (DFN authoring)
Import or hand-pick a natural-fracture population that the non-planar 3D solver reads at simulation start. Supports CSV import with header aliases (x · y · strike · dip · radius · aperture), two quick presets, a plan-view preview, and an optional heterogeneity overlay that tints + scales each disc by the local Gaussian random-field multiplier (same knobs as /heterogeneity).
Pre-existing fractures (plan view)
0 fractures · mean R 0.0 ft · mean strike 0° · mean dip 0° · field K_IC (toughness) · L_corr 120 ft · seed 1
Heterogeneity overlay
Discs tint blue (low multiplier) → red (high) and scale ×0.25–×2 by the field sampled at their (x, y). Same Gaussian random-field engine as /heterogeneity.

Drop-in fracture populations for quick what-if scoping; both feed the same `nonPlanar3D` NF-branching path as imported sets.
