DiverInterCom KCore Scuba — VPM-B Microbubble Planner V0.2 Experimental

Experimental validation build — VPM-B only. Classic Varying Permeability Model with critical-volume iteration and Boyle-law compensation. No Gradient Factors and no Bühlmann M-value ceiling are used to generate the schedule. This V0.2 build is for research/testing only and is not validated for operational dive planning. VPM-B conservatism and bubble-state diagnostics are exposed to support comparison against independent planners.

Bottom profile

Depth m Runtime to ascent min Bottom gas preset O₂ %He % Descent m/minAscent m/min Deco ascent m/min

Three optional decompression gases

Deco gas 1 O₂ %He %Switch m Deco gas 2 O₂ %He %Switch m Deco gas 3 O₂ %He %Switch m

All deco gases start OFF. Gas switches are explicit and occur only after reaching the configured switch depth.

Conservatism +0 preserves the V0.1 baseline. Levels +1…+4 scale both critical radii by 1.05 / 1.12 / 1.22 / 1.35 respectively, matching the public Subsurface VPM-B conservatism scaling approach. Base radii and λ remain visible for validation work; keep them at their defaults unless deliberately testing the model.

Dive profile

Engine note: This standalone test engine implements 16 N₂/He compartments, VPM critical nuclei, descent crushing pressure, nuclear regeneration, initial allowable gradients, decompression-zone search, critical-volume iteration, Boyle-law gradient compensation, and staged stop release. It is intentionally separate from the DiverInterCom ZHL-16C/GF planner.
