The short version

  • Each has a real cost: FLAC3D the FLAC3D product page publishes no price and routes buyers to a quote request or an external software store; Vulcan Geological Modelling user interface is dated compared to modern mining software
  • They diverge on capability: FLAC3D covers 3D finite difference modeling, Vulcan Geological Modelling covers Implicit modeling.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

FLAC3D

  • The FLAC3D product page publishes no price and routes buyers to a quote request or an external software store
  • Advanced capabilities including Dynamics, Thermal, Creep and IMASS are optional modules sold separately from the base licence
  • Licence portability depends on a physical USB key or a web licence managed centrally, rather than a simple sign in
  • One licence permits only two simultaneous instances on the same computer

Vulcan Geological Modelling

  • User interface is dated compared to modern mining software
  • Requires extensive training and certification to use effectively due to software complexity
  • High-performance hardware requirements increase capital expenditure for infrastructure
  • Solids operations take an extremely long time to compute, limiting responsiveness
  • Premium pricing makes the software unaffordable for small and mid-sized mining companies
