The short version

  • Each has a real cost: Deswik Suite deswik publishes no price, no licence term and no cost driver for the suite; the only routes given are a demo request or contacting the company; FLAC3D the FLAC3D product page publishes no price and routes buyers to a quote request or an external software store
  • They diverge on capability: Deswik Suite covers 3D mine design, FLAC3D covers 3D finite difference 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.

Deswik Suite

  • Deswik publishes no price, no licence term and no cost driver for the suite; the only routes given are a demo request or contacting the company
  • The suite is sold as separate modules grouped under Design and Reserving, Planning, Operations and Mine to Market, so a full workflow requires buying several products
  • Software downloads and support are gated behind a client portal available to existing customers
  • The product formerly sold as Deswik.CAD is now named Deswik Spatial, so older documentation and job listings refer to a name the vendor no longer uses

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
