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; GeoStudio the GeoStudio product page publishes no price and offers only a contact sales route or a link out to the Virtuosity reseller
  • They diverge on capability: FLAC3D covers 3D finite difference modeling, GeoStudio covers Slope stability analysis.
  • 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

GeoStudio

  • The GeoStudio product page publishes no price and offers only a contact sales route or a link out to the Virtuosity reseller
  • Capability is split across separately purchased plans: three product plans for GeoStudio 2D, two for GeoStudio 3D, and GeoStudio Flow sold apart from both
  • Three dimensional analysis requires a different product plan from the 2D one
