The short version

  • Each has a real cost: 3DEC pricing is not published; licences are quoted, with subscription and perpetual options; 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: 3DEC covers 3D distinct element analysis, 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.

3DEC

  • Pricing is not published; licences are quoted, with subscription and perpetual options
  • A specialist geomechanical tool rather than general purpose simulation, so it assumes the user is a rock mechanics engineer

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
