The short version

  • Each has a real cost: GeoStudio the GeoStudio product page publishes no price and offers only a contact sales route or a link out to the Virtuosity reseller; UDEC the UDEC product page publishes no price and directs buyers to a quote request or an external software store
  • They diverge on capability: GeoStudio covers Slope stability analysis, UDEC covers Distinct element 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.

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

UDEC

  • The UDEC product page publishes no price and directs buyers to a quote request or an external software store
  • Fluid Flow, Barton-Bandis joint analysis, Creep, Thermal and User Defined Models are optional add ons charged on top of the base licence
  • Writing custom constitutive models requires the separately licensed UDM option and C++ programming
  • Purchases through the Buy Now route are prepaid annual subscriptions rather than a permanent licence
