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.

What people use each for

The jobs each tool is most often brought in to do.

GeoStudio

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
