The short version

  • Each has a real cost: UDEC the UDEC product page publishes no price and directs buyers to a quote request or an external software store; Vulcan neither the Vulcan product page nor the Maptek store page shows a price, a licence term or a subscription length
  • They diverge on capability: UDEC covers Distinct element modeling, Vulcan covers Geological modeling.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

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

Vulcan

  • Neither the Vulcan product page nor the Maptek store page shows a price, a licence term or a subscription length
  • Vulcan is a base product extended by nine paid add on modules covering geology and estimation, open pit design, underground design, scheduling, grade control and geotechnics, so the entry licence does not cover a full workflow
  • Buying requires going through the Maptek store or contacting Maptek directly for a quote

Questions people ask

Is UDEC or Vulcan better?
Neither clearly leads. UDEC starts at On request and Vulcan at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, UDEC or Vulcan?
UDEC starts at On request and Vulcan at On request.
Does UDEC or Vulcan run on more platforms?
UDEC runs on Windows, Linux. Vulcan runs on Windows.
What is UDEC best used for?
UDEC is most often used for two dimensional distinct element modelling of jointed and fractured rock, assessing stability of blocky rock slopes and underground excavations, simulating fluid flow through rock fractures in mining and tunnelling. Of those, two dimensional distinct element modelling of jointed and fractured rock and assessing stability of blocky rock slopes and underground excavations are not what Vulcan is typically brought in for.
What can UDEC do that Vulcan cannot?
UDEC covers Distinct element modeling, Joint network modeling, Block interaction analysis, Support interaction. Vulcan covers Geological modeling, Block modeling, Mine design, Resource estimation. Both handle Leapfrog, Windows support.
