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 Geological Modelling user interface is dated compared to modern mining software
  • They diverge on capability: UDEC covers Distinct element modeling, Vulcan Geological Modelling covers Implicit 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.

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 Geological Modelling

  • User interface is dated compared to modern mining software
  • Requires extensive training and certification to use effectively due to software complexity
  • High-performance hardware requirements increase capital expenditure for infrastructure
  • Solids operations take an extremely long time to compute, limiting responsiveness
  • Premium pricing makes the software unaffordable for small and mid-sized mining companies

Vulcan Geological Modelling: What mining tasks can Vulcan perform?

Vulcan handles geological modeling, drillhole data management, block modeling, resource estimation, pit optimization, mine design, grade control, geotechnical analysis, scheduling, geostatistics, and rehabilitation planning.

Source
Vulcan Geological Modelling: What training does Maptek provide for Vulcan?

Maptek provides comprehensive training programs, documentation, and workshops for Vulcan users. However, the tutorials and workshops are limited and cover only basic functionalities, making advanced use of the software difficult without extensive hands-on experience.

Source
Vulcan Geological Modelling: What are the system requirements for Vulcan?

Vulcan requires a high-performance computer system with significant processing power and RAM to run effectively, which may necessitate additional hardware investment for smaller operations.

Source
Vulcan Geological Modelling: Is Vulcan difficult to learn?

Yes. Vulcan has complex components requiring extensive training to use effectively. Tutorials and workshops are limited and cover only basic functionalities, making the learning curve steep for new users.
