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

Seequent Central

  • Cloud hosted on Microsoft Azure and requires an internet connection, with no offline or self-hosted option
  • Hosting instances start at a minimum 500GB of storage, with more sold as an add-on
  • Billing splits into three separate lines: cloud hosting per organisation, user subscriptions per person and Leapfrog Connector licences per modeller
  • Publishing models from Leapfrog into Central requires a separate Leapfrog Connector licence
  • Value depends on already owning other Seequent tools such as Leapfrog, GeoStudio, PLAXIS or Oasis montaj
