Where each one falls short

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

Deswik Suite

  • Deswik publishes no price, no licence term and no cost driver for the suite; the only routes given are a demo request or contacting the company
  • The suite is sold as separate modules grouped under Design and Reserving, Planning, Operations and Mine to Market, so a full workflow requires buying several products
  • Software downloads and support are gated behind a client portal available to existing customers
  • The product formerly sold as Deswik.CAD is now named Deswik Spatial, so older documentation and job listings refer to a name the vendor no longer uses

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
