Where each one falls short

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

RPMGlobal XPAC

  • RPMGlobal publishes no price, no licence model and no purchase route for XPAC; the software pages carry no cost information at all
  • XPAC is one of roughly 40 separate RPMGlobal products, so scheduling, simulation and asset management are separate purchases
  • Obtaining any pricing requires contacting the vendor through a contact or support form

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
