Where each one falls short

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

FLAC3D

  • The FLAC3D product page publishes no price and routes buyers to a quote request or an external software store
  • Advanced capabilities including Dynamics, Thermal, Creep and IMASS are optional modules sold separately from the base licence
  • Licence portability depends on a physical USB key or a web licence managed centrally, rather than a simple sign in
  • One licence permits only two simultaneous instances on the same computer

GEOVIA GEMS

  • No pricing published on vendor website; requires contact with sales team
