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

Surpac

  • 3ds.com's Surpac page describes nine product modules in detail but every pricing action is a 'Speak with an expert' or 'Contact us' CTA, with no edition names or figures published
