FLAC3D
3D finite difference software for geotechnical engineering
As of 30 August 2026, FLAC3D's pricing is not published; the vendor quotes on request. FLAC3D is advanced 3D finite difference software used in mining for slope stability analysis, underground excavation design, and geomechanical modeling. Softwr lists it under Mining. FLAC3D is made by Itasca Consulting Group, launched in 1981, available on Windows, Linux.
Overview
What FLAC3D does
FLAC3D is advanced 3D finite difference software used in mining for slope stability analysis, underground excavation design, and geomechanical modeling. It enables engineers to model complex mining geometries and assess stability in three dimensions.
What people use it for
- Three dimensional continuum modelling of soil and rock behaviour
- Analysing underground excavation and mine stability including caving
- Coupled thermal, dynamic and creep analysis of geotechnical structures
The honest half
Where it falls short
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about 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
Cross-shopped
What people choose instead of FLAC3D
Each pairing was judged by two reviewers asking whether a buyer would genuinely weigh the two against each other. The ones that failed were deleted rather than published.

Softwr does not host reviews and shows no star rating for FLAC3D, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it. Tell us if any of it is wrong.
