: It was traditionally offered as a free program to provide reliable rock mass property estimates. or you need updated equations
Roclab 1.0 uses the 2002 edition of the Hoek-Brown criterion (without the 2018 updates for mi/GSI relationships). For research, note this discrepancy.
If you find the and setup too cumbersome, or you need updated equations, consider:
Unlike more complex finite element modeling tools, RocLab focuses on a specific, essential task: calculating and visualizing the strength parameters of intact rock and jointed rock masses.
