We are always aiming to expand the capabilities of our software and RS2 is no exception, having had 11 new versions since its inception and over 150 updates since 2008 alone, to make it a leader among finite element analysis software. Since then, it has taken shape into a powerful finite element analysis program for both rock and soil. As its features became more effective at analyzing soil mechanics, the name was changed to RS2 (RS standing for Rock and Soil) with the release of version 9 in 2015. Version 6 introduced Static Finite Element Groundwater Analysis followed by advancements in Transient Groundwater Analysis in Versions 7 and 8.

In 1999, the first Windows based program was released, and the program was renamed Phase2. When RS2 was first in development in the early 1990’s, it was a DOS program known as PHASES which focused primarily on rock mechanics and mining applications. To truly appreciate the capabilities of the modern geotechnical software we use today, we must look back at their origins.
