3DEC - Details and Requirements

3DEC is a numerical modeling code for advanced geotechnical analysis of soil, rock, and structural support in three dimensions. 3DEC simulates the response of discontinuous media (such as jointed rock) that is subject to either static or dynamic loading.

3DEC Facts

3DEC has been available for more than 18 years and is used by engineers, consultants, and researchers in more than 30 countries around the world.

3DEC is an accurate and efficient geotechnical analysis tool, using an explicit solution scheme that gives stable solutions to unstable processes. 3DEC can model mine-scale operations and large structural complexes.

Because Itasca is both an engineering consulting firm and a software developer,3DEC is developed in a practical environment driven by considerations derived from real-world problems. We know what those problems are, because we tackle them every day.


Minimum Requirements

  • Platforms: Windows Vista, Windows 7, Windows 8 and Windows 10 (Please read our full OS Policy)
  • Hard Drive: 200 MB
  • Memory (RAM): 100 MB
  • Video: Graphics card with OpenGL 1.3 or higher
  • Processor: 2GHz or better (Increases to the RAM or the processor speed will result in improved performance.)

Note: These are minimums required to install and execute 3DEC. Actual Requirements will vary depending on the model that is created. Models can be created on a 64-bit system that can be many Gigabytes in size and require a similar amount of hard drive space to store. A more realistic system would have 4-8 Gigabytes of RAM and 1-2 Terabytes of hard drive space.
