Stress Map


Software Tools Developed by the WSM Team

We developed a number of tools that allow to analyse stress data, print user-defined stress maps and to facilitate the generation, calibration and visualization of 4D geomechanical-numerical models based on the Finite Element method. Head of the developer team is Moritz O. Ziegler and you can contact him if you have questions or visit his GiHub repository. In the following list you find a very brief description of the tools and the links for the software and manuals with detailed descriptions.

  • CASMO - Create A Stress Map Online: The complete new version programmed by Tim Hake is now based on GMT 6.1 in combination with Python. We are currently working on a standalone version of CASMO that will run under Linux, Windows and Mac systems. The publication will be this summer and announced in the WSM Newsletter.
  • stress2grid: The Matlab script estimates mean SHmax orientations on a regular grid using the statistics of bi-polar data. Two different procedures are offered and explained with examples in the manual. Both use a weights based on the data distance to the grid point and data quality. Check the manual for details.
  • GeoStress:This is an Add-on of the professional visualization software Tecplot 360 EX. It estiamtes from the 3D stress tensor resulting from numerical models that use the Finite Element method a wide range of scalars and vectors used in geosciences. Check the manual for details.
  • FAST Calibration:This Matlab script facilitates and speeds up this calibration process of 3D geomechanical-numerical modells that use displacement boundary conditions. It also supports the multi-stage modelling approach as explained in Ziegler et al. (2016). Check the manual for details.
  • Apple PY:The Python script Apple PY (Automatic Portioning Preventing Lengthy manual Element assignment for PYthon) automizes the process of assigning rock properties to a finite element mesh based on a given static 3D geological model. Check the manual for details.
  • HIPSTER: The Python script HIPSTER (Homogeneous to Inhomogeneous rock Properties for Stress TEnsor Research) provides an algorithm to include inhomogeneities in geomechanical-numerical models that use the solver Abaqus® or the GOLEM/MOOSE Framework (Cacace and Jacquey 2017). Check the manual for details.
