GeoCalc (was OSXGeoCalc) is a calculator for vectors (lines, planes, and oriented drillcore data), and tensors (strain and stress). Vectors operations can be visualised in a Stereonet, and tensor operations in a Mohr Circle. Besides being a great tool to learn vectors and tensors operations, GeoCalc is a powerful tool to perform batch operations on thousands of vectors or tensors stored in text files.

GeoCalc was made for geologists, but it can be used by anyone interested in vectors and tensors (engineers, physicists, mathematicians, etc.).

What's New

Version 5.2:
  • In 3D stress, a new View -> Slip Tendency menu color Stereonet and Mohr circle by slip tendency (see third screenshot)


  • OS X 10.8 or later
