GeoCalc (previously OSXGeoCalc) is a calculator for vectors (lines, planes, and oriented drillcore data), and tensors (strain and stress).
Structural geology deals to a great extent with the operation of vectors and tensors. GeoCalc (previously OSXGeoCalc) is a calculator for vectors (lines, planes, and oriented drillcore data), and tensors (strain and stress).
Lines and planes can be visualized in a stereonet, and strain and stress in a Mohr diagram. Multiple computations can be executed using text files. Besides being a great tool to learn the fundamental concepts of vectors and tensors and their application in structural geology, GeoCalc is a powerful tool to perform batch operations on thousands of vectors or tensors stored in text files.
GeoCalc was made for structural geologists, but it can be used by anyone interested in vectors and tensors. GeoCalc is freeware for non-profit, academic purposes. To use the program for consulting, please contact me
