RockFlow

from Wikipedia, the free encyclopedia

The computer program RockFlow was developed at the Institute for Fluid Mechanics and Electronic Computing in Civil Engineering (today: Institute for Fluid Mechanics and Environmental Physics in Civil Engineering) of the Gottfried Wilhelm Leibniz University of Hanover for the numerical simulation of underground processes. It is based on the finite element method . Based on the development of a groundwater model in the 1980s, the range of functions has been continuously expanded. Today, the focus of development is on the coupled simulation of hydraulic, mechanical and thermal processes.

Performance characteristics

  • Finite element simulation for DOS, WINDOWS, UNIX, LINUX
  • Graphical user interface for WINDOWS, LINUX
