Sažetak
The complexity of geological materials makes it a huge challenge to simulate geo-engineering processes reliably. Powerful simulation tools that manage to handle their discontinuous nature are rare. Most are proprietary software where the black-box workings and major investment needed can be a block to researchers and teachers. VGeST is a suite of freely available Open Source simulation tools based on probably the most powerful discontinuum modelling approach, i.e. FEMDEM, that can easily take advantage of the versatile graphical user interface (GUI) functionality of leading, yet affordable proprietary preprocessing. The user effort in building input files for the 2D and 3D FEMDEM solvers is minimized through interactively completing drop-down templates and use of meshing tools in the pre-processor. In this paper we provide an overview of the motivation for VGeST, a taste of the working environment of VGeST, and an illustration of the power of codes Y2D and Y3D to tackle stresses and displacements in blocky or layered systems as well as problems of a granular nature which benefit from VGeST's inclusion of a shape library of virtual particles, P3D.
