The deal.II tutorial step-54: using arbitrary CAD files to generate geometry-adapted triangulations

This program elaborates on concepts of industrial geometry, using tools that interface with the OpenCASCADE library (http://www.opencascade.org) that allow the specification of arbitrary IGES files to describe the boundaries of geometries. The tutorial shows how to use a CAD file and a coarse surface triangulation to generate CAD adapted triangulations (possibly with local refinement), using different projection strategies
