New open-source ANSYS-SolidWorks-FLAC3D geometry conversion programs
Journal of Sustainable Mining, 2015 AbstractNumerical calculations are used increasingly often to obtain a stress-strain state in many engineering problems. A popular program for this type of calculation which makes use of the finite difference method (a continuous method) is Itasca's FLAC3D. However, an important limitation of FLAC3D is the difficulty of geometry creation.
