What is OpenFDEM#
OpenFDEM is an open-source(free) and object-oriented finite and discrete element solver for solving diverse multiscale,
multiphase and multiphysics (3M) problems accurately with high performance computations. Its applications include but
are not limited to mechanical, thermal and fluid dynamics. OpenFDEM also provides a wide range of flexibility in
geometry, mesh and material modules. OpenFDEM
is constructed by C++, and can be operated with an extensive Python C++ interface.
OpenFDEM
is open-free (first stage) or open-source (second stage) under GNU license and can be used even in comercial softwares as it is before properly get the copyright from
the developer.
Call for papers#
We would like to invite you to submit a contribution to a featured journal issue on FDEM that will be published on J. Rock Mech. Geotech. (Impact Factor = 7.3, ranking 2/41 in Engineering and geological) in 2024.
https://www.sciencedirect.com/journal/journal-of-rock-mechanics-and-geotechnical-engineering.
The combined hybrid finite-discrete element method (FDEM) is widely used for modeling fracturing and fragmentation processes in brittle materials such as rock and concrete. The intrinsic advantage of FDEM derives by its ability to combine continuum mechanics formulations, such as finite strain-based deformability and non-linear fracture mechanics, with discrete element method, allowing the seamless transition from a continuum to a discontinuum model. FDEM allows to model multiple crack initiation, propagation and nucleation at micro scale to fractures or fragments at macro scale. These advances promote the applications of FDEM in geomechanics, energy storage, geothermal energy extraction, rock engineering, oil and gas exploration and mining. In recent decades, the FDEM has matured into a more general-purpose numerical method, covering mechanical, hydraulic, thermal and chemical coupling, that can be used to tackle increasingly more complex multiphase, multiphysics and multiscale problems.
This Special Issue aims to highlight the new advances and future developments of combined finite-discrete element method or continuum-discontinuum method, for fracturing and fragmentation in geomechanics, underground energy storage, nuclear waste disposal, enhanced geothermal system, civil engineering or mining. All the papers on this special issue will be open access and free.
