    The FMI++ Library

    The FMI++ Library

    A High-level Utility Package for FMI-based Software Development

    The Functional Mock-up Interface (FMI) specification intentionally provides only the most essential and fundamental functionalities in the form of a C interface. On the one hand, this increases flexibility in use and portability to virtually any platform. On the other hand, such a low-level approach implies several prerequisites a simulation tool has to fulfill in order to be able to utilize such an FMI component. The FMI++ library addresses this problem for models and tools with interfaces according to the FMI specification by providing high-level functionalities, which ease the handling and manipulation of such models and tools. Furthermore, the FMI++ library provides utilities to implement FMI-compliant interfaces for a large class of simulation tools. The FMI++ library intends to bridge the gap between the basic FMI specifications and the typical requirements of simulation tools. It is distributed using a BSD-like license.

    abumpack

    abumpack

    Fortran library with the Abaqus user material subroutines UMAT/VUMAT

    This library contains several of user material subroutines for implicit quasi-static (UMAT) and explicit dynamic (VUMAT) versions of the Abaqus solver. The project web site: http://abumpack.sf.net. The Abaqus is a proprietary finite element (FE) code ( http://www.3ds.com/products-services/simulia/products/abaqus/). Users can write subroutines for use with the Abaqus. Linear elastic, isotropic hardening plasticity, Gurson-Tvergaard-Needleman (GTN), Rousselier constitutive models are provided. Quote this code as: A. Shterenlikht, N. A. Alexander, Levenberg-Marquardt vs Powell's dogleg method for Gurson-Tvergaard-Needleman plasticity model, Computer Methods in Applied Mechanics and Engineering 237-240:1-9 (2012).

    CASUP

    CASUP

    Cellular Automata library for SUPercomputers (CASUP)

    CASUP is a Cellular Automata (CA) library for HPC and supercomputers. It can be used in materials science (microstructure evolution, grain coarsening, fracture etc.), physics (Ising magnetisation) and for many other CA. If you use the library, please reference it as: A. Shterenlikht, L. Margetts, Three-dimensional cellular automata modelling of cleavage propagation across crystal boundaries in polycrystalline microstructures, Proc. Roy. Soc. A 471:20150039, DOI: http://dx.doi.org/10.1098/rspa.2015.0039. CASUP can be linked with FE (e.g. MPI FE library ParaFEM, http://parafem.org.uk) for a multi-scale multi-physics CA-FE framework. CASUP extensively uses Fortran 2008 and 2018 coarrays, as well as MPI, OpenMP and do concurrent. CASUP can be used with Cray, Intel and GCC/OpenCoarrays compilers. Scaling beyond 100,000 cores on Cray XC30 was demonstrated.

    Network Emulator

    Distributed Network emulation tool for high rate packet

    I need your help: In order to make this framework easier and more useful, I need your contribution. The idea behind this framework is to develop a GUI like GNS3 and make this framework more stable. So if you are interested and have C/C++ programming skills, please contact me at zahid.med@gmail.com This framework allows to emulate a network by managing ethernet packets coming from two kind of interfaces: UDP and virtual network card. This tool is similare to dynamips (GNS3) but it can manager a higher packet rate. It can help to study DDoS attacks based on Botnet using the Lightweigth C++ Virtual Machine (LwCVM) in order to emulate Bots. This project is based on the following projects and libraries: LightweighIP of the TCP/IP stack pthread libpcap for communication with virtual machines dynamips Linux MicroCore
