console to calculate airflow around an airfoil based on RANS approach
RANSFOIL is a console program to calculate airflow field around an isolated airfoil in low-speed, subsonic, transonic or supersonic regime by numerically solving the Reynolds averaged Navier-Stokes (RANS) equations using mature computational fluid dynamics (CFD) method. As postprocess results, the aerodynamic parameters of the airfoil, e.g., lift coefficient and drag coefficient, can be integrated from the airflow distribution near wall boundary. In addition, the coupling between airflow and heat transfer and the effect of surface roughness on near wall flow are considered by this program, it can be used for engineering calculation of the friction drag and heat transfer coefficients on airfoil surface. RANSFOIL reads airfoil coordinates from a 1D XYZ file as only input, then outputs grid and solution files in 2D PLOT3D format to record grid coordinates and airflow data and a report file to show aerodynamic parameters.
Parallel finite element analysis
ParaFEM is an open source platform for parallel finite element analysis. The source code and philosophy are documented in the text book Smith, Griffiths and Margetts, "Programming the Finite Element Method", 5th Edition, Wiley, 2014. The software is written in modern Fortran and uses MPI for message passing.
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).

FE simulation based automatic global optimisation in modern Fortran
A collection of Fortran 2003, 90 and 77 routines, modules and programs for automatic simulation based global constrained optimisation. The initial application is for FE simulation of elasto-plastic buckling of steel rods aimed at tuning the hardening model. Unix shell scripts are used extensively. High concurrency is achieved with parallel multi-start global search and with parallel MPI FE. Powell's BOBYQA or LINCOA are used (not included in this package). Automatic mesh generation of 3D cylinders is provided + automatic boundary conditions, all via Fortran and shell scripting.
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.

Application Integration for HPC Multiphysics
The OpenMultiphysics project is the home for community-driven development of application integration technologies designed to aid in the design and implementation of multiphysics simulation capabilities. Design and development in this project is driven by the Consortium for Open Multiphysics. Feel free to visit us at our GitHub site as well: https://github.com/IllinoisRocstar/IMPACT
FLENS (Flexible Library for Efficient Numerical Solutions) is a C++ library for scientific computing. It can be considered as a very convenient and --- at the same time --- extremely efficient interface for BLAS and LAPACK. But it is much more than this
A free Fortran 2008, 2018 coarrays course with notes and exercises
Coarrays are native Fortran means for SPMD parallel programming. At runtime multiple copies of the executable (called images) are executing asynchronously. The F2008 standard provides coarray syntax, remote calls, coarray data objects, allocatable coarrays, syncronisation, atomics, etc. F2018 adds new functionality, e.g. collectives, teams, events, more atomics. Coarrays are used extensively in CASUP library for HPC (https://cgpack.sourceforge.io). The course is aimed at experienced Fortran users. Working knowledge of Fortran is assumed. The course is designed for a 1 day study with an instructor. Multiple exercises with full solutions are accompanied by notes. This course is taught to the University of Bristol HPC users. Exercises have been verified with Intel and GCC/OpenCoarrays. All course materials are released under BSD license. We welcome contributions, provided you are happy to release your work under BSD license. We welcome comments and problem reports.
Stress intensity factor (SIF) calculation from crack tip displacements
The code implements Muskhelishvili's complex function approach to calculate 2D stress intensity factors (modes I+II) from crack tip displacement fields. Surface displacements can be used with a plane stress elastic model. The code uses power/Fourier series expansion and a conformal mapping of an ellipse onto a circle.
GridPACK is a community-developed open-source collection of code for use in power systems research, analysis, and operation.
Fortran codes for SCNURS method - Side Cut Non-Uniform Residual Stress
SCNURS - Side Cut Non-Uniform Residual Stress measurement method for plates, - is a destructive RS measurement method developed in Moscow, Russia and later in Bristol, UK. The method is specifically designed for the measurement of highly non-uniform RS fields, including discontinuities, in plates. This project collects all codes which implement forward and inverse solution to the RS problem. The codes are in modern Fortran with OpenMP. The codes are distributed under 2-clause BSD license. The code uses Lapack (http://netlib.org/lapack), Slatec (http://www.netlib.org/slatec) and CMLIB (http://gams.nist.gov/cgi-bin/serve.cgi/Package/CMLIB) libraries. All these libraries are available as packages on FreeBSD. Another project page: http://eis.bris.ac.uk/~mexas/scnursweb
