PDSTRIP is a hydrodynamic strip code for seakeeping. It computes ship motions for monohulls including sailing boats. PDSTRIP has been abandoned by its initiators, who do not wish to be contacted with use questions. The position of maintainer is vacant.

Zgoubi is a raytracing code. Since 1972 it pushes charged particles through accelerators and beam lines, by stepwise solution of Lorentz force equation - and their spins via Thomas-BMT differential equation. Zgoubi simulates beam dynamics and polarization in a variety of accelerators (storage ring, synchrotron, cyclotron, betatron, microtron, FFAG, multi-pass ERL, etc) and optical systems (beam lines, magnetic and electrostatic optical components, time-of-flight and mass spectrometers, etc). The code includes built-in fitting procedures with a wide variety of constraints; stochastic SR energy loss; the tracking of synchrotron radiation (SR) Poynting vector; space charge models; various Monte Carlo procedures, etc. Contact: francoisgmeot@gmail.com Documentation (History of accelerators that zgoubi deals with, theory, tutorials): https://link.springer.com/book/10.1007/978-3-031-59979-8 https://link.springer.com/book/10.1007/978-3-031-16715-7, Chap. 14.

A 2-D inviscid flow and adjoint solver on unstructured triangular grids. It makes use of a vertex-centroid finite volume scheme which is second order accurate. The adjoint solver is developed using the automatic differentiation tool called TAPENADE. Code has been moved to https://github.com/cpraveen/euler2d

HYP CFD is a structured, 3-D Navier-Stokes, MPI parallel multi-block computational fluid dynamics program for fluid thermophysics research, and high speed aerospace vehicle and propulsion applications.

Hy3S uses advanced MPI parallelized hybrid stochastic simulation methods to quickly compute the dynamics of biochemical networks with thousands of species/reactions. Many features included (see Home Page). An easy-to-use GUI (Matlab req) is included.

HydroSed2D is a two-dimensional numerical model for hydrodynamics and sediment transport on unstructured mesh.

Calculate electronic properties of graphene-like systems with a user friendly interface. The code uses the tight binding approximation and it is able to stude in a 0D, 1D and 2D geometries, orbital and magnetic fields, intrinsic and extrinsic spin-orbit coupling, sublattice imbalance, and interactions at the mean field level.

Rocstar is a multiphysics simulation application designed to do fluid-structure interaction (FSI) across moving, reacting interfaces. Rocstar couples multiple domain-specific simulation packages and disparately discretized domains and provides several simulation-supporting services including conservative and accurate data transfer, surface propagation, and parallel I/O. Rocstar is MPI parallel and routinely executes large simulations on massively parallel platforms. Rocstar was originally developed at the University of Illinois Center for Simulation of Advanced Rockets (CSAR) under Department of Energy ASCI funding. Ongoing development of Rocstar is conducted by Illinois Rocstar LLC with company IR&D and continued DOE SBIR funding.

Sandia National Laboratories’ (SNL) environmental assessment modeling tool helps optimize the design of MHK-turbine array layouts within ocean, tidal, and river systems to balance energy generation efficiency with environmental considerations. The new tool, SNL-EFDC, is an augmented version of US EPA’s Environmental Fluid Dynamics Code (EFDC) and includes; (1) a new module that simulates energy conversion (momentum withdrawal) by MHK turbine-like devices including commensurate changes in the turbulent kinetic energy and turbulent kinetic energy dissipation rate, (2) new, advanced sediment dynamics routines, and (3) augmented water quality modules. SNL-EFDC has been verified and validated against flume measurements of flow around sub-scale turbines and actuator disks.
