Release Notes: This release adds new gravity solvers, a source term for stirring, a nuclear burning network, a directionally split 8wave MHD solver, and an equation of state for fully ionized plasma of arbitrary degeneracy. It also includes Lagrangian tracer particles for the uniform grid. API changes include complete interface definitions of the units' API, support for face-centered discretization variables, curvilinear geometry in the meshes, and more robust boundary conditions handling. Two methods of parallel I/O support have been added. New test cases have been added.
Release Notes: New features include cosmology routines. Improvements include better support for non-planar geometries (in mesh and artificial viscosity calculations) and extensive code cleanup. Optimizations include better timestep calculation and much improved multi-grid routines.
Release Notes: In this release, improvements include expanded documentation, internal and in the users guide, a cleaned-up code base, including better support for many compilers, better I/O with higher serial performance, extended data stored in the checkpoint files, and tools to convert output to TecPlot or ChomboVis formats, better support for non-Cartesian geometries, and much-improved gravity solvers. There are new features for the MHD and hydro (PPM) solvers, and support for cosmological expansion.
Release Notes: This release increases portability, improves modularity, includes additional new solvers and many additional test setups, provides cleaner interfaces, and reorganizes the framework to make it cleaner and more flexible. There are selected specific feature updates, including isolated boundary conditions for gravity, support for active particle dynamics and passive particle tracers, new and improved fidlr/xflash routines, and user contributed modules radiative cooling, static and gaussian transient heating, Spitzer viscosity and conductivity, and ionization.
Release Notes: This release contains many new features and bugfixes. The API was cleaned up. The program now compiles on a wider range of Intel Linux and Compaq compilers. New poisson solvers for gravity, a new burner, new comparison routines, and resistive MHD were added.
Release Notes: Some code cleaning and optimization will be done before FLASH 2.0 final is released, but this version has been heavily tested and is in use internally by the center. The new version includes the use of an API to access and store the solution variable, more physics modules, including MHD, self-gravity, and diffusion, new hydro solvers, a new setup script written in Python, support for HDF5, new fixes for bugs reported in FLASH1.61, improved configuration, and Improved and greatly expanded documentation.
Release Notes: This patch fixes several bugs, and contains no new features. Numerous questions were added to the FAQ.
