Welcome to the cosmological hydrodynamical code ______ _________________ / ___/ | / / _/ ___/_ __/ \__ \| | /| / // // /_ / / ___/ /| |/ |/ // // __/ / / /____/ |__/|__/___/_/ /_/ SPH With Inter-dependent Fine-grained Tasking Website: www.swiftsim.com Twitter: @SwiftSimulation See INSTALL.swift for install instructions. Usage: swift [OPTION] PARAMFILE Valid options are: -a Pin runners using processor affinity -c Run with cosmological time integration -d Dry run. Read the parameter file, allocate memory but does not read the particles from ICs and exit before the start of time integration. Allows user to check validy of parameter and IC files as well as memory limits. -e Enable floating-point exceptions (debugging mode) -f {int} Overwrite the CPU frequency (Hz) to be used for time measurements -g Run with an external gravitational potential -G Run with self-gravity -s Run with SPH -t {int} The number of threads to use on each MPI rank. Defaults to 1 if not specified. -v [12] Increase the level of verbosity 1: MPI-rank 0 writes 2: All MPI-ranks write -y {int} Time-step frequency at which task graphs are dumped -h Print this help message and exit See the file examples/parameter_example.yml for an example of parameter file.

Fixed the minimal SPH hydro version Fix to #148. The code now runs without segfaulting when using the minimal SPH hydro code. Results are not great (by design) as the model is really poor (but simple). Changes are: - A missing initialisation in `engine_init_particles()`. - A mistake in the calculation of the du/dt term.
