SPH3D

3D Smoothed Particle Hydrodynamics FORTRAN code. Adapted from source in Smoothed Particle Hydrodynamics a meshfree particle method by G.R. Liu and M.B. Liu (2003). To aid building and analysis of results, a make system and several python scripts were created.

Linux:

Build:

>make

This command will execute the Makefile script. This script will create, if they don't already exist, the build, movie, and data directories. It will compile the FORTRAN, i.e. *.f and *.f90, files in the source directory and the link them to create the executable sph.x.

Clean:

There are 3 levels: clean, cleaner, sanitize. The commands to use them and what they do are as follows:

>make clean

This will delete the executable and the object files in the build directory.

>make cleaner

This will do clean plus delete the data files in the data directory.

>make sanitize

This will do cleaner plus remove the build, movie and data directories.

Execute:

>./sph.x

Scripts:

Currently, the scripts are focused on the 1D shock tube simulation. While they are specific to that problem, they do provide a starting point for adaptation and generalization to plot outputs to match the full capability of the SPH code.

plot_LaL_SPH_IF.py

Execute:

>python3 plot_LaL_SPH_IF.py

Plots the initial and final states of the shock tube simulation for velocity, pressure, density, and internal energy as a function of particle position.

plot_LaL_SPH_Movie.py

Execute:

>python3 plot_LaL_SPH_Movie.py

Creates an animated gif file and then plots movie of the time evolution of the shock tube simulation for velocity, pressure, density, and internal energy as a function of particle position.
