Here are some tools that I have developed over the years in order to do Shock Physics calculations. I hope you download and use them!
KO: One-Dimensional Lagrangian Hydrocode
Following code is from Mark Wilkins book. The code is a simple one-dimensional Lagrangian finite difference hydro-dynamic scheme, with von Mises strength. I have included several user selectable equations of state including ideal gas, Mie-Gruenisen and p-alpha. The code is written in fortran and the data can be visualized in octave or matlab. I have also made a couple of quick you-tube videos that show you how to compile, run and visualize the results.
This code will fill a given area (2D) or volume (3D) with circle or spherical shapes respectively. The seeds are placed in the domain either ordered or randomly and from those seeds the circles or spheres are grown. The objects can push each other around utilizing a penalty method, while they grow to efficiently fill the domain. The resulting realization can be exported in a variety of formats for use with hydrocodes. Mesogrow is written in fortran.
