settleDyn

settleDyn is a sedimentation process simulator. It is capable of generating loose sand-like structures from given particle forms and statistical distributions.

This software is a complete rewrite of the Settle3D program written by Guido Blöcher. See corresponding [paper] BZ08 for further details.

The complete sedimentation process including diagenesis involves many processes on variing time and space scales. The first step in sandstone formation is deposition of grains. This process can be simulated with current software. Cementation and further compactification or any other diagenetic processes cannot be simulated with settleDyn.

Simulation process starts with definition of grain shapes and grain size distributions. The shapes are polyhedral descriptions read from files in Geomview Object File Format ([.off] G07). For now, only convex shapes are allowed.

After the simulation is finished, the grains in their current positions are written to specified directory, again in the .off format.

Requirements

This code is written in Haskell and uses the Bullet Game Physics Engine Library for collision detection. In order to compile this program you will need:

Feature development

In near future I shall rewrite same functionality in c++. This will make compilation and modifications easier.

Possible new features are:

  • More statistical information
  • Other output format interesting especially for very large simulations.
  • Handling concave grains.
  • Randomization of grains' surfaces.
  • ...

Any suggestions are welcome.
