FleCSPH is a multi-physics compact application that exercises FleCSI parallel data structures for tree-based particle methods. In particular, FleCSPH implements a smoothed-particle hydrodynamics (SPH) solver for the solution of Lagrangian problems in astrophysics and cosmology. This wiki page provides description of different aspects of the code to various degree of detail.
For the latest static version of wiki please refer here. However, the static version may not be up-to-date with the wiki, so we recommend to refer to the wiki itself for the most recent updates.
-
Basic description, installation instructions and tests are given in README.

We provide several examples to help starting with FleCSPH. These examples represent typical tests of hydrodynamics and hydrodynamics coupled to gravity. The links below lead to the detailed descriptions for each example. To run these examples, FleCSPH must be built first -- please follow instructions given in our README to congifure and build the code.
