Detailed Description

Settings via preprocessor directives, typedefs, constants, structs.

Many pre-processor directives are part of the implementation. The code can be used for simulations in one dimension, two dimensions and three dimensions via conditional compiling in dependence of the pre-processor directive DIM.

Warning: However, the code is currently not appropriately tested for DIM 1 and DIM 2 and therefore no statement about the functionality and correctness can be made at this point.

Most important are the flags GRAVITY_SIM and SPH_SIM which enable or disable the gravitational and SPH part of the code.

Author: Michael Staneker

Bug:: no known bugs

Todo:: remove deprecated flags and avoid flags that don't match
