This SPH code version is the basic version and incorporates the following features (remember to check Future developments for coming improvements). Version 2.0 has the following features:

2-D and 3-D versions
Variable timestep
Choice of time integration schemes: predictor-corrector, verlet, Beeman, symplectic
Choice of Kernel functions:
- Gaussian, Quadratic, Cubic Spline, Wendland Quintic
Kernel gradient correction
Choice of two types of solid boundary condition: dynamic and repulsive force
Periodic open boundary conditions in 2-D & 3-D
Choice of viscosity treatments:
- Artificial Viscosity
- Laminar Viscosity
- Sub-Particle Scale (SPS) Turbulence Model
Riemann solvers (ALE and non-ALE formulations)
Different Types of Moving Objects, forced and free motion:
- Floating Objects (free)
- Moving Gate (forced)
- Wavemaker (forced)
- Sliding Wedge (forced)
Visualization routines using Matlab or ParaView
Density Reinitialization using Shepard or Moving Least Squares (MLS)
RESTART option to stop and restart simulations,and checkpointing for clusters
Capability for different Equations of State
Choice of precision for Position variables (x,y,z): Single & Double
Support for compilers: GCC gfortran, INTEL ifort, Compaq Visual Fortran, Silverfrost FTN95

Other developments available in the future: (see Future developments)
