Overview

ISPH is a cross-platform computational fluid dynamics (CFD) library for mesh-free particle based simulation and visualization of incompressible flows using Smoothed Particle Hydrodynamics (SPH) methods. The library is open source and cross-platform, written in pure C++ and the new standard for parallel programming of modern processors - OpenCL. The library will make full use of GPUs, CPUs and other OpenCL enabled devices in running system to accelerate the computing to the maximum.

Note: This is a temporary website that contains basic information about the project. Complete website is under preparation along with the first public milestone release.

Features / Roadmap

System
 ■ cross-platform library, tested on Windows and Linux
 ■ parallel computation on CPUs, GPUs, etc.
 ■ distributed computation on multiple systems
 ■ highly optimized, clean and Doxygen-documented source code
 ■ GPL version 3.0 license

State Of The Art SPH
 ■ truly incompressible flow with different kinds of pressure solvers
 ■ different kinds of SPH smoothing kernels
 ■ anti-clumping and smooth particle movement
 ■ different kinds of time stepping and projection methods
 ■ CFL conditions for max allowed variable time-step
 ■ kernel gradient correction
 ■ multi-phase fluids

Boundary
 ■ wall boundaries
 ■ periodic boundary conditions
 ■ inflow and outflow boundary conditions

Geometry
 ■ multiple objects interacting with fluid
 ■ floating objects
 ■ collection of 2D and 3D primitives
 ■ import arbitrary 3D polygonal models
 ■ controllable motions of objects (with analytic expressions or data-set of velocity and/or positions in time)

Setup & Export
 ■ load and setup whole simulation through XML with easy syntax
 ■ export simulated data with constant time step and/or at specified simulation time
 ■ different kinds of export formats: VTK, comma separated, probes

Visualization
 ■ GUI for visual simulation setup pre-processing
 ■ interactive rendering of simulated data on the fly

Verification / Gallery

Soon.
