Attention V2 is now Online:

Simple 2D SPH Simulator with some special functions. It's possible to load data with two different methods. One based on geometry objects, the second one on placing every SPH particle on it's own.

It's possible to save simulations and to restart calculations from this safepoints. A tempSave-file is written to restart simulations, if they crash from an earlier point.

Now in v2 an example is added with a FEM beam and a moving piston. Both are hardcoded in the code and must be changed if you want to use it otherwise.

Now it can be used only 1 bar and 1 piston, for future it will be changed.

Video of textcase:

Software is tested and runs stable with up two 5000 SPH particles.

Known Problems:

If there are more than 15000-20000 SPH particles, after some simulationssteps the calculation slows down and gains all memory. Currently I have no idea why!


  • Smoothed particle hydrdynamics simulator
  • Save and load function for simulations
  • Possibility of showing simulation during calculation

User Reviews

  • For starting SPH simulation or simple testing of own methods, this C# Code offers what you want. It's a framework for people which are familiar with C# coding and SPH. If you just want to play around with SPH you should use another software. This is mor for scientific testing and learning of SPH. Well done work!
