OpenMps

This project contains an implemention of Moving Particle Semi-implicit (MPS) method. MPS method is one of the most popular Particle Method to solve Continuum Dynamics (e.g. Fluid Dynamics). See Wikipedia for more information.

Usage

Build

0. Get Boost C++ Libraries and ViennaCL by yourself.
   • Boost should be installed in your system and includible by OpenMps. You can use NuGet Boost on Visual Studio.
   • ViennaCL should be placed on src/viennacl. You can use git submodule.
1. Build codes. It is recommended to use Visual Studio.

Execution

0. Run the program (Developers expect execution on Windows). Results will be output as CSV in "result" folder.
1. Visualize results. If you use ParaView 5.0 or later,
   1. Open "particle_****.csv"s
   2. Add "TablesToPoints" filter
      • X Column = x
      • Y Column = z
      • Z Column = x
      • Representation = Point Gaussian
      • Gaussian Radius = l_0/2
      • Shader Preset = Sphere
   3. Create new Layout (3D View)
   4. Make "TablesToPoints" visible
   5. You can see the motion of particles columns are:
      • x : horizontal value of position vector
      • z : vertical value of position vector
      • u : horizontal value of velocity vector
      • w : vertical value of velocity vector
      • p : value of pressure
      • n : value of particle number density
   6. or you can load ParaView State File "resultView.pvsm" for instance.
