sph-lite

sph-lite is Phase I of my master's level project with Tobias Weinzierl, "Mini-SPH".

The aim of Phase I is to develop a very simple test-bed SPH code that can be later integrated into the HPC software Peano.

Usage (Linux only):

• Clone repository.
• Compile code with make in the repo folder (If you don't have clang++ then change CXX)
  • Alternatively run make parallel to compile with OpenMP parallelism
• Generate simulation initial conditions.
  • See cases dir for examples of python scripts which calculate the initical positions of particles.
  • Python script generates a .case file which is referenced by the setup file (see next bullet point)
• Create a setup file (see sedov.dat, stationary.dat and dambreak.dat for reference).
• Run simulation with ./sph-lite.exe <setup file>

SPH Kernels implemented:

• Cubic spline

SPH schemes:

• Weakly Compressible SPH
• "Thermo SPH", using an ideal gas equation of state that incorporates internal energy

Particle types:

• Fluid
• Boundary - non-moving particles acting as rigid boundaries (see dambreak example)

Boundary conditions:

• Periodic
• Destructive (destroy particles which leave the domain)
