DiffSPH

Our fully differentiable SPH solver that can do it all just got its first public beta release!

Included in doing it all is:

• δ-SPH and δ+-SPH for weakly compressible simulations
• IISPH and DFSPH for incompressible simulations
• CompSPH, CRKSPH, PESPH and the classic Monaghan scheme for compressible simulations
• mDBC boundary conditions for rigid bodies
• Inlets and Oulets with buffer zones
• Periodic BCs using minimum image conventions
• Neumann and Dirichlet BCs
• grad-H, kernel renormalization and CRK correction schemes
• δ+ and implicit particle shifting
• Monaghan and Owen schemes for adaptive particle support radii
• Balsara, Morris, Rosswog, Cullen Dehnen artificial viscosity switches
• Sub particle scale turbulence modelling
• Differentiable generation of initial conditions using SDFs
• Hierarchical and compact hashing based neighbor searching
• Verlet lists for neighborhood searches
• Most Common SPH Kernel Functions (Wendland, B-Spline, Poly6) used across the fields

You can also:

• Solve inverse problems
• Use loss based physics
• Parameter estimation
• Shape optimization
• Closure Modelling
• … and much more
