Algorithms for uniform particle initialization in domains with complex boundaries
Pawan Negi, Prabhu Ramachandran
Accurate mesh-free simulation of fluid flows involving complex boundaries requires that the boundaries be captured accurately in terms of particles. In the context of incompressibl…
PySPH: a Python-based framework for smoothed particle hydrodynamics
Prabhu Ramachandran, Aditya Bhosale, Kunal Puri +17
PySPH is an open-source, Python-based, framework for particle methods in general and Smoothed Particle Hydrodynamics (SPH) in particular. PySPH allows a user to define a complete S…
An improved non-reflecting outlet boundary condition for weakly-compressible SPH
Pawan Negi, Prabhu Ramachandran, Asmelash Haftu
Implementation of an outlet boundary condition is challenging in the context of the weakly-compressible Smoothed Particle Hydrodynamics method. We perform a systematic numerical st…
Dual-Time Smoothed Particle Hydrodynamics for Incompressible Fluid Simulation
Prabhu Ramachandran, Abhinav Muta, Ramakrishna Mokkapati
In this paper we propose a dual-time stepping scheme for the Smoothed Particle Hydrodynamics (SPH) method. Dual-time stepping has been used in the context of other numerical method…
Entropically Damped Artificial Compressibility for SPH
Prabhu Ramachandran, Kunal Puri
In this paper, the Entropically Damped Artificial Compressibility (EDAC) formulation of Clausen (2013) is used in the context of the Smoothed Particle Hydrodynamics (SPH) method fo…
