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 efficient, open source, iterative ISPH scheme
Abhinav Muta, Prabhu Ramachandran, Pawan Negi
In this paper a simple, robust, and general purpose approach to implement the Incompressible Smoothed Particle Hydrodynamics (ISPH) method is proposed. This approach is well suited…
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…
