How to train your solver: A method of manufactured solutions for weakly-compressible SPH
Pawan Negi, Prabhu Ramachandran
The Weakly-Compressible Smoothed Particle Hydrodynamics (WCSPH) method is a Lagrangian method that is typically used for the simulation of incompressible fluids. While developing a…
Techniques for second order convergent weakly-compressible smoothed particle hydrodynamics schemes without boundaries
Pawan Negi, Prabhu Ramachandran
Despite the many advances in the use of weakly-compressible smoothed particle hydrodynamics (SPH) for the simulation of incompressible fluid flow, it is still challenging to obtain…
Efficient and Accurate Adaptive Resolution for Weakly-Compressible SPH
Abhinav Muta, Prabhu Ramachandran
In this paper we propose an accurate, and computationally efficient method for incorporating adaptive spatial resolution into weakly-compressible Smoothed Particle Hydrodynamics (S…
A corrected transport-velocity formulation for fluid and structural mechanics with SPH
Dinesh Adepu, Prabhu Ramachandran
Particle shifting techniques (PST) have been used to improve the accuracy of the Smoothed Particle Hydrodynamics (SPH) method. Shifting ensures that the particles are distributed h…
SPINN: Sparse, Physics-based, and partially Interpretable Neural Networks for PDEs
Amuthan A. Ramabathiran, Prabhu Ramachandran
We introduce a class of Sparse, Physics-based, and partially Interpretable Neural Networks (SPINN) for solving ordinary and partial differential equations (PDEs). By reinterpreting…
