The Neural Particle Method - An Updated Lagrangian Physics Informed Neural Network for Computational Fluid Dynamics [PDF]
Computer Methods in Applied Mechanics and Engineering, 2020 Numerical simulation is indispensable in industrial design processes. It can replace expensive experiments and even reduce the need for prototypes. While products designed with the aid of numerical simulation undergo continuous improvement, this must ...

Simplified unified wave-particle method with quantified model-competition mechanism for numerical calculation of multiscale flows. [PDF]
Physical Review E, 2020 A quantified model-competition (QMC) mechanism for multiscale flows is extracted from the integral (analytical) solution of the Boltzmann-BGK model equation.

A particle method for the homogeneous Landau equation [PDF]
Journal of Computational Physics: X, 2019 We propose a novel deterministic particle method to numerically approximate the Landau equation for plasmas. Based on a new variational formulation in terms of gradient flows of the Landau equation, we regularize the collision operator to make sense of ...

A Coarse Grained Model for Viscoelastic Solids in Discrete Multiphysics Simulations
ChemEngineering, 2020 Viscoelastic bonds intended for Discrete Multiphysics (DMP) models are developed to allow the study of viscoelastic particles with arbitrary shape and mechanical inhomogeneity that are relevant to the pharmaceutical sector and that have not been ...

Bayesian inference of a non-local proliferation model
Royal Society Open Science, 2021 From a systems biology perspective, the majority of cancer models, although interesting and providing a qualitative explanation of some problems, have a major disadvantage in that they usually miss a genuine connection with experimental data. Having this

Journal of Advances in Modeling Earth Systems, 2021 We develop a generalized interpolation material point method (GIMPM) for the shallow shelf approximation (SSA) of ice flow. The GIMPM, which can be viewed as a particle version of the finite element method, is used here to solve the shallow shelf ...

Boundary integral based polygon wall representation in the MPS method
Nihon Kikai Gakkai ronbunshu, 2018 The particle methods are suited to simulate fluid flow problems with large boundary deformation. The moving particle semi-implicit (MPS) method is one of the representative particle methods for incompressible flow.

Study on the Damping Effect and Mechanism of Vertical Slotted Screens Based on the BM-MPS Method
Journal of Marine Science and Engineering, 2023 Liquid sloshing is a common phenomenon in ocean engineering, and one which not only affects the stability of ship navigation, but also poses a threat to both the marine environment and human life.
