Application of Generalized Finite Difference Method for Nonlinear Analysis of the Electrothermal Micro-Actuator [PDF]

open access: yesMicromachines
In this work, the generalized finite difference method (GFDM), a popular meshless numerical method, is employed for predicting the thermal and mechanical behavior of an electrothermal micro-actuator. Based on the concept of GFDM and discretization on the

Accelerated Training of Physics Informed Neural Networks (PINNs) using Meshless Discretizations [PDF]

open access: yesNeural Information Processing Systems, 2022
We present a new technique for the accelerated training of physics-informed neural networks (PINNs): discretely-trained PINNs (DT-PINNs). The repeated computation of partial derivative terms in the PINN loss functions via automatic differentiation during

Stable Vortex Particle Method Formulation for Meshless Large-Eddy Simulation [PDF]

open access: yesAIAA Journal, 2022
A novel formulation of the vortex particle method (VPM) is developed for large-eddy simulation (LES) in a meshless scheme that is numerically stable. A new set of VPM governing equations are derived from the LES-filtered Navier–Stokes equations.

A meshless method to compute pressure fields from image velocimetry [PDF]

open access: yesMeasurement science and technology, 2021
We propose a meshless method to compute pressure fields from image velocimetry data, regardless of whether this is available on a regular grid as in cross-correlation based velocimetry or on scattered points as in tracking velocimetry.
