finite element method (FEM)

The attached zip contains both data and analysis scripts for the first two particle-in-cell examples in the associated paper. In particular,

(1) The BeamExpansion folder contains output z vs r phase space data from the quasi-Helmholtz FEMPIC code used in the paper at 3 ns (fempic.csv), as well as the equivalent data from an XOOPIC simulation (xoopic.txt). The analysis is done in the ipython notebook file in the folder. All of the plots in the paper was generated using this same script.

This research focuses on simulating a transformer

using electromagnetic field solver software: FEMM and COMSOL

Multiphysics®. These tools are used to simulate and extract

the model of a three-winding transformer. The primary objective

of the extracted model is to predict key magnetic parameters,

such as leakage and magnetizing inductances. These inductances

play a critical role in switch-mode power converter topologies,

ensuring proper operation and achieving high efficiency through

The multi-effect fields in the grounded-wire source time-domain electromagnetic (TDEM) will be generated by complex physical characteristics and parameter information of polymetallic ore. The studies show that the induced polarization (IP) and magnetic viscosity (MV) effects are significant signs of polymetallic ore and have been proved t

We present a finite-element-based cohesive zone model for simulating the nonlinear fracture process driving the propagation of water-filled surface crevasses in floating ice tongues. The fracture process is captured using an interface element whose constitutive behavior is described by a bilinear cohesive law, and the bulk rheology of ice is described by a nonlinear elasto-viscoplastic model. The additional loading due to meltwater pressure within the crevasse is incorporated by combining the ideas of poromechanics and damage mechanics.
