Preservation of Adiabatic Invariants under Symplectic Discretization
, 2007 Symplectic methods, like the Verlet method, are a standard tool for the long term integration of Hamiltonian systems as they arise, for example, in molecular dynamics.

SPH Simulates Steep‐Stepped Spillway Flows Assessing Convergence, DDT Effects, and Pressure Accuracy
Chemical Engineering &Technology, Volume 49, Issue 4, April 2026.Numerical investigation of high‐gradient stepped spillway flows using the SPH method, highlighting the simulation setup and skimming flow regime. Convergence analysis compares results with and without the Density Diffusion Term (DDT), showing its effectiveness in reducing spurious oscillations.

Fortschritte der Physik, Volume 74, Issue 4, April 2026.ABSTRACT In this paper, we continue the development of the Cartan neural networks programme, launched with three previous publications, by focusing on some mathematical foundational aspects that we deem necessary for our next steps forward. The mathematical and conceptual results are diverse and span various mathematical fields, but the inspiring ...

Symplectic Structures on the Integration of Exact Courant Algebroids
, 2018 We construct an infinite-dimensional symplectic 2-groupoid as the integration of an exact Courant algebroid. We show that every integrable Dirac structure integrates to a “Lagrangian” sub-2-groupoid of this symplectic 2-groupoid.

Stable Symplectic Integrators for Power Systems [PDF]
, 2002 The paper illustrates the application of symplectic integrators obtained by composition for solving power system consisting of several machines. The multi-machine angular swings during and following fault conditions and clearing are investigated. Numerical results obtained using symplectic integrators were found to be comparable to those obtained using

Symplectic integration of hierarchical stellar systems
, 2003 Symplectic integration has been used successfully for many years now for the study of dynamics in planetary systems. This technique takes advantage of the fact that in a planetary system, the mass of the central body is much larger than all the other ...

Symplectic Integration of Bar Linkage Motion Equations
, 2016 학위논문 (석사)-- 서울대학교 대학원 : 기계항공공학부, 2016. 2. 조맹효.In this study, the motion and the qualitative behaviour of an unconstrained simple bar-linkage which is under the influence of different types of forces is studied. Standard non-symplectic integration methods
