Development of a 3d dem simulation software for coupled simulations
ECMS 2024 Proceedings edited by Daniel Grzonka, Natalia Rylko, Grazyna Suchacka, Vladimir MityushevThis study is based on the development and methodology of building 3 dimensional discrete-, and finite element (DEM-FEM) simulation engines, as well as the potential way of improving usability and simulation speed. The program demonstrated here, BMEDEM3D, natively supports discrete element, finite element, and mass spring simulations.

Coupling Simulation for electrical resistance tomography
2016 IEEE International Conference on Imaging Systems and Techniques (IST), 2016The performance of electrical resistance tomography (ERT) system is usually investigated by numerical simulation or static tests using some simple phantoms. The objective of this paper is to construct a coupling simulation model for ERT. In this model, the distribution information of multi-phase flow is exchanged between the fluid field and electric ...

Continuum–Particle Coupling for Polymer Simulations
Journal of Chemical Theory and ComputationWe report a concurrent hybrid multiscale simulation method, in which a particle domain is coupled with a surrounding continuum domain. The particle domain consists of a coarse-grained model of poly(lactic acid) and the continuum domain is treated using the finite element method.

Coupling Problems in Microelectronic Device Simulation
1995The cost-effective design of electronic microstructures requires an advanced modeling and coupled simulation of various physical effects. The classical isothermal approach leads to the basic drift-diffusion model for semiconductor device simulation. In the stationary case, it represents a coupled nonlinear system consisting of a Poisson equation for ...

Coupled simulation of flow-structure interaction in turbomachinery
Aerospace Science and Technology, 2003Summary: A technique is presented which analyses the flutter behaviour of turbomachinery bladings in the time domain. The structural part of the governing aeroelastic equations is time-integrated according to the algorithm of Newmark, while the unsteady airloads are computed at every time step by a Navier--Stokes code.

Simulation of a complex sensor system using coupled simulation programs
Sensors and Actuators A: Physical, 1996The increasing complexity of microsystems, which include coupled partial systems basing on very different physical principles such as electronics, mechanics, optics or fluids, demands new modelling and simulation, -strategies. Especially to include the coupling effects Of such partial systems, in this paper a new simulation strategy is introduced. This

Efficient traffic simulator coupling in a distributed V2X simulation environment
Proceedings of the 3rd International ICST Conference on Simulation Tools and Techniques, 2010For the simulation of all aspects of V2X Communication scenarios, different simulators have to be combined and an interaction among them at runtime of the simulation has to be enabled. Hence, we have developed the V2X Simulation Runtime Infrastructure (VSimRTI) which couples discrete event-based simulators, e.g.

Enabling Coupled Scientific Simulations on the Grid
2006This paper addresses the problem of providing software support for simulating complex physical systems that require multiple physical models, potentially at multiple scales and resolutions and implemented using different programming languages and distinct parallel programming paradigms.

Parallel Simulation with a Generic Simulation Framework Featuring Loose Coupling
2005 International Conference on Parallel Processing Workshops (ICPPW'05), 2005For developing parallel systems composed of hard- and software, powerful simulation tools are needed in order to decrease time-to-market. With the generic simulation framework, clock-cycle accurate simulation for parallel devices communicating with each other is possible.

Feedback Effects in Simulated Stein’s Coupled Neurons
2005A network consisting of two Stein-type neuronal units is analyzed under the assumption of a complete interaction between the neurons. The firing of each neuron causes a jump of constant amplitude of the membrane potential of the other neuron. The jump is positive or negative according to whether the firing neuron is excitatory or inhibitory.
