Homogenization based two-scale modelling of ionic transport in fluid saturated deformable porous media
Jana Turjanicová, Eduard Rohan, Vladimír Lukeš
The paper deals with the homogenization of deformable porous media saturated by two-component electrolytes. The model relevant to the microscopic scale describes steady states of t…
Homogenization of the vibro-acoustic transmission on perforated plates
Eduard Rohan, Vladimír Lukeš
The paper deals with modelling of acoustic waves which propagate in inviscid fluids interacting with perforated elastic plates. The plate can be replaced by an interface on which t…
The Biot-Darcy-Brinkman model of flow in deformable double porous media; homogenization and numerical modelling
Eduard Rohan, Jana Turjanicová, Vladimír Lukeš
In this paper we present the two-level homogenization of the flow in a deformable double-porous structure described at two characteristic scales. The higher level porosity associat…
Multiscale finite element calculations in Python using SfePy
Robert Cimrman, Vladimír Lukeš, Eduard Rohan
SfePy (Simple finite elements in Python) is a software for solving various kinds of problems described by partial differential equations in one, two or three spatial dimensions by…
Homogenization of the fluid-saturated piezoelectric porous media
Eduard Rohan, Vladimír Lukeš
The paper is devoted to the homogenization of porous piezoelectric materials saturated by electrically inert fluid. The solid part of a representative volume element consists of th…
Modelling large-deforming fluid-saturated porous media using an Eulerian incremental formulation
Eduard Rohan, Vladimír Lukeš
The paper deals with modelling fluid saturated porous media subject to large deformation. An Eulerian incremental formulation is derived using the problem imposed in the spatial co…
Modeling of the contrast-enhanced perfusion test in liver based on the multi-compartment flow in porous media
Eduard Rohan, Vladimír Lukeš, Alena Jonášová
The paper deals with modeling the liver perfusion intended to improve quantitative analysis of the tissue scans provided by the contrast-enhanced computed tomography (CT). For this…
Numerical simulation of liver perfusion: from CT scans to FE model
Vladimír Lukeš, Miroslav Jiřík, Alena Jonášová +3
We use a collection of Python programs for numerical simulation of liver perfusion. We have an application for semi-automatic generation of a finite element mesh of the human liver…
Ultrafast Photo-Induced Charge Transfer Unveiled by Two-Dimensional Electronic Spectroscopy
Oliver Bixner, Vladimir Lukes, Tomas Mancal +9
The interaction of exciton and charge transfer (CT) states plays a central role in photo-induced CT processes in chemistry, biology and physics. In this work, we use a combination…
Vibrational wave packet induced oscillations in two-dimensional electronic spectra. II. Theory
Tomas Mancal, Alexandra Nemeth, Franz Milota +3
We present a theory of vibrational modulation of two-dimensional coherent Fourier transformed electronic spectra. Based on an expansion of the system's energy gap correlation funct…
Vibrational wave packet induced oscillations in two-dimensional electronic spectra. I. Experiments
Alexandra Nemeth, Franz Milota, Tomas Mancal +4
This is the first in a series of two papers investigating the effect of electron-phonon coupling in two-dimensional Fourier transformed electronic spectroscopy. We present a series…
