Texto completo da fonteIn computer graphics, the physical phenomena simulated for the creation of animations, video games or the design of objects are found to be more and more complex:First, in terms of the computational cost, the scale of the simulations is more and more important;Then, in terms of the complexity of the phenomena themselves, which require the models to be able to change their state and shape.This growing complexity introduces new challenges in order to offer control on these large scale simulations to the user.In many cases, this control is reduced to a trial-and-error process in order to determine the parameters of the simulation which best meet the objectives of the user.In this thesis, we propose three techniques to tackle these challenges.First, we introduce a new adaptive model which allows to reduce the computational cost in Lagrangian simulations of particles.In contrast with re-sampling strategies, the number of degrees of freedom remains constant throughout the simulation.Therefore, the method is simpler to integrate into an existing simulator and the memory consumption remains constant, which can be an advantage in an interactive context.Then, we propose an algorithm which allows the detailed cutting of thin deformable objects.Our method relies on a dynamic update of the shape functions associated to the degrees of freedom, which therefore allows to keep a very low number of degrees of freedom while performing detailed topological changes.Finally, we focus on the control of the fluid animations and take inspiration from interactive methods of shape editing in the field of 3D modeling.We introduce a system where the user directly edits the result of the simulation, i.e. a sequence of meshes representing the surface of the fluid.We propose selection and editing spatio-temporal tools inspired from static shapes sculpting software

Texto completo da fonteUnderstanding and modeling phenomena governing stimuli release during food consumption make it possible to respect both nutritional and sensorial criteria during its formulation. A model of salt release during the course of mastication was developed for “solid” products. The breakdown was comprehended by the generation of the area of contact between the product and the saliva that governs the transfers of stimuli. The area of contact was written as the product of two functions. The first was related to the subject and was function of his masticatory performance. The second was related to the product and depended on its breakdown behavior that can be determined by in vitro tests. During the pharyngeal stage, the biomechanics of swallowing governs pharyngeal mucosa coating and aroma compounds present in this layer. These phenomena are due to a thin film flow, stationary in a soft elastohydrodynamic contact whose the kinematics is equivalent to a forward roll coating process lubricated by saliva. Two sets of conditions were distinguished. When the saliva film is thin, food bolus viscosity has a strong impact on mucosa coating and on flavour release. When the saliva film is thick, the food bolus coating the mucosa is very diluted by saliva during the swallowing process and the impact of product viscosity on flavour release is weak. This second set of condition allowed us to explain the physical origin of in vivo observations on flavour release

Texto completo da fonteThe purpose of this study is the time domain modeling and numerical simulation of a piano. We aim at explaining the vibratory and acoustical behavior of the piano, by taking into account the main elements that contribute to sound production. The soundboard is modeled as a bidimensional thick, orthotropic, heterogeneous, frequency dependant damped plate, using Reissner Mindlin equations. The vibroacoustics equations allow the soundboard to radiate into the surrounding air, in which we wish to compute the complete acoustical field around the perfectly rigid rim. The soundboard is also coupled to the strings at the bridge, where they form a slight angle from horizontal. Each string is modeled by a one dimensional damped system of equations, taking into account not only the transversal waves excited by the hammer, but also the stiffness thanks to shear waves, as well as the longitudinal waves arising from geometric nonlinearities. The hammer is given an initial velocity that projects it towards a choir of strings, before being repelled. The interacting force is a nonlinear function of the hammer compression. The final piano model that will be discretized is a coupled system of partial differential equations, each of them exhibiting specific difficulties (nonlinear nature of the string system of equations, frequency dependant damping of the soundboard, great number of unknowns required for the acoustic propagation), in addition to couplings' inherent difficulties. On the one hand, numerical stability of the discrete scheme can be compromised by nonlinear and coupling terms. A very efficient way to guarantee this stability is to construct a numerical scheme which ensures the conservation (or dissipation) of a discrete equivalent of the continuous energy, across time steps. A major contribution of this work has been to develop energy preserving schemes for a class of nonlinear systems of equations, in which enters the string model. On the other hand, numerical efficiency and computation time reduction require that the unknowns of each problem's part, for which time discretization is specific, hence different, be updated separately. To achieve this artificial decoupling, adapted Schur complements are performed after Lagrange multipliers are introduced. The potential of this time domain piano modeling is emphasized by realistic numerical simulations. Beyond greatly replicating the measurements, the program allows us to investigate the influence of physical phenomena (string stiffness or nonlinearity), geometry or materials on the general vibratory behavior of the piano, sound included. Spectral enrichment, " phantom partials " and nonlinear precursors are clearly revealed when large playing amplitudes are involved, highlighting how this approach can help better understand how a piano works

Texto completo da fonteElectron emission in vacuum from a cathode at high voltage is an important physical phenomenon for the study of vacuum breakdown or electron sources. In the vacuum breakdown, the first step of this mechanism is electron emission at the top of the microprotrusions on the surface. Microprotrusions or emitters in electron sources have the shape of a tip. A numerical model describing the thermo-field emission has been developed for a 2D axisymmetric tip. The problem is multi-physical and it is necessary to solve problems of different natures: quantum mechanics, electrostatic, electric current and thermal heating. With this model, it is possibleto study electron emission and vacuumbreakdown when nanosecond high voltage pulses are applied. Furthermore, the study of electron emission when a picosecond pulsed laser illuminates a high voltage cathode has been performed. A new model has been developped to describe the photo-electric effect and a two-temperature model has been implemented to describe the heating of the cathode in a non-equilibrium regime. Finally, the modeling of the interaction between microparticles and electron emission from microprotusions has been realised, in order to study the breakdown voltage. Different trajectories of microparticles have been identified based on the results, depending on the electron emission current
