![]() ![]() The objective will be the implementing innovative air diffusion grilles in a prototype vehicle. The aim of this paper is to modeling and simulating the thermal comfort inside the vehicles, using COMSOL Multiphysics program, for different ventilation grilles. The environmental quality in vehicles is a very important aspect of building design and evaluation of the influence of the thermal comfort inside the car for ensuring a safe trip. Modeling of the thermal comfort in vehicles using COMSOL multiphysics Different parameters like beam displacement, electrostatics force and stress over the beam have been calculated by finite element method after having defining the geometry, the material of the cantilever model (fixed at one of ends but is free to move otherwise) and his operational space.« less In addition to the simplification of calculations, the weight of the cantilever was not taken intomore » account. In this paper, we present mechanical behavior of a cantilever actuated by an electrostatic force. ![]() This is why they require actuation under predetermined conditions, such as electrostatic force or inertial force. The cantilevers playing a key role in Micro Electro-Mechanical Systems (MEMS) devices (switches, resonators, etc) working under potential shock. This paper presents the studies of mechanical behavior of MEMS cantilever beam made of poly-silicon material, using the coupling of three application modes (plane strain, electrostatics and the moving mesh) of COMSOL Multi-physics software. Mechanical behavior simulation of MEMS-based cantilever beam using COMSOL multiphysicsĭOE Office of Scientific and Technical Information (OSTI.GOV) ![]() It can be concluded from the results of potential distribution and transmembrane voltage, it show that pores formation only occurs in the membrane cells and it could not penetrate into inside the model cell so there is not pores formation in its organells. Modeling of electroporation phenomenon on a model cell had been done by using software COMSOL Multiphysics 4.3b with the applied external electric field with intensity at 1.1 kV/cm to find transmembrane voltage and pore density. The purpose of creating pores in the cell using conventional electroporation are to increase the effectiveness of chemotherapy (electrochemotherapy) and to kill cancer tissue using irreversible electroporation. Modelling in conventional electroporation for model cell with organelles using COMSOL MultiphysicsĬonventional electroporation is a formation of pores in the membrane cell due to the external electric field applied to the cell. The paper will introduce using of the LiveLink for COMSOL for chosen case studies in the field of technical cybernetics and bioengineering. The cooperation with MATLAB via LiveLink enhances a powerful computational environment with complex multiphysics simulations. Once the minimum is found, it returns exit flag, terminates optimization and returns the optimized values of the parameters. Once the task is launches, the COMSOL model is being called in the iteration loop (from MATLAB environment by use of API interface), changing defined optimization parameters so that the objective function is minimized, using fmincon function to find a local or global minimum of constrained linear or nonlinear multivariable function. At first, the head script launches COMSOL with MATLAB and defines initial value of all parameters, refers to the objective function J described in the objective function and creates and runs the defined optimization task. It allows user to utilize the full power of MATLAB and its toolboxes in preprocessing, model manipulation, and post processing. LiveLink for COMSOL is a tool that integrates COMSOL Multiphysics with MATLAB to extend one's modeling with scripting programming in the MATLAB environment. Ozana, Stepan Pies, Martin Docekal, Tomas AlN nanowires exhibit a better piezoelectric response than LiNbO3 nanowires do.Ĭase studies on optimization problems in MATLAB and COMSOL multiphysics by means of the livelink The variation of the total maximum displacement as a function of applied force for various NWs lengths and the variation of the voltage as a function of applied force were plotted and discussed. The Finite Element Method (FEM) was used for solving the differential equations with various parameters such as size, length, force, etc. In this study, Lithium niobate (LiNbO3) and Aluminum nitride (AlN) nanostructures were designed and investigated using the COMSOL Multiphysics software for pressure sensing applications.
