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 The idea behind this goal is to introduce air diffusers with a special geometry allowing improving mixing between the hot or the cold conditioned air introduced in the cockpit and the ambient.Ĭase studies on optimization problems in MATLAB and COMSOL multiphysics by means of the livelink 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.
