Model definition for 3D phenomena describing microclimate through the use of devices for automatic environment’s detection

Within the limits of the productive activity, the optimization of the micro-environment concerning a building utilisation can make use of new technical opportunities. The phases of planning and/or checking can be visualized and especially repeatedly modified through devices and software able to carry out 3D models. In these models, the physical-geometrical parameters or the peculiar features of the buildings can be changed and the resulting micro-environment aspects can be directly detected. The more and more close integration between CAD modelling environments and CAE analysis tools allows, on one hand, to modify the geometry by a close control of the size and the geometrical characteristics, and, on the other hand, it allows CAE system to evaluate the effects of different geometric forms or physical parameters on the analyzed micro-environment. In the agro-livestock field there are countless situations called “dynamic situations”. They need a plan of the micro-environment able to take into account the use-changing during each productive cycle. If the study concerns one existing environment, it is necessary to make measures by geometrical instruments or by optional technologies such as the photogrammetry. It allows recreating geometrical details on real scale from high-quality digital photos. The consequent geometrical model can be parameterised subsequently in a CAD environment and transferred to the analysis one for a fluiddynamics study. The geometrical model of the studied environment has been rebuilt by the use of the close photogrammetry software PhotoModeler®. The numerical analysis has been carried out by the multiphysics simulation software Comsol®.
