DEVELOPMENT OF A PARTICLE SYSTEM FOR VISUALIZATION OF AIRFLOW

To diplomsko delo proučuje gibanje zračnih tokov okoli objektov ter izvedbo njihovih simulacij. Na podlagi ugotovitev smo v modelirniku Cinema 4D ustvarili sistem inteligentnih delcev, ki simulira gibanje zračnih tokov. S pomočjo grafičnega programskega urejevalnika XPresso smo v navidezno okolje vpeljali fizikalne lastnosti in simulirali sile, ki delujejo na objekte v preizkusih okoljih resničnega sveta. V želji po čim bolj natančni upodobitvi smo uporabili različne metode upodabljanja. Izdelan sistem delcev je sicer podal zelo zadovoljive rezultate, ki pa bi lahko bili v primeru večje računske moči in ob večjem številu uporabljenih delcev občutno boljši. Iz tega razloga smo poiskali tudi alternativne rešitve, med katerimi izstopa vtičnik TurbulenceFD, katerega algoritem temelji na sprotnem reševanju Navier-Stokes enačb, s katerimi izračunavamo tok tekočin.In our diploma work, we have studied the airflow around objects and the ways of simulating them. Based on our findings, we have set up a thinking particle system, which simulates airflow. Within’ the XPresso editor, we have created an environment, which is able to take into account the forces that occur during real-life test in wind tunnels. To make the simulation as precise and realistic as possible, we used different approaches. Although the results given by the developed particle system are more than satisfying, there would still be room for improvement, for which a bigger computational power and amount of particles would be needed. In search of alternative solutions, we came across the TurbulenceFD plug-in, which implements a voxel-based solver, based on Navier-Stokes equations to simulate the flow of fluids
