Modalna analiza v okviru odprtokodnih paketov Salome, SfePy in ParaView

Mišmaš, Gregor (author), Slavič, Janko (mentor)

V diplomski nalogi je predstavljena modalna analiza geometrijsko kompleksne strukture z uporabo treh odprtokodnih paketov Salome, SfePy in ParaView. Modalna analiza je bila najprej izvedena z metodo končnih elementov v okviru predstavljenih odprtokodnih paketov in potem še s komercialnim programom Siemens NX. Numerično dobljene rezultate smo primerjali z rezultati dobljenimi z eksperimentalno modalno analizo. Ugotovljeno je bilo, da se eksperimentalni in numerični rezultati dobro ujemajo. Glavna pomanjkljivost uporabe odprtokodnih paketov je občutno daljši čas računanja in zahtevnost uporabe.

• Title: Modal analysis using open source packages Salome, SfePy and ParaView

Abstract

Modal analysis of a geometrically complex structure using three open source packages Salome, SfePy and ParaView is presented in this diploma thesis. The modal analysis was first performed using the finite element method within the three open source packages and later with a commercial software Siemens NX. Numerically obtained results were then compared to the experimentally obtained ones and it was shown that the numerical and experimental results match well. The main disadvantages of using open source packages are slow calculation time, and difficulty of use.
