Vmesnik za prenos geometrije in obremenitev za vezane računalniške simulacije z Abaqusom

magistrsko delo

Abstract

V okviru magistrskega dela je bil razvit vmesnik za prenos geometrije in obremenitev za vezane računalniške simulacije s programskim paketom Abaqus. Vmesnik je osnovan na izmenjavi podatkov o geometriji in obremenitvah med programom Abaqus in poljubno programsko kodo s pomočjo uporabniških podprogramov VUFIELD in VUAMP v programskem paketu Abaqus. Vmesnik lahko uporabimo za vezane simulacije različnih fizikalnih pojavov, pri katerih je obremenitveno stanje odvisno od geometrije. Za verifikacijo so predstavljeni trije testni primeri, kjer je analiziran pravilen prenos obremenitev in ohranitev energije. S testnimi primeri je ovrednotena tudi učinkovitost vmesnika. V nadaljevanju je predstavljeno delovanje vmesnika na primeru obremenjevanja konstrukcije napolnjene s porozno APM strukturo, katere obremenitveno stanje se preračunava v ločeni programski kodi. Nakazane so tudi možnosti za nadaljnji razvoj in uporabo tega vmesnika.

Secondary title:	Geometry and load transfer interface for coupled computational simulations with Abaqus
Secondary abstract:	In this master work interface for geometry and load transfer for coupled computational simulations with Abaqus was developed. Interface is based on data exchange on the geometry and loads between Abaqus and any other program code with user subroutines VUFIELD and VUAMP. We can use this interface for coupled computational simulations for many physical phenomenon in which the load state depending on the geometry. Verification and effectiveness analysis of interface are based on three simple examples. The following is also present test case of sphere impact on porous sandwich structure made from APM elements. Possibilities for further development and use are suggested.
