Abstract [en]

This Master’s thesis is summery of a comparative study of 2 commercial CAD-integrated

FE-programs. These FE-programs were CATIA v5 and ABAQUS 6.3-7. The primary

objective of this study is to investigate the basic FEA capabilities of CATIA and

ABAQUS 6.7-3 in performing the linear static analysis and to identify whether there are

any differences and similarities between results the both Finite Element FE codes give.

The overall research question in the present thesis is: Do different FE programs, here

CATIA and ABAQUS, give the same results for FE analysis giving the same models if

subjected to the same boundary conditions? This research seeks to achieve its aims

through making a comparative qualitative study. Certain pre-selections were performed in

advance of conducting Finite element analysis and the comparison process to ensure that

results would reflect only the most relevant and meaningful differences and similarities

between the both FE-codes. Five different 3D solid models have been selected to perform

linear static Finite element analysis on. All these models (case studies) are created in

CATIA V5 and the linear static analysis conducted on using FE-codes CATIA v5 and

ABAQUS 6.7-3. Three static responses (results) of the linear static analysis have been

adopted as criteria for comparisons purposes. These criteria were: (1) displacements, (2)

Von Mises stress, and (3) principal stress. The results of comparisons showed that there is

a very good agreement in most cases and small gap between in a few cases. Results of

this study demonstrate that the both FE-programs CATIA v5 and ABAQUS 6.7-3 have

good capabilities to perform FE-analysis and they give very near results. Reason behind

differences is that each of them uses a different algorithm for solving problems. The final

answer for the research question is given with valuable recommendations for future work

in the scope of this research.
