Abstract [en]

The Finite Element Method (FEM) is a technique for finding the approximate solution

of differential equations. It is commonly used in structural analysis to evaluate the

deformation and internal stresses of a structure that is subject to outer loads. This

thesis investigates the Finite Element Analysis (FEA) workflow that is used at Andritz

Hydro AB, with the objective to find solutions that make the workflow more time

effective. The current workflow utilises Siemens NX and Salomé for pre- and

post-processing, and Code Aster as the FEM solver. Two different approaches that

improve the workflow are presented. The first suggest that the entire FEA workflow

is migrated to NX using the built-in FEM package of NX called Advanced Simulation.

The second approach utilises the Salomé API (Application Programming Interface) to

create a customised toolbox (a script containing several functions) that automate

several repetitive and cumbersome steps of the workflow, therefore effectively

reducing the time that is required by the analyst to perform FEA. Due to the positive

results and ease-of-use, the Salomé toolbox is preferred over the license cost and

steep learning curve that is related to NX and Advanced Simulation.
