Decided by: Education Board E
Date of Decision: 2013-04-17

## General Information

Main field: Technology.
Elective Compulsory for: M3
Elective for: E4, M4-fo, M4-pu, M4-bem, MD4, N4
Language of instruction: The course will be given in Swedish

## Aim

The aim of the course is to provide a method for the solving of physical problems that are described by partial differential equations. The project in the course aim at giving the student an experience and theoretical understanding in solving comprehensive physical problems using the finite element method.

## Learning outcomes

Knowledge and understanding
For a passing grade the student must

• understand the derivation of the finite element method for linear problems
• understand how the finite element method is applied to linear problems
• understand the differences between balance laws and constitutive laws
• understand the differences between different boundary conditions and how they are implemented

Competences and skills
For a passing grade the student must

• be able to transform the strong form of a differential equation to the weak form
• be able to establish the finite element formulation from the weak form
• have the knowledge to write a finite element program
• be able to implement boundary conditions

Judgement and approach
For a passing grade the student must

• have the ability to analyse, to model and to simulate linear structures with the finite element method, as well as interpret the results
• have the understanding that different technical and physical problems can be modelled and simulated with the same numerical tools

## Contents

• Discrete systems.
• Strong and weak formulation of differential equations.
• Approximating functions.
• Weighted residual methods and Galerkin’s method.
• Finite element formulation of heat conduction.
• Finite element formulation of elastic bodies.
• Finite element formulation of torsion and bending.
• Isoparametric elements and numerical integration.

## Examination details

Assessment: The examination of the course consists of an assignment and a final written exam .The final mark will be based on the results from both parts. The assignment will be marked with failed or passed. The written examination will be marked with failed or passed with grades from 30-60. The final mark will be based on the grades divided with10. Less than 3.0 points is failed, 3.0 - 3,9 will give the mark 3, 4,0 - 4,9 will give the mark 4 and 5,0 and more will give the mark 5.
