The solution is available in "It's learning". |

The evaluation of the project is now available in "It's learning". |

Questions before the exam. I'm available in my office from 2:15pm to 3pm tomorrow, 20th of May, for answering your questions. |

The curriculum for the exam is the last column of the table Schedule. |

Now you can hang your posters in the third floor. |

Poster in the third floor: Please wait before you hang any posters in the third floor; Martin Strand tells me that there will be some proper system to hang posters in short time. |

New material: you will find curriculum material on Finite Elements and the report on the meeting with the student-representatives on "It's learning". |

Lectures this and next week: All students who are not leaving for the excursion to China and plan to come to the lectures next Friday and next week, should send me an e-mail to confirm they will participate to the lectures. Thanks. |

Poster presentation Tuesday 5th of April at 14:00 in 1329 SBII. The posters should contain a summary of the project results, with figures and explanations printed in several A4 sheets or one big A0 sheet. The groups will be asked to present their poster to the people coming by: prepare a speech of no more than 5 minutes to present the results (all group members should say something), the listeners will typically ask you for more details about your work. Geir and Elena will go through all the posters, but also other people will come and have a look. |

Project work: You can find a useful note on conservation laws on It's learning. |

I have now posted a new version of the course note under schedule. Many mistakes have been corrected but I'm sure there are many left for you to find. Thanks to Håvard from the reference group for his help with the note. |

The oral presentation of the project will take place on the 5th of April 2011 starting from 14:00 in 1329 SBII (the room has already been reserved). We expect to finish by 17:00 or so. Those who have problems with this date should contact me immediately (and before the end of week 7). Your project should be finished by the 5th of April, even if you will get some extra days to make corrections to the report after the presentation. Please come earlier than 14:00, if you can, to set up your posters. |

Update on the voting 11 (before Easter) against 6 (after Easter). |

There will be an exercise class Wednesday February 9th at Nullrommet. We will look at the Matlab exercises from the first four problem sets. |

We voted today to decide if we will organize the presentation of the project work before or after the Easter break: the resluts are 9 votes before Easter and 4 votes after. Since not all of you were present, please let me know your opinions about it (sending an email regarding your preference or contacting one of the persons in the reference group). The decision will be taken by majority of votes. |

In the next exercise section (Wednesday february 02), we look at Problem sets 1, 2, the exam exercise on BVP, and exercises 1 and 3 form Problem set 3. We postpone the focus on Matlab exercises to a later time. |

The note of the course is now available under schedule (all chapters form 1 to 7). The note is still under construction, I will keep you posted regarding any updates. |

Exercise class has been rescheduled to Wednesdays 14:15-15:00. Note that this time only applies to the semester project. For the other exercises, please contact Geir for an appointment. (Or just send a mail with your questions if you think answers by mail will be satisfactory.) |

First class: Tuesday 11.01 at 14:15 in room S1. |

You can read the Chapter 1 of the note, see schedule, as an introduction to the first class of the course. This is background on linear algebra and I plan to solve some exercises in linear algebra. |

There will be no exercise class in the first few weeks of the semester. If you need help with the course or with the solution of the exercises, please ask for an appointment with Geir or Elena. |

- The classes 19.01, 26.01, 02.02 and 16.02 we will focus on theory exercises supervised in F3.
- There will be exercises classes in "nullrommet" 3. floor Sentralbygg 2 on the 9.02, 23.02, 09.03 (Elena's office), 16.03, 23.03, 30.03, 06.04, 13.04.
- There will be extra project supervision instead of regular lectures on Tuesday 22.03 and Friday 25.03.

If you require further help with exercises, exam sets and project work please ask Geir or Elena.

See the exercise page for more information.

## Semester project

The semester project counts for 40 % of the final mark.

## Reference group

Håvard Heitlo Holm Email: havahol (at) stud.ntnu.no

Ingvild Amaliksen Email: amalikse (at) stud.ntnu.no

## Text book and other teaching material

*Finite Difference Schemes for Partial Differential Equations*, John C. Strikwerda, SIAM, (second edition).- We will use a note written by B. Owren. You find the first chapters under schedule.

## MATLAB

Here are MATLAB files from the course and other MATLAB examples.

**Vurderingsform og fastsettelse av karakter i kurset**

- Semesteroppgaven teller 40 prosent av sluttkarakteren. Avsluttende eksamen teller 60 prosent av sluttkarakteren.
- Det er ikke obligatorisk å levere inn semesteroppgaven. Om man ikke leverer inn noen slik oppgave har man likevel adgang til eksamen. Men merk at da blir maksimalt oppnåelig resultat 60/100, dvs bokstavkarakter C.
- Man krediteres kun for semesteroppgave gjort i inneværende semester. Man får ingen kreditt for semesteroppgave innlevert i tidligere år kurset har gått.
- Totalkarakteren er den eneste offisielle karakteren i kurset. Det som legges ut av delkarakterer på disse hjemmesidene er uoffisielt, og kan vel egentlig ikke refereres til ved en eventuell klage.

**Evaluation system and marking in this course**

- The project counts for 40 % of the final mark. The final exam counts for 60 %.
- It is not compulsory to hand in the project in order to be admitted to the final exam. But note that in such case you will be able to get a final result of 60/100 maximum, that is at most the mark C.
- You get credit only for project work made during this semester.
- The total mark is the only official mark for the course. The marking of the project which will be published on these webpages is nonoffcial, and can not be referred to during a complaint.
