General information
- Form of teaching: The teaching consists of a combination between lectures and projects work. Projects are made using the programming language "Python".
- Assessment:
- Project 1 Trojans and Integrator 20%
- Project 2 SPH in 1-D with shock tube 30%
- Project 3 SPH in 3-D with planet collisions 20%
- Homework 15% . Homework is expected one week after it is given out!
- Presentation on projects 15%. Presentation will be given for 15 minutes on your chosen topic and must be closely related to astrophysical simulations
- Grading scale: U-G-VG
- Course plan: in English, in Swedish
