- 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
