Homework 4
Exercise 1:
The role of function "createSimulation" with overloading is to do :
- 2.
...
Exercise 4:
Can run the example using the command ./particles 365 1 ../init.csv planet 1 from the build folder. From C++ the gravitational constant G must be changed accordingly.
The trajectories can be viewed using Paraview, and we observe trajectories as expected. Except for Mercury.
Exercise 5 through 7:
See the file python_functions.py. Run the file from the build folder with python3 ../python_functions.py.
Note that we assume 5 integers in the filenames (e.g. step-00000.csv), i.e., not 4 as in the trajectory folder. We can easily rename multiple files using the command rename 's/step-0/step-00/g' * in order to get same naming convention.
We find that the scaling factor for Mercury's velocity is approximately 0.4.
