# Comparing with the analytical potential
|
|
|
|
Plot a log-log plot of rho(r):
|
|
- the discrete solution has poissonian error: 1/sqrt(N) where N is the number of particles in the bins
|
|
|
|
=> ensure the discretization is consistent
|
|
|
|
|
|
# Comparing forces
|
|
- Use newtons law by considering only the inner shells:
|
|
F_i = GM(R_i)/R_i^2
|
|
|
|
|
|
=> this should all be done with the .ascii file (All particles, not yet meshed)
|
|
|
|
|
|
|

|
## Task2
|
|
a) start with only the monopole and compare with the direct summation
|
|
only then build the tree code
