# Lines should be structured as 'PROPERTYNAME VALUE' (i.e. separated by 1 space)

# Number of particles to create at program start.
n_part 101

# The mass to use for all of the particles, in kg
mass 0.04

# Pressure calculation mode. 0: Isothermal, 1: Adiabatic
pressure_calc 1

# Boundary size -- as measured from either side of the origin (so the total width of the space will 
# be twice this value)
limit 2

# The initial velocity to give to particles when setting up the calculation. Ignored if adiabatic
# pressure calculation is enabled; 
v_0 1

# Coefficient to use in h-density rootfinding relation (see Price 2012 eq. 10, Price 2018 eq. 6)
# The number of neighbours for each particle is approximately 2 * kernel radius (2.5) * this value
h_factor 2

# The initial timestep to use for the simulation
