hydes 0.0.5

Hydrodinamical equation solver

HyDES

Concept

HydroDinamical Equation Solver Code to numerically solve the hydrodynamical equations in 2 dimensions in a regular rectangular mesh. The code performs a first order staggered Lax-Friedrich scheme in time and a central first order derivative in space. There are several initial conditions to test and a some boundary conditions, like 0 derivative in the boundaries or periodic ones. The code is impleted originaly in IDL in may 2019 and it was transcripted to python in december 2021.

Installation

To install the library just pip install it with:

pip install hydes

Getting started

To start simulating your models just load the library, load the parameters (template loaded with load_sample_params()) compute the desired initial conditions with a perturbation and simulate the evolution of the sistem like:

import hydes as hd

params = hd.load_sample_params()
pert, pert_vx, pert_vy = hd.sample_perturbation()

hd.run_sim(params, pert, pert_vx, pert_vy)

if you also want to have a movie of the saved plots you can do:

import hydes as hd
from animation import animation

params = hd.load_sample_params()
pert, pert_vx, pert_vy = hd.sample_perturbation()

reults_path = hd.run_sim(params, pert, pert_vx, pert_vy)
frames = os.path.join(os.path.join(reults_path, 'plots'), '*')
animation(frames=frames, path_out=reults_path)
