shocktubecalc 0.11

Simple shock tube calculator

Description

This module calculates analytical solutions for a Sod shock tube problem.

A more detailed description can be found here.

Usage

from shocktubecalc import sod

# left_state and right_state set p, rho and u
# geometry sets left boundary on 0., right boundary on 1
# and initial position of the shock xi on 0.5
# t is the time evolution for which positions and states in tube should be calculated
# gamma denotes specific heat
# npts is number of points to be calculated for rarefaction wave
# Note that gamma and npts are default parameters (1.4 and 500) in solve function.

positions, regions, values = sod.solve(left_state=(1, 1, 0), right_state=(0.1, 0.125, 0.),
                                       geometry=(0., 1., 0.5), t=0.2, gamma=1.4, npts=500)
