Compressible flows and CFL condition - A quick note about simulating hyperbolic problems |
Quasi-1D isentropic nozzle expansion - [Octave, 2018] - A couple of scripts solving the isentropic nozzle equations. Given a nozzle geometry and the conditions in the throat, they return the velocity, Mach number, density and pressure along the nozzle. |
Sod shock analytical solution - [Octave, 2019] - Analytical solution for the Sod's shock tube problem. It will work also for Matlab. For uR = 0 only. |
Finite Volume solver for Euler equations - [Octave, 2020] - The simplest ever finite-volume solver for the Euler equations of gas dynamics, in 1D. Uses HLL flux functions and explicit forward Euler integration. It works also for Matlab. |
Rates from cross-sections - [Octave, 2018] - A couple of scripts that: (1) compute rates from given cross-sections and (2) fit the modified Arrhenius law to a (chemical production) rate tabulated against the temperature. |
Tiny tutorial on SPICE - the circuit simulator - [html page, 2019] - with suuuuper simple examples! |
Equivalent Series Resistance (ESR) - [html page, 2018] - aka: "why do they put a large and a small capacitors in parallel". |
Graphics Importer - [Octave, 2016] - Simple script to extract data from images. Supports log plots. |
Paraview Colormap Generator - [Octave, 2016] - This script creates a "stepwise constant" colormap for Paraview. The link opens a page with a brief description and a nice picture. |
