Soft Potato wiki

Open source electrochemistry simulator.

It simulates cyclic voltammograms and chronoamperograms for planar diffusion assuming Butler-Volmer kinetics. Make sure to use the slide bar at the bottom! For more information visit https://softpotato.xyz.

Binaries

There are Windows 8.1 and Ubuntu 20.10 binaries in the releases page. Make sure to download the latest release available for your system.

Usage

For regular use, download the binary for your system. If you want to tinker with the code, then download the repository. From a terminal and within the Soft Potato directory, run:

python3 SoftPotato.py

Requirements

It requires:

• Python 3+
• PyQt5
• Numpy
• Matplotlib
• PyQTGraph

pip3 install numpy
pip3 install matplotlib
pip3 install pyqt5
pip3 install pyqtgraph

Optional for compiling with cython, see below

• Cython

pip3 install Cython

Tested with:

• Linux (PopOs/Ubuntu 20.10/Manjaro)
• Windows 8.1
• MacOS Catalina

Compiling with Cython

The code can be made around 30% faster by cythonizing the main sp.py module. This will particularly help speed up the calculation of finite-differences. To compile to code install first Cython and then run the command

python3 setup.py build_ext --inplace
