Backupy: Backup files from local machine to NAS and cloud using backupy and python

The concept is:

Backup is important. There are many backup tools in the world. There are also a backup manager tool written in python. This page presents an example of runnning backupy.

TarManager: combine many pickle files into some tar files using Python

The concept is:

This page shows how to combine many pickle files into some tar, tar.gz, or tar.xz using Python. In some simulations, we generate thousands and millions of output files for varying some parameters and some values for each parameters. The problem of such huge number of small files is the difficulty to handle on making backup to NAS, external HDD, and cloud storage services.

Solve and animate single pendulum using scipy.odeint and matplotlib.animation.ArtistAnimation

The result is:

This page shows the example of the scipy.odeint function with solving the motion of the single pendulum. The result is converted to the animation using matplotlib.animation.ArtistAnimation.

Create animation of plt.contourf for visualize air flow past three cylinders using Python Matplotlib.pyplot and Matplotlib.animation.ArtistAnimation

The result is:

This page shows my exercise to visualize air flow past three cylinders.
The flow is calculated by commercial finite elemental method software i.e. COMSOL Multiphysics.
In this code, matplotlib.animation.ArtistAnimation function is used.

The result is:

This page shows how to draw vector field (electric field lines) using plotly. The figure is converted from matplotlib.pyplot.

Draw continuous electric field lines with sliced potential plane in 3D using Python Plotly

The result (static image) is:

Draw electric field lines with changing line color according to the electric potential

The results are:

This page shows how to draw electric force lines around point charges.
The colors of the electric force lines vary according to the electric potential in the point.
