PyECHO4d

PyECHO4d

Dear Colleagues, I have created a project called pyECHO4D, which involves Python scripts for pre- and post-processing data for Code ECHO. It is publicly available on GitHub. The scripts were converted from MATLAB with the help of ChatGPT. Of course, I have corrected any errors and tested them using examples. Here’s the link to the repo:https://github.com/zagorodnov/pyECHO4D At the moment, it contains only files from the ECHO3D/src directory. These can be used instead of the MATLAB files available in the latest…

The package ECHO1D is updated to version 1.3

The package ECHO1D is updated to version 1.3. The algorithm is changed to include the impedance boundary condition (IBC). The IBC allows to simulate the normal conductivity (NSE) and the anomalous skin effect (ASE). The example N6 describes the setup. See Docs directory.

ECHO3D under Mac OS

ECHO3D under Mac OS

The Mac OS version of ECHO3D has no GUI or viewer. Hence I would start with the windows version and only after some experience to switch to the Mac OS one. There are my instructions how to use ECHO3D under Mac OS. 1. Download it from the site “echo4d.de”. It could take some time to wait before the download will start. 2. I am not registered Apple developer. Hence by the first run you have to confirm that you trust…
