This is my home in the virtual world, where I write
about things that I want to share. The freely available software that
I've written as well as some of the photographs I've taken over the
years can also be found here. Please use the navigation links on the

At work, we recently bought an EBI 40 TC-01 6-channel temperature logger.
It saves data in a file with the ed3 extension.
It comes with a ms-windows program to show the data and export to CSV and ms-excel.
However, I want to be able to use the data on my FreeBSD workstation.
So I have to figure out the data format of the ed3 files.
To build an epub with sphinx, we need two directories, a source and an
The source directory should contain at least two files; conf.py
containing the settings for the epub conversion, and index.rst containing
the main text.
This is the second part in a series how to analyse sandwich structures with
FEA. The first part is here.
If you haven’t done so, you should probably read that first.
In that part we built and analyzed a sandwich where the core and skins shared
We saw how that leads to incorrect stress distribution images because of nodal
In this article, we’re going to fix that by using *TIE constraints.
This is the first part of a series of articles where I hope to show how to
analyze deflection and stress in structures using the free CalculiX software. I’m using
The focus will be on sandwich structures because that is the area in which I’m
Compared to parts consisting out of a single material this is a bit more tricky
as we will see in this article.
The main reason for using finite element analysis (“FEA”) in general is that
it allows for complete analysis of problems where no integral solution exists.
Additionally, some of the assumptions used in Euler–Bernoulli beam theory for
analyzing deformation and stresses in beams and plates do not hold for sandwiches.
