NODEMaple [v1.6.0] — released

Anthrazit — Thu, 12 Nov 2026 21:36:06 Z

I've just published a new release of NODEMaple, my open-source collection of Maple workbooks and library routines for structural design based on the Eurocodes, with a focus on timber construction (EC5).

What's new in this release:
Material, steel profile and timber fastener properties are now accessible from Grasshopper using Python.

What's inside:
Maple worksheets and library code, Grasshopper definitions, Excel sheets, supporting scripts and bitmaps — everything you need in one download.

Where to get it:
The project lives on Codeberg (https://codeberg.org/Anthrazit68/NODEMaple), with releases also mirrored to GitHub (https://github.com/Anthrazit68/NODEMaple). Just grab the release ZIP and you're set.

Feedback, bug reports and contributions are very welcome — especially from fellow structural engineers using Maple in practice.

integer solutions via isolve and rationals from el...

Focusing on the first equation, integer solutions for given B, D can be found exhaustively using the divisors of T = B^3 + D^3 and isolve. We have the factorization x^3 - y^3 = (x-y)*(x^2 + x*y + y^2), so for any pair i,j of divisors of T with i*j = T, we can get isolve to solve {i = x -y, j = x^2 + x*y + y^2}, and filter out solutions that are not positive.

For example for B = 36, D = 48, this procedure gives the two solutions {{x = 54, y = 6}, {x = 72, y = 60}}.

For rational solutions one can apply the usual elliptic curve algebra procedure using {x = B, y = -D} or one of the above solutions as a starting point.

I will add details once the Mapleprimes firewall lets me copy and paste text or upload a worksheet.

I will look for the font

@vv Actually the character is called "blackboard 1" The characters are being used in geometrical algebra boook I am studying. I live in Europe too (UK).
At least now I know whet to look for.

@Ronan It's about OS (Windows in my case)...

@Ronan It's about OS (Windows in my case) not Maple. The font containing the character must be installed in Windows. The character seems to be some Korean one. I live in Europe ... :-)
