How to check if a parameter set is in SI base units

C_R — Thu, 30 Jul 2026 21:08:28 Z

For a numericial integration I want to check if all physical parameters are given in SI base units (before stripping of the units for the integration). Right now I am doing this

Parameters

(1)

H: length of rod
R: outer radius
r_sub: outer radius of heat flux
k: conductance
ρ: density
Cp: heat capacity
Q_flux: heat flux
T_amb: initial Tempearture
Nz: number of axial grid points
Nr: number of radial grid points
t_final: integration time
t_step: sampling interval for temperature fields
test_1: unit given in kilos
test_2: unit given in derived base units

(2)

α: thermal diffusivity

One way is to check whether the value of a physical parameter has not changed after simplification

(3)

(4)

I am interested in simpler ways to perform the test. The statement is quite long and not easy to understand.

Given the size of the unit package, there might be a command that I have overlooked to check whether units are in SI base units.

Have I missed test cases to make the check fool proof?

Update: A variant with split was added and attempts with functional programming

Agent Skill for Maple

OptimusMaplePrime — Wed, 29 Jul 2026 18:36:34 Z

Has anyone developed an Agent Skill for Maple compliant with the Agent Skills Specification?

I frequently use Claude Code to create and edit Maple Documents. It does fine alone, but I found adding a script to do a syntax check eliminated a lot of content errors. I also presume some instructions on how it should read the Maple documentation will improve its reliability. Before I go about writing my own Skill against the specification, I just want to check if there is already one in use within the community.

MapleV for emacs 30.2

Mac Dude — Wed, 29 Jul 2026 14:09:15 Z

I am a long-time user of Joe Riel's maplev mode in emacs. Upgraded emacs to version 30.2 and now it does not work anymore because of difficulties with something called abbrevlist. This is on MacOS. I am already on the last version of maplev.

Anyone have an idea what is going on and what to do? Somehow for me referencing a username no longer is possible (I get a blocking box with a spinner upon entering the at sign) so I can't create a notification for Joe.

TIA,

Mac Dude.

Is MapleSim and the B&R Connector included in the Student License version of Maple?

sreilly17 — Wed, 22 Jul 2026 12:07:20 Z

Pretty much what the title says. I am a student and I've worked with B&R Automation Studio, which is a SCADA software, with the physical automation components in the lab in college. Now that I'm on the summer break, it would be great to continue this learning via the B&R connector that Maple offer, to create a "digitial twin". However, there doesn't seem to be any information as to whether MapleSim is actually included in the student edition, and whether the connector is included too.

Thanks

Why does Text appear like 12 pt, with a style-set?

erik10 — Tue, 14 Jul 2026 00:49:28 Z

For many years I have used my own Style Set in Maple, mainly by adding a few extra heading styles (typically coloured headings). This has worked very well.

In Maple 2026, the default body text font has been changed to DejaVu Sans. Since the mathematical notation is still displayed in a serif math font (for obvious reasons), I feel that 12 pt DejaVu Sans appears noticeably larger than the mathematics because of its relatively large x-height. To my eyes, 11 pt gives a much more harmonious balance.

I therefore tried to change the built-in Text style from 12 pt to 11 pt.

However, I noticed something very strange.

When I open Style Management, select Text, and click Modify, the Character Style dialog already shows the font size as 11 pt (see the first screenshot). Nevertheless, when I switch to Text mode and start typing, the body text is still created as 12 pt, and the toolbar also reports a font size of 12 pt.

If I create my own custom style (for example, text11) with a font size of 11 pt, it works exactly as expected.

Is the built-in Text style intentionally overridden somewhere by the default Style Set, or is this a bug?

For comparison, I have also attached a second screenshot showing the visual difference between 12 pt and 11 pt body text. In my opinion, the 11 pt version blends much better with the mathematical notation.
