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.

eBook help video?

Ronan — Tue, 07 Jul 2026 12:01:16 Z

Are there any demonstration help videos on creating an eBook? Currently I am struggling with the pages Having a laid out example would really help.

I would like to do an eBook version of my help pages to send to some people. Hopefully I can use the current help worksheets. The are formatted based on the Maple help structure.

My currrent structure in the help section is:

Rational Trigonometry

(about 40 help topics)

RTProjective

(about 20 help topics)

UHG

(about 20 help topics)

Edit:- I have made a small step of progress using the " Assistant eBook template" but I am getting this error on build. I don't know how to find the cause of the error.

Missing operation (multiplication) in 2D-Math

C_R — Sat, 27 Jun 2026 11:34:01 Z

In 2-D Math input:
In a product of more than two factors space is not allways sufficient to delimite factors when one of the factors is of type numeric.

Just for my interest: Is there a reason or a rule for that?

How to get consistent output from dsolve for system of ode's?

nm — Mon, 22 Jun 2026 06:41:21 Z

Consider these two output, both for solving system of 2 first order different equations.

Why is the first result is put in a list, then each solution is in a set inside the list, while the second one is just a set of the two solutions?

My guess is that because the first system is non-linear. Is this why?

This makes it little harder to parse the result later on, as it can change each time.

Is there a way to get same output for the first example as in the second example?

Mapkle 2026.1

ode:=diff(x(t),t) = x(t)^2, diff(y(t),t) = exp(t);
sol:=dsolve([ode],[x(t),y(t)])

ode:=diff(x(t),t) = x(t), diff(y(t),t) = t;
sol:=dsolve([ode],[x(t),y(t)])

ps. the ode's are not even coupled in these example. So each can be solved on its own if needed.

And if there is one ode with multiple solutions, now dsolve returns expression sequence. No set, no list.

ode:=2*x*diff(y(x),x)*diff(diff(y(x),x),x) = -1+diff(y(x),x)^2; 
dsolve(ode,y(x));

This whole thing is a mess.

There should be one consistent way to return solutions for all cases.

Regadless if it is one ode with one solution, or one ode with mutliple solutions, or coupled systems of odes, linear or not and so on.

The output should be the same form in all cases. A list of lists or list of sets or whatever it is decided on.

But it should not change.
