@mmcdara The error message quite clearly indicates a problem with your browser. I had no trouble viewing the two PDFs with Firefox (macOS, Linux, Windows), Safari (iOS and macOS), Edge (Windows). There are no access restrictions.

Please see the very first example on the ?VectorCalculus,int help page (just plug in 1 for r).

P.S. SPAM link removed from your question.

@acer Good points, indeed. I had not noticed the first one because I had the Units package loaded (but omitted that with line from my code snippet). Everyone working with units will do so. ;-)

That minimize call is working well in Maple 2024, returning -0.3970010694 quickly. Setting _EnvExplicit is unnecessary here.

@goebeld Sorry, I have no such guide. There used to be a 3rd-party product (called Maple IDE, based on Eclipse, for coding in Maple) that came pre-configured, but it's no longer available.

For simply testing the API by running the built-in examples, I used command-line tools on a Linux system, and it worked well.

Could it be that your last equation should read

L3=HJ+h3

as opposed to

HJ=L3+h3

Just a guess from the pattern for the other two equations...

With that adjustment, fsolve succeeds.

@Preben Alsholm That feature was introduced in Maple 2018.

@Ronan That‘s part of the MapleSim 2024.1 installer. For other customers, the Maple update will be available soon. By the way, I ran the worksheet on a Mac with 2024.1 (and no Physics updates yet), and could not reproduce the KCL error either.

@nm No worries, we all make typos from time to time. Yes, I think it's useful to delete this thread, because the GIGO principle would prevent any useful processing (in the sense of a bug report), I guess.

There is a multiplication symbol missing in your input ode... After fixing that, dsolve will return two elementary solutions, and map(odetest,[sol],ode) will return [0,0].

The import process runs into an error message:

Modelica_LinearSystems2: cannot resolve `classDirectory` in modification in package `Modelica_LinearSystems2`; there is no `classDirectory` visible

(in MapleSim:-GUI:-BuildLibrary) no classes found for Modelica_LinearSystems2
(in MapleSim:-GUI:-BuildLibrary) no classes found for Modelica_LinearSystems2

Failed to create the library

So I'm afraid it will require some edits to the library and/or adjustments in MapleSim.

Not sure what's going on here, but at least in Maple Flow 2024, it works if I omit the unevaluation quotes.

In version 2023, I had to use the keyboard shortcut (Ctrl-Shift-u) instead to insert a unit placeholder. Worksheet attached: unit-entry-2023.flow

That also works in 2024.

Could you check if security tools may be blocking that operation? See our FAQ page, please.

@C_R Yes, it's a known issue that some lines are simply too thin. Rescaling / zooming then helps indeed.

@nm I guess it's by design. Infinite scroll works well in my preferred browser (Firefox), so I would not see any reason to disable it.
