It seems that we both run Maple in the same way. If Maple were a drink, I would say we like it neat. The only difference I see is the natural language package which I installed for a test. I do not use it. I hope timelimit will improve for you with the library change.

@nm 

libnames are the same as in your update. I only have a Physics Update lib. Additionally a Natural language lib and a MapleSim lib.

I do not see a Physics lib (i.e. without update) if it was that what you removed from your libnames.

I also used Maple 2024.2 and Physics version 1824.

However, I am not sure if I understand correctly. Was there additionally to the Physics Update lib a Physics lib that you removed. If so, it could be the reason for discrepancies that we observed on other occasions between our two installations.

This is how the user related libs look like on my machine

You are using VariationalDifferentiation as if it was a Maple command. The output tells that Maple does not know the name

What do you intend to do with it?

@acer 

Thank you for the analysis. Indeed, I intend  to do much more with it than plotting

@Kitonum 

One thing I did not like about my trials was that they effectivley used the operator form of the plot command but showing a variable in the first argument of the plot command. Your variant is much cleaner also in functional notation

plot('r(t)',t= 0..3, size=[1000,400]);

It seems that functional notation inevitably goes hand in hand with quotation marks when using plot

Thanks!

I basically have the same setup appart of having less memory (32 Gb) and the fact that your machine is much faster. I could check for the "experiences pack" if you tell me where you did the screenshot.

60 seconds did not have an effect. Maybe you could try shorter 

I will try later during the day on a faster machine.

@TechnicalSupport 

On windows 10 with the latest physics update

@acer 

Maybe the server also needs a restart: I see here more than than 10 deleted comments.

@Carl Love 

Interesting!

Thank you

Select the output in acers answer and drag&drop it to a new input line. This will give you the Maple statement you a looking for. Note that the first argument of hypergeom contains two elements

-r^2*((1 - beta)/gamma)^n*hypergeom([n, n/(a - beta)], [(-1 - n - beta)/(-1 + beta)], -r^((3 - 3*beta)/n)*chi^2/gamma)/3;

@acer 

There is a misunderstanding in terms of numbering.

We both talk about the same best way: the one with the nested seq commands.

I have updated my first reply to you.

@acer

For the intended purpose your way (the second in sequence in this post) is the best. My attempt of using a function might be better for a color function.

The comparison of both approaches is in any case instructive.

Thank you

@janhardo 

Thank you for a commented the code variant. It's simpler than mine!

rmod is even not needed.

@acer 

A comparision of the two methods is not only interesting in terms of speed.

I have two questions:

Why should I use undefined instead of NULL?

Why is the shading not continuous? (I do not need it for stl export but for renderings in Maple it would be desirable)
