I need to compute complicated numerical integral, and my Maple integration does not produce very stable results. Is the a way to do that on line? 

In Maple 2025.1, why don't all the hotkeys show up when I press the Alt key?

Maple 2025.0 is OK,but update to 2025.1 all the hotkeys don't show up when I press the Alt key.Why?

My name is William Cheung.  I am a Snapdragon X AIPC product manager.  I am reaching out to inquire about the current and future compatibility of Maple on Snapdragon X Windows PCs, which run on ARM64 architecture. With the growing adoption of ARM-based systems in enterprise and academic environments—especially those powered by Qualcomm’s Snapdragon X Elite platform—we are evaluating software solutions that can run efficiently on these devices.

Could you please confirm:

  1. Whether Maple, as a commercial product, currently supports Windows on ARM (either natively or via emulation)?
  2. If not, is there a roadmap or timeline for ARM-native support?
  3. Are there any known performance or compatibility issues when running Maple on Snapdragon X PCs using Microsoft’s Prism emulation?

Note that I have successfully installed and run Maple 2025 with sample worksheet files on my Snapdragon X Windows PC.

Thank you for your time and assistance. I look forward to your response.

Hello, I am struggling with a Maple Flow document that has gotten a too large to manage - maybe around 100 printed pages of relatively straightforward calculations, basic plots, etc. - nothing exotic or what should be computationally intensive.  The worksheet takes a long time to load, if it loads at all, is prone to freezing and requires force quitting of the OpenJDK Platform binary when this happens, and oftentimes generates a kernal connection error:

So, in short, lots of issues that make usability a challenge. The document is easily broken into smaller sections, which I would prefer to do anyway. I have attempted to use the RunWorksheet command and can more or less get it to work for very simple cases:

However, the output is not ideal in that it includes the variable string. This command also doesn't appear to pass custom-defined units. The other issue is that when I test this same syntax on a fully-developed, formatted, etc., Maple Flow worksheet, I get invalid input warnings and can never get any values returned.

Ideally, what I would like to do is call a variable defined in one Maple Flow worksheet and have it be immediately usable in another Maple Flow document, or at least usable with some minimal processing. If anybody has any ideas, I would appreciate it.

Thanks

Hello, I am trying to get the Maple Flow add-in for Excel working and am following the step-by-step directions in Chapter 7.3 of the Maple Flow manual. My computer meets the requirements listed in Chapter 7.2.

After selecting the WMIMPLEX64.xla file as directed in the procedure, I get the following error in Excel:

The Excel toolbar also does not show the same six icons in the add-in toolbar that are shown in the Maple Flow manual (see the manual excerpt below); it appears that the missing icon is the key icon that would initiate the Maple Flow worksheet wizard.

If anybody has been able to get this to work or has suggestions to resolve these errors, I would appreciate any advice.

Thanks

Excerpt from the Maple Flow manual:

Hello Maple Community,

I'm working on solving a PDE system for fluid flow in an L-shaped cavity (similar to previous work on H-shaped and square domains ) recently asked by some one here. I've implemented the governing equations in Maple but need help generating contour plots.

I'm attaching:
1. My Maple worksheet l_shape_cavity.mw
2. A PDF with the problem description and equations L_shape_cavity_work.pdf

The main issues I'm facing are:
- Setting up proper boundary conditions for the L-shaped domain
- Generating contour plots for velocity and pressure fields
- Ensuring the solution converges properly

Could you please help me with:
1. Correct implementation of the L-shaped domain geometry
2. Generating proper contour plots
3. Any suggestions for improving the numerical solution

Thank you for your assistance!

Is there a way to use alternative plotting packages in Maple such as open source options: Plotly or Matplotlib?

https://plotly.com/python/

https://matplotlib.org/

I've been using the $include statement when using code written in Visual Basic Editor for packages quite extensively, and this works very nice.

Would it be possible to outsource code to external files for code not in packages / libraries as well? If yes, how would this be done?

Probably an odd question, but please bear with me.

Mechanical design guy, previous Mathcad user. Liking Mapleflow alot. My issue is maple flow does not see any subfolders within the PDM "vault". The vault is designed to act with, and just like File Explorer. So I can paste mapleflow files into a subfolder within the vault, I can double click and open the file up. But when you "save as" the file, Mapleflow only sees the root directy. No other folder structure with the vault. So it makes it impossible to use the vaults functionality out side of manually copying and pasting files after the fact to where you want them. Note that he vault is desgned to use any file type. It's the Mapleflow application that's can't seem to see subfolders inside the "Vaults" root directory. Note that I've never see this with any other file type or application if many years of PDM use.

I am on the EMP plan so I'd sure be interested to have someone look at this?

Thanks for any insight!

With the new ribbon interface (and startup-page disabled) I need to open a new worksheet to make opening files by the recent document menu work.

Can someone reproduce this?

I have a Pascal program. I want to use a Maple program inside the Pascal program when calling it each time. I dont know how to interact Maple with Pascal. For this, could you give me over a small program? Yours Sincerely

How Maple 2023 displays new results with old results together

I use the tab key to control the formatting of lists. 

On my computer the tab key spacing under Maple 2025 is a little more than one inch which is too much. I have been through the Maple Help and cannot find how to change the tab key spacing.

Any help will be greatly appreciated.

Hello everyone,

I am working on reproducing Fig. 12 (Isotherms) and Fig. 13 (Streamlines) from the attached paper, cacity_paper_work.pdf which deals with natural convection of GO–MgO/silicone oil hybrid nanofluid inside square and H-shaped cavities under a periodic magnetic field.

Equations (9–11) in the paper describe the steady-state 2D flow and heat transfer in terms of u(x,y), v(x,y), and θ(x,y). I have already set up the full PDE system, parameters, and boundary conditions (BCs) in Maple.

Now, iusing pdsolve(..., numeric, method=fd), 

Solve these equations for both square and H-shaped cavities using the given ICs and BCs, and

Generate Isotherm and Streamline plots (similar to Figs. 12 and 13 in the paper).

I have attached:

The PDF (showing equations and figures), and

My Maple worksheet containing the PDE definitions and parameters.

I would really appreciate guidance on:

Whether dsolve can be used effectively for this PDE system,

How to define the BCs correctly for the H-shaped cavity (especially the partially heated wall, θ=1 for 0.4 < y < 0.6), and

How to extract and plot the temperature (θ) and streamfunction (ψ) fields similar to the paper’s plots.

Hello,

I have full access on .../.../version.txt but Maple tells me I have no write access...

Sorry for the previous post, thank you.

If I try with the install command I get the same error.

Kind regards to all

Jean-Michel
