I have Maple 2021 and Mapleflow 2021 installed. The Maple 2021 is working fine. However, MapleFlow gives the error as follows. ERROR: Flow does not evaluate to a module. My system OS is Windows 10 updates till April 2022

I get this error when typing a sigma symbol with some subscripts.

Is there anyway to get rid of it?

If mapleflow doesn't allow typing in this way, how can I type it in an unexcutable Math format like document mode in Maple?

Is it possible to read and/or convert Mapleflow sheets to Maple?

Hi, just some ideas for improvement!

- since MapleFlow uses Maple as its engine, more integration of MapleFlow and Maple would be nice. Some commands that work very well in Maple not always work the same in MapleFlow. For example, BodePlot plots magnitude and phase in Maple but plots only magnitude in MapleFlow

- a better Help documentation would also help. ?command/function works in Maple but not in MapleFlow. It's a bit anoying to have to open Maple just to get help documentation

- a lot of palettes are not enabled in MapleFlow. Again, it is a little anoying to have to open Maple to get some of the palettes copied and pasted into MapleFlow

Is it possible to open or import, and execute Maple Flow documents in Maple 2021?

We have just issued a critical fix to Maple, MapleSim, and Maple Flow running on macOS.

We have heard from some users who were experiencing serious problems with doubled characters while using Maplesoft products on macOS, including these reports on MaplePrimes. Further investigation determined that these problems appear specifically on macOS 11 and macOS 12.  I am happy to report that we have now corrected the problem, and a patch is available. 

Anyone who uses macOS 11 or macOS 12 should install this update immediately. We also strongly recommend that all macOS users install this update, to avoid problems that may be triggered by future updates to your operating system.

To obtain this update:

• If you have Maple only, follow the instructions on the Maple 2021.2.1 update page.
• If you have MapleSim, visit the MapleSim 2021.2.1 update page.
• If you have Maple Flow, follow the instructions for Maple Flow 2021.2.1.

For those who have experienced problems, we apologize for the inconvenience and thank you for your patience while we worked to find a solution.

I am evaluating Maple Flow 20212.2 on a Macbook Air M1 running MacOs Monterey 12.2.

Unfortunately this is being severly hampered because for every keystroke Maple Flow is entering 

that Character twice.  Disabling keyboard autorepeat and restarting Mac or Maple Flow makes no difference.

Anyone got a solution for this?

Hi,

does anyone has any idea on how the number of digits displayed and the accuracy of calculations in MapleFlow works?

It looks like it is nothing like it is in Maple.

For example:

Digits:=10

interface(displayprecision)=3

1.02¹⁰=1.219

interface(displayprecision=10)

1.02¹⁰=1.219

Digits:=15

interface(displayprecision=10)

1.02¹⁰=1.219

Best regards,

Hi.  I have not been able to find the individual cost of Maple Flow.  How much does it cost?  (in CDN)  Is it inlcuded in Maple?

Can Maple Flow be installed on Linux?  If not, will a Linux version be released on the future?

Regards

Hi,

I have a MapleFlow program that perform some symbolic calculations. To test the program, I assign a numerical value to a variable, say a:=1.6, in the middle of the program. I would like to clear the variable and continuing the program development using symbolic calculations. I've tried unassigning and restart but nome worked.

Any ideas?

Hi,

I tried a simple expressioin using imaginary numbers in MapleFlow,

a:=1 + 2*i

but got the following error:

¨'mn' is not numeric"

does anyone know what is happening?

thanks very much.

hi,

I looked at the file mapleflowrc and saw that it lists several palettes that are not visible in the workshheet dock.

Does anyone know if these palettes are available in mapleflow? And if so, how to make them visible in the worksheet dock?

thanks very much in advance.

Hi, I'm just trying to use assign, like in Maple,

s := solve({x + y = 1, 2*x + y = 3}, {x, y});

                      s := {x = 2, y = -1}

assign(s);
x, y;
                             2, -1

in MapleFlow, but it doesn't work!

Any ideas?

Thanks very much in advance

Is Maple Flow available as individual licence similar to Maple? 

We’ve been busy! We have just released the 2021.2 updates for Maple, Maple Flow, and MapleSim. Here’s a quick overview. These updates are freely available to all customers who have the 2021 version of these products.

Maple

The Maple update includes a variety of corrections and improvements to the math engine and interface. It is available through Tools>Check for Updates in Maple, and is also available from the Maple 2021 download page, where you can also find more details.

In particular, this update includes fixes to the bug in the combine command when working with double summations, and the problems when performing context menu operations on values with units while in Document mode, both of which were reported on MaplePrimes. As always, we appreciate the feedback!

Maple Flow

The Maple Flow 2021.2 update offers a richer range of formatting features for creating professional-looking engineering documents, which have been requested by customers. Highlights include sections, controlling the display of commands, annotating images, and disabling automatic evaluation while making a series of changes.  This update is available from the Maple Flow 2021.2 download page, which also contains more details.

MapleSim

Lots of good stuff here that makes it easier to build and analyze models, including productivity features that speed up the creation of models that use hydraulics, support for the latest CAD file formats in the MapleSim CAD toolbox, the ability to model drift conditions with the MapleSim Tire Library, tools for simulating 3-D winding effects with the MapleSim Ropes and Pulleys Library, and a new MapleSim Web Handling Library add-on (which, I am sad to say, has nothing to do with Spiderman). See What’s New in MapleSim for details, and the MapleSim 2021.2 download page for instruction on how to obtain your update.
