My role is to help customers better exploit our tools. I’ve worked in selling, supporting and marketing maths and simulation software for all my professional career.

I’m fascinated by the full breadth and range of application of Maple. From financial mathematics and engineering to probability and calculus, I’m always impressed by what our users do with our tools.

However much I strenuously deny it, I’m a geek at heart. My first encounter with Maple was as an undergraduate when I used it to symbolically solve the differential equations that described the heat transfer in a series of stirred tanks. My colleagues brute-forced the problem with a numerical solution in Fortran (but they got the marks because that was the point of the course). I’ve since dramatized the process in a worksheet, and never fail to bore people with the story behind it.

I was born, raised and spent my formative years in England’s second city, Birmingham. I graduated with a degree in Chemical Engineering from The University of Nottingham, and after completing a PhD in Fluid Dynamics at Herriot-Watt University in Edinburgh, I started working for Adept Scientific – Maplesoft’s partner in the UK.

This isn't a bug.

Maple Flow offers "units balancing" to make a result dimensionsally consistent. If a result is in J (energy), you can ask Maple Flow to rescale it to any consistent compound unit that contains m. Flow does some dimensional analysis, and automatically includes a unit correction factor of N (so the complete unit is N*m)

Maple doesn't offer automatic units balancing. You have to specifically ask Maple to rescale J to N*m.

Claus, could you provide more detail please? I can use both area and speed units in 2024.2 (entered via the Units palette, and manually via the units placeholder)

Claus, we've just updated Flow 2024.2.

In Flow, could you go to "Tools>Check for Updates" and install the latest version. I anticipate this will fix the issues you describe above.

@C_R Customer Service can still provide the previous version. But we're hoping to release an update to fix these bugs sooner rather than later.

Hi Claus

We can reproduce this bug if numeric formating is applied to an expression sequence or list. Please bear with us as we investigate a possible fix.

While we investigate, can you remove any numeric formating from your results (either local or global)? Does that work for you?

ifactors(3032) works fine for me with no crashing

Could you send an email to tech support (https://www.maplesoft.com/contact/webforms/support.aspx) with your build number (from the Help>About menu) and OS describing these issues?

Could you supply a specific example?

As far as I see, fsolve in Maple Flow 2024.2 returns all the roots of a polynomial:

@WhiteNoise We've thought about bringing phasors into Maple as well, but there are no firm plans. But the more people that want this, the more likely it is to happen.

@Christopher2222 We're more likely to link to a third party drawing tool than develop our own "parameterizable" drawing feature (which itself is low down on our list of priorities - at this point, I don't see a significant demand)

@charlie_fcl I'll take your feedback on board. Generally, I'm not keen on cluttering the Flow interface with little-used menu items and palettes. But if we get more requests, then I'll do my best to make everyone happy

@nick_whiston Not yet, but I'll look at converting worksheet bookmarks to in-PDF hyperlinks for the next release

I think you'll need to send the worksheet into tech support. By the way, some of those units (such as the unit in F:= 1360lbf) look like they haven't been entered into a units placeholder (they should be bold grey on input)

@shoeless I can open Flow 2022 worksheets in Flow 2023, and vice versa.

Of course, newer versions may have commands and features that are unsupported in older versions

@tim_finks By a "user-defined field", do you mean a button that inserts some user-specified boilerplate text into a header/footer?

@charlie_fcl Maple Flow 2023 is available for Mac and Windows only. We have no current plans for a Linux version.
