Hi,Another Odesolve problem with an error I cannot identify. Google AI says its a syntax problem but I am damned if I can see it.Any assuistance would be appreciated.Regards, Ross

PrimeConnect C++ -> Prime -> C++PrimeConnect is a pair of C++ solutions/projects.One writes a *.mcdx Prime output file fully described by C++ syntax that encapsulates the mathematics of a Prime Worksheet.Two reads a *.mcdx Prime input file where all evaluation regions of a Prime Worksheet can be assigned to C++ variables in one line each.They both work on the underlying feature of *.mcdx files that are a collection of zipped XML files.  In the case of Prime text regions zipped up zipped files of text.The underlying XML text manipulations are handled invisibly by PrimeConnect. User of C++ can concentrate on the mathematics when writing a *.mcdx file.  User can concentrate on what are all the evaluation regions in a Prime worksheet are and assign them to C++ variables.Writes Prime v10 files, Reads Prime v9, v10, and v11 files without varying C++ code just point the C++ to a *.mcdx file.Both Microsoft Visual Studio 2022 C++, and Embarcadero RAD Studio 12 projects are available.  The

About Mathcad 14. I have just installed it to a new PC with Windows X11. When I try to run it, it asks me to run the license assistant. I do it, I get a web page asking to create a new account (although I already have one), so I create a new account, then nothing. Thanks for helping me. Regards, Michel Bonnardeau

Hi there, I don’t know why it shows this error here . I used the same function in another sheet and it is working Regards,Yusra

Hello! I have been trying to get the free version of Mathcad, but I run into a problem. I had the free 30-day trial on my previous laptop, and now Im looking for the free, express version. I downloaded from the Download .NET 8.0 page the .NET Desktop Runtime 8.0.28 and restarted my laptop, but when I press Download again, it takes me to the same page with .NET again. 

Hello! I ha previously downloaded the mathcad trial, then used the free, limited version. I have since then changed my laptop and am trying to download it again on my new one. I filled out the form for the trial/free version, but I have not received any email back (this was a few days ago). I also tried to download the program from the "download" shortcut, but after I restart my laptop and press download again, it keeps taking me back to the same page with the downloading links. I tried .NET Desktop Runtime 8.0.28 and .NET Runtime 8.0.28, both the x64.

Reference topicThere does seem to be a bug with Polyroots. I get the same error with the Quicksheet and a manually entered matrix of coefficients.If anyone can advise how to fix this issue  your advice would be appreciated. Ross 

A PTC Mathcad Prime XML Writer in C++File created with PrimeWriter v1.1 Alpha, an Embracadero RAD Studio 12 C++ Builder program. Program creates a rudimentary worksheet as a starting point.  It is intended for further enhancement to create more elaborate worksheetsStarted with a simple request of ChatGPT"create a PTC Mathcad Prime file that creates variables a and b of 3 and 5 respectively and adds them together for variable c."This started a week long Monday to Sunday, long hours each day focused chat with chatGPT and has produced a simple programmable worksheet generator in C++. It has some functions already defined; operators +,-,/,* sqrt, sin, cos, tan, exp, pow, nthroot, max, min, atan2, lsolve, concat, det, trace, rank, eigenvals, augment, and submatrix. Adding a new Prime function type only takes two lines of code. So more will be added over time.  Greek symbols can be used.It is intended as a quick visual report writing method for my C++ FEM work.The new advantage is C++ progra

 I recently started using Mathcad Prime 12 for structural engineering / Eurocode calculations and I noticed something frustrating regarding the unit system.Mathcad correctly understands that: kg/s² = N/m. However when working with line loads (common in structural engineering), Prime often displays results as “kg/s²” instead of the expected engineering SI unit: N/m or kN/m.The strange part is that under “Insert Derived Units → Force per Length” there are several imperial units available: kpi, klf, plf. but there is NO SI alternative such as N/m or kN/m.This creates a awkward workflow in SI-based calculations, especially for Eurocode and structural design where line loads are constantly used.Currently the only workaround that i found seems to be manually dividing by (kN/m) , creating display variables or manually writing the unit as text. This partly defeats the purpose of the otherwise very capable engineering unit system.Questions:Is there any hidden way to add custom SI derived units

Hello All, The following symbolic evaluation used to calculate without any issues in mathcad 15. It does not evaluate in Mathcad Prime 11.0.1.0. i have attached the sheet,Regards,Sam   

Hi all,Last week we released PTC Mathcad Prime 12.0.0.0. We’ll be sharing more detail on www.ptc.com soon. A handful of users reported an issue with the release.Currently, PTC Mathcad Prime 12.0.0.0 will not run if it’s installed on a system where the system language is set to one other than one of the ten languages officially supported by Mathcad (US English, French, German, Italian, Spanish, Japanese, Korean, Russian, Simplified Chinese, and Traditional Chinese). If you run Mathcad Prime 12.0.0.0 on a system using one of those supported languages, there’s no problem. If you can change your system language to one of those supported languages, Mathcad Prime 12.0.0.0 will run fine. But if you need to run Mathcad Prime 12.0.0.0 on a system language not officially supported by Mathcad, you should remain on PTC Mathcad Prime 11.0.1.0 until this is resolved.We’ve been working closely with Microsoft on this issue and have identified a fix. We’re currently in the process of building and testi

I was having trouble to activate license, so I ask for that and instead of issuing license for my free trial PTC site offer me free Re-download 30 days trial which I accepted. The real problem is that I have never received e-mail to download that. I check my junk mail also and it's not there either. Please look it up to this and send me an e-mail with re-download link as I also try to re-download using old email for no use.

This month’s challenge is inspired by the greatest rock band of all time: Rush! Specifically, it is in honor of the 50th anniversary of their concept album 2112, which gave us the Starman logo. Here you can see the logo along with geometry in Creo pertaining to the challenge:Starman Star Challenge depicted in Creo ParametricNote that the Starman logo is not a pentagram, and Rush is not devil-worshipping music (as many of our parents thought). Drummer and lyricist Neil Peart (RIP) was really into Ayn Rand (which is arguably worse). The logo represents a naked man, armed only with his intellect, resisting the collectivism of the Solar Federation. Listen to the album. It’s awesome.Here is the challenge: start with a circle of radius 1. Inscribe a regular pentagon. Connect the vertices to form a star.Challenge 1: Measure the area of (1) the star, (2) the pentagon inside of the star, and (3) the tips of the star (the star minus the interior pentagon).Challenge 2: Write functions for these a

I re-downloaded Mathcad prime 12 to have it working properly but for some reason its not installing UI and because of that my its not working right

In the days before MATHCAD Prime… It was possible to annotate your analysis images with “Arrow Attached Text”.  It is no longer present.  One must annotate an image in MS Powerpoint before adding image to Mathcad Prime 11.    It makes tasks much more work going between other apps for graphics.  I add alot of “fabrication” pictures to my “Material Review” packages as I structurally review” in process fabrication opportunities.   Please consider restoring and even enhancing this former ability.    Thank you.

Good morning, Community,Please I need your help, I have converted some Excel workbook into Mathcad Prime worksheet, my problem is that the AI created the file but I cannot open the file in Mathcad Prime 11. Please see attached files for your attention.Thank you

I’ve been revisiting Mathcad after some time away, and I had a question about functionality that used to exist in older versions.Back when I was using Mathcad 15, I remember being able to plot vector fields (for example, visualizing a 2D vector function with arrows over a grid) fairly directly using the built-in plotting tools.Now that PTC Mathcad Prime has been around for a while and has gone through multiple updates, I’m wondering:Does the current version of Mathcad Prime support vector field plotting natively? If not, is there any recommended or standard workaround within Mathcad Prime (without exporting to other tools)? Has this feature been intentionally removed, or is it something planned for future releases?I’m especially interested in workflows comparable to what was possible in Mathcad 15, where defining a vector-valued function and visualizing it didn’t require too much manual construction.Would appreciate any insights from those who’ve worked with both versions

I can’t figure out how to adjust the scale of the y-axis.  Is this possible? (see screen capture)
