Mathcad

I bought a student license key in November and have not been able to activate it as it says max number of licenses despite MathCAD being on express right nowThis is extremely infuriating and need some form of support to fix this.I cannot access the global support as it says my account does not have sufficient clearance and the support bot is uselessI would do an email thread but the Issue Logger only allows me to open a community thread

Hi my current workflow involves input a few variables on the first page of mathcad worksheet, then jump to the last page to see the output results after lengthy calculations. I have to tweak the inputs so that the output can meet or at least is close to certain value range. This is not efficient, so I am thinking if the worksheet can take in multiple sets (say, about 100) of input, read one set at a time, do the evaluation, then write the output result somewhere/in some file; then it will jump to the next iteration.I do not want to rewrite the input as vectors, because this will require rewrite all formulas using vectorize operators. Thank you . 

I am looking for Mathcad files that deal with synchronous electric motors (non-salient poles and salient-poles).These files should include fundamental mathematical equations for the motors and the calculation of their characteristic curves. A few years ago, I had access to this type of file, created by Mr. Roman Miksiewicz of the Silesian University of Technology (Poland).Unfortunately, the files I have do not cover synchronous motors. If you have such files, could you please provide them to me as Mathcad "xmcd" files, as I do not have Mathcad Prime?I am a retired engineer and volunteer my time helping students with their studies. Thank you in advance. Richard

I just changed my laptop. Why is it so hard to reinstall MathCAD Express? The download link in the mailbox doesn't work anymore, and when I sign up for a new trial nobody sends me any email. If you could provide me a download link I would greatly appreciate it. Thanks!

I am using Mathcad Prime Release 9.0 and Datecode9.0.0.0Hi, I have a question on: how to use a "solve" function inside a for loop or how to use it for solving variables from arrays or using the solve function inside a solve block? In the solve block, I can use Find or root functions but these methods don't give sometimes the exact solution to the equation on hand. And "solve" works the best for my case. Thank you for your help

Hello, I have a completed Mathcad sheet that makes a 3D mesh. I am requesting to please help if the Q function that generates the mesh can be simplified such that the processing time is less. My version is 10. Thank you      

Hi PTC Community,I am not sure why this programming construct will not work: apply the Nu function on a scalar & a column vector. I use Mathcad Prime 11.0.1.0. Thanks,thodij

I am using Mathcad Prime Release 11.0 and Datecode11.0.1.0Error -15: Cannot connect to license serverI installed FlexNet Admin on a virtual machine and configured it as a PTC licensing server. The license file has been configured, and all required ports have been verified as open.When launching Mathcad Prime and attempting to connect to the license server, the application reports that the license was added successfully. However, when I check the license settings, the server is not actually listed. If I attempt to add the license server manually, I receive the error:-15: Cannot connect to license serverI followed the PTC troubleshooting guide for Error -15 but was unable to resolve the issue:https://www.ptc.com/en/support/creo-admin-troubleshooter/error-code/error-15Any guidance or suggestions to help resolve this issue would be greatly appreciated. Thank you.Here are the errors that I faced-15: Cannot connect to license server.

Xmcd objects inserted into Word documents cannot be opened with Mathcad Prime.

productkey won't activate,I got my Activationkey from my school on the 09/02/2026 (it is valid for a whole year) and tried to download mathcad for several times now please help i need the programme to finish a school project

it is showing that, you have reached the maximum number of license requests available for your product type

Hello, I use Python to extract data from Mathcad Prime files, based on the previous post below. One thing I noticed is that our Python tool will crash when you have a new line in a text region. Getting rid of the new line in the text region gets rid of the crashing issue. When I go into the Mathcad .zip file with all of the XML data, I do not see any difference between two files - one with text with a new line and one  with no new line. Where would I find the new line data in the text region? I will update the Python code to catch new lines, but I dont even see where the new lines are in the text region.    Mathcad Prime 9.0 Scripting with XML Data - PTC Community

I am using Mathcad V15.  I have started playing with using controls in some of my sheets to limit certain variables to having only certain inputs.  In my one sheet, I added a list box control for a variable, and the only choices the user could select would be "B", "C", or "D".  When I finished my sheet, I set the variable to selection "C", saved and then closed.  When I reopened the sheet, the selection of "C" for the variable was cleared.  Is there a reason why the sheet did not retain the selection for the control?  Is there a setting somewhere that I can change that will allow the selection to remain?  Thank you!

Happy New Year!   This month’s challenge is inspired by recent events: the October 2025 Louvre heist in Paris France.   Using Mathcad Prime, solve any or all of the following challenges: Challenge 1 (Polygonal): find the minimum number of guards necessary to cover 100% of the following polygonal space. To be unobtrusive, the guards must be placed at vertices. The guards are inside the museum. Assume that the guards can turn their necks and bodies to see everywhere around that point that is not blocked by a wall. The guards have excellent vision and can see everything clearly between them and a wall.     Challenge 2 (Graphing): using the plotting and charting capabilities of Mathcad, depict the placement of the guards and their zones of coverage.   Challenge 3 (Orthogonal Variant): find the minimum number of guards for the following art gallery.     Challenge 4 (Graphing): Depict the placement of the guards and their zones of coverage for the orthog

Hi there ,I need to do this check that F< fy ...I get the wrong answer .. can  you help me to fix it I don't know why I can't upload the picture here it is attached      

I activate Mathcad Prime 10, using a License Key supplied by my employer (Wageningen University) where I work as lecturer, but after few days this key doesn't work anymore. When i try to use it again I receive the notification that I achieved the maximum number of licenses.The ICT supplied me other license keys, but the result is always the same: few days and I go back to the express version. I also reinstalled Mathcad Prime 10I think there is a problem with my educational account: giuseppe.olivieri@wur.nl. Can you check it?RegardsGiuseppe OlivieriWageningen UniversityThe Netherlands

I am using Mathcad Prime Release 11.0 and Datecode11.0.0.0How can we work with AI models to generate Mathcad worksheets?Is there a way to generate calculations with an AI LLM so it writes them in Mathcad format?Is there an MCP to connect Mathcad to AI models?

The attached file has two functions.  The top function work but will not allow double quotes in the second column of a text file.  The second function works to do that, and it works well enough.  Was wondering if I could improve it with a TRY... ON ERROR addition?

Hi PTC Community - I have two variable quantities (Water & Ammonia) evaluated over two different temperature ranges over which only they are each valid.I would like to plot both with a common x-axis range (-70°C to +370°C), and not be limited to either the T1 or T2 (MIN, MAX) range.See how the Ammonia (pink) plot is being limited to the MIN(T1) value of 1°C. See attached. I am using Mathcad Prime 11.0.1.0. Your tips and suggestions for a fix will be appreciated. Regards,thodij

I received the trial email, but the download link redirects to the homepage and no trial appears under My Products.Please assign the trial license to my account or provide a direct download link.Thank you.

If you now go to Mathcad's website, you'll be redirected to the Mathcad page on PTC.com. You'll also notice there are suddenly a bunch of new Mathcad pages on PTC.com that weren't there before. And you'll notice that Mathcad is a "Featured Product" and Engineering Calculations is a "Technology" on the PTC top navigation!   Yes, this is all intentional. If it seems like I've been quiet for the past several months, that's because it took a lot of work to return Mathcad back where it belongs! (And if you were wondering why new Mathcad blogs and webinars were being published to PTC.com and not mathcad.com for the past half a year, or why old Mathcad webinars are being uploaded to the YouTube channel, this is why.)   PTC.com, in terms of available technology, security, and usability, is vastly superior to what mathcad.com can offer. I hope you all see a lot of benefits to this move.   If you have any questions or found any glitches, please let me know!

I am the onsite tech for an Engineering company.  I have a user who has Mathcad Prime version 11.0.1.  The install did not give me the option to install Xmcd, MCD converter.  I read the posts that the user needs version 15.0 or higher to have those features but the user says that she does not need 15.0.  She said that is an older version and she won't be able to run her files.  How can I get this feature installed?

Hello!In my case, I would like to plot an S–N curve for fatigue life.I need the initial slope to be m = 3 or m = 5, and after the knee point, the slope should change to m = 22, specifically for the high-cycle fatigue region.On the Y-axis, a stress range up to 300 MPa is sufficient.On the X-axis, I need the range from 0 to 4 × 10⁷ cycles, and importantly, the X-axis must be in logarithmic scale.I have attached an example S–N curve below for better understanding.I noticed that there is a logarithmic scaling function available in Mathcad plots, but I am not able to apply it correctly for my specific case. BrNLAAL
