Mathcad

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.

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  

I've changed laptop recently and don't have MathCAD anymore. So, I requested a few times through website's online form, but no email received so far. Could you please explain where the problem is?

Dear Sir/Madam,I need to perform calculations for my studies and have set up a Windows 10 computer and installed my student version of Mathcad 15. Unfortunately, Mathcad 15 cannot be activated because the license server is no longer available.Can you help me activate Mathcad 15?Thank you in advance.Best regards, Dieter

I have a code that is looking through the matrix and selects creepage based on my input parameters (PD, MG and working voltage WV). It works great....in picture 1. picture 1 Now, I want to add a linear interpolation between 2 values of the voltage. I made a variable "a" doing linear interpolation and tested it works as expected, which it do. Column variable for searching in matrix is hardcoded at the beginning for test. Now, since it work, code A (linear interpolation of the creepage) replace code B (that is using only search method w/o interpolation) in the original code. That is the only change in original code. Code A is tested it works, gives values I need but after A replaces B function that is calling creepage(WV,PD,MG) is complaining "These units are not compatible". What am I missing? I dont see any problem there. thanks Running on Mathcad Prime 11.0.1.0

I was trying to convert a mathcad 15 file to mathcad prime 9, but I get an error in solving for this variable I placed all my guess values and constraints but it still does not work.
