Mathcad

My employer purchased mathcad for 3 of us, however despite IT saying mathcad is installed, it is only the trial version. I need to get the product key/code so I can utilize the license we paid for. To date, I have never been able to use the purchased version of mathcad and it was purchased about 3 months ago. please assist.

I cannot print to PDF when text contains Calibri font type. As soon as I change the font type to something else, such as Arial, the file will print to PDF without issue. I and several associates are encountering the exact same issue. We are using MathCAD Prime 12.0.0.1. Is this a known issue? Will it be fixed in a future update?

Hello!We have 2 users with 2 different computers reporting the same issue with their prime files.I don’t know if it has something to do with the latest august Windows 11 Cumulative update (KB5121003)?The issue started happening yesterday after the users updated their Windows 11.When we try to Save as PDF or use the Print function we get the same errors. And we have tried several PDF printers. It only creates a .PDF file with 0kb in size. I uploaded 2 files that we are experiencing this issue with.

Was wondering if there is a way to mod or get mathcad to add geometric algebra (or Clifford algebra diff name) into mathcad. THis would include multivectors, the wedge product and the geometric product? Not sure if there is any modding of mathcad at all for reference  

I would like to READTEXT from text file which would form a two-column matrix.  That part is easy.  Then I would like to copy the contents of the first matrix to a second matrix, then use that second matrix for other purposes, but unlinked to the first matrix.

Hello. I am a student at Næstved Zealand and we use the free trial version of mathcad here. I have gotten a new computer and need to download it again but i am not able to. I keep filling out the blanket where it says: Free 30-day trial of Mathcad engineering calculations software. But when i finish it says i need to wait hours to get an email with a download link. But i never get this download link i have waited days and tried over and over. Is it possible to help me please?

Hi there,Could someone please help me fix this corrupted file. After spending a couple hours trying to repair it, i suspect it is a font error or something.Please see zip file attached. Thanks in advance.Brett 

Hi All,Can someone please help me fix this corrupted file?  I have spent a couple of hours working on it, and suspect it is a font size error or something. (see attachment)Thanks in advance,Brett

Is there a way to automate the collapse or expansion of areas depending on user input above in a worksheet?  Maybe by use of JScript or Python?

I’m trying to develop a robust approach for analyzing different configurations of a four-bar mechanism in Mathcad Prime. I’m looking to determine the corresponding angles for the crank, coupler, and rocker based on the mechanism dimensions and input configuration.I’ve tried a few different approaches and, interestingly, I’m getting different results depending on how I formulate the equations. I’m not sure if I’m missing something fundamental in my approach or perhaps overcomplicating the worksheet.I don’t work extensively with Mathcad Prime, so I may be overlooking a reference, function, or recommended approach that would make this easier. I’m also finding it a little difficult to identify the right reference/example for what I’m trying to achieve.The ultimate goal is to build one generalized worksheet that can handle different types/configurations of four-bar mechanisms under the same set of equations, rather than creating a separate solution for each mechanism.Any suggestions on the

I cant get the license to work in my MathCad for the trial

I uploaded some Excel files into M365 to convert into Mathcad Prime 11. The files created did not open in Mathcad Prime 11. Can anybody please help. Please see attached zip file.

This month’s challenge is about tautochrone curves and isochronous curves. They are very similar. Both involve placing an object on the curve and allowing it to slide without friction. With a tautochrone, an object placed at any point on the curve will take the same time to slide to the bottom. With isochronous curves, objects allowed to slide from any part of the curve will have the same period of oscillation. You can think of the tautochrone as “half” of the isochronous curve, as it is only concerned with how long it takes the object to reach the bottom.In this scenario, the “top” of the tautochrone curve is at a height of 10 meters on the left side. The end point is at ( 0, 0 ). (The “top” of the isochronous curve on the other side is 10 meters on the right side.) Design a curve such that an object placed at any point on the curve will take the same time to slide without friction to the end point under the effect of uniform gravity. Examples of three possible solutions from Creo 13.

I have a student version of Mathcad 15 that I was using years ago.Now, I want to install it on a new laptop and open my old files, but I receive an error from remote server during the installation.Can anybody help me with this process?Picture below shows the error message that I receive while trying to install the software. Thanks, 

I do not recieve e-Mail from PTC when it says to go to my email during the acquisition of the 30 days trial license.

Hi, I have issues to get a license file. I can't run the software.I get: The remote server returned an error 403. Forbidden Can you help? Thanks Arek

I have two calculation sheets: One is L55-529.7255, and the second one is L55-538.6610. I need to import the functions E529 and U1 into the L-55-538.6610.And the values of E529 and U1 are added to E538 and U2. All the functions are defined with matrix notation. But when I apply the command “Include” the function E529 is ok in the sum, but U1, it says “this variable is undefined. Check that the label is set correctly”. But if you escrow down to the last sheet in the file L55-529.7255, you can see that there are no errors and that I am able to sum E529+U1.I tried in the opposite way, importing L-55-538.6610, using “Include” into L55-529.7255 and I have the exact same error. But I cannot find what the problem is with the U1 function when this is imported in L-55-538.6610 and U2 when this is imported into L55-529.7255. I am including the two files. The functions U1 and U2 are defined in the before last page, and all the sums are completed in the last page. The majority of the calculations

I am still using the old Mathcad 11.2, despite the difficulties with the new OSes. I asked to ChatGPT for help, but I did not get any solution. I wrote (see picture) two equations, and I asked to solve for variables p and w symbolically. Afterwards - and only afterwards - however I would like to capture the symbolic solution (in this case of variable w) and turn some symbols into numeric values and make relations with just few variables like w vs. r, so to obtain a function like w(r):= etc., that  I can plot it.As can be seen from the screenshot, however, MC11.2 appears unable to assign some variables the specified values. ChatGPT suggested defining a new variable and then “optimizing” it, which I tried using wR(r):= ..., but that approach did not work either.Of course, one could simply copy and paste the solution returned by find; however, I am curious to know whether there is a way to achieve the same result avoiding such a manual intervention.Thanks in advance for any suggestions or

I am a fun of Mathcad (the classic version in my case), but far from being an expert. So sometimes I come here, but recently I often use AI chats to query for basic help. I found that ChatGPT and Claude (free plans) are probably the most responsive models in my case. But they tend to not follow always my prompts that I am still using MC11.2 old version. But there are many other AI models around.So I would be curious to know what kind of AI models new and experienced users here prefer - if they use them at all.Thanks.

i Have PTC MATHCAD PRIME need a function to generate a cumulative sum sequence where Ui=0 and Ui-1 =0, iteratively calculating Ui+1 up to a 4094 rows , 1column vector. 

I am using Mathcad Prime Release 3.0 and DatecodeN/A print does not working.
