Mathcad

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

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.

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.

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.

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  

We would like to transfer our Mathcad 14.0 installation to a new hardware due to a hardware replacement. Is there any advice about how to get an updated license file?

The following Mathcad code attempts to use a formula from Wikipedia to expand cos(n*z), but appears to get the wrong result. Comments? Mathcad code implementing expansion formula 

After a Wibdows 11 update some weeks ago, Microsoft Edge version 150 closes a few seconds after it is opened. This is not a problem for me normaly because I prefer to use Google Chrome. However Mathcad Prime seems to insist on using Edge.I have set Chrome as the default browser and then installed Prime 12.0.0.1 even though I use English as the Prime language. Still no good.Does anyone know how to get Mathcad Prime to use Chrome?Thanks for your help.

PTC is hosting two live webinars about Mathcad Templates: on September 8 and September 10. The content of the webinars is similar, but the times and presenters are different, so sign up for the timing which is most convenient!“Build Once, Reuse Always: Mathcad Templates” promotional imageYou’ll learn about how Mathcad templates work and why you’ll want to use them. Our PTC technical experts will be sharing best practices to get the most out of templates, going beyond the basics. That said, we strongly encourage beginner Mathcad Prime users to attend; this free event will accelerate your Mathcad adoption and have you greatly speed up your ability to make new projects in Mathcad.We’ll also be taking live Q&A at the end of each session. The webinars will be recorded, and we’ll make the replays for both available after the event. We’ll also make the presentation materials available for download as part of that replay experience.

PrimeConnect is also by request now a python library that connects python engineering applications with PTC Mathcad Prime. It allows python programs to generate editable Prime worksheets,  and retrieve Mathcad calculated results as native python and numpy objects.What is still needed is a brief manual on how to use it, but it is simple.CheersTerry

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 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.

If I upgrade my web account to a global support agreement will a mathcad 14 license be issued using the https://support.ptc.com/appserver/lm/mathcad/call_logger/callLogger.jsp tool. I understand mathcad 14 and 15 are no longer supported however this tool mentioned above is still present and mentioned in forums. I just want to know if it still will grant licenses if I upgrade my account to global support. If it does how do I update/upgrade my account to this? Has anyone else done this? We have used the non prime version of mathcad(s) for decades at our structural firm with hundreds of mathcad spread sheets. I have tried the trial of the latest prime and the conversion of the sheets is worrisome. ebooks using roarks and young will also not work. Not to mention probably not backwards compatible if edited with a machine on prime, then trying to open on one of our other machines with Mathcad 14.
