Mathcad

Many of my Mathcad worksheets are large (50+ pages).  As the worksheets get larger, the screen refresh rate becomes so slow when using the drag slider bar that scrolling through the worksheet becomes very difficult.   This has always been key source of frustration when using Mathcad for large models. I had been working on a large worksheet for a bit after upgrading to Mathcad 12 when I realized that the scrolling was as responsive as any Microsoft Word document – very smooth with no noticeable lag up to any reasonable scroll rate!  That was not one of the explicitly stated new features in Mathcad 12 – so I didn’t notice it immediately (sometimes you don’t notice the things that just work the way you’d expect them to work).  I really appreciate some of the other enhancements in the Prime 12 release like Find/Replace with subscripted variables (another large worksheet issue) and the enhancements for native plots, but the scrolling improvement ranks near the top! 

I have been a paid subscriber to Mathcad since the late 1990’s. As a former a beta tester and advisor on new features, my interest and commitment to Mathcad is substantial. However, I am concerned about the future of Prime when I see more discussions on it not working rather than use.Yes some old problems are addressed with each new release. But installation and operation issues are starting to out number Topics on using the software to solve engineering and science problems. Even just upgrading to the new version or obtaining the new license keeps changing, adding to the frustration.For many of us, Mathcad is our only reason to use PTC’s products. Please do not make it a reason to be the last.   

It is said that in order to run PTC Mathcad Prime, you must have the latest Microsoft .NET Desktop Runtime 8.0.x package for Windows x64 installed on your computer. At the same time .NET 8 end of life (EOL) is November 10, 2026 – after this date, Microsoft issues no further security patches or bug fixes. EOL means real risk: unpatched vulnerabilities, compliance failures... Am I missing something? It seems rather serious. It looks as if I have to skip the latest version. Does Mathcad Prime v12 work with .NET 10?

i cannot run the program. I am stuck in an obtain license loop. I am sure there is a way..

Please help me what am i doing wrong?Mathcad Prime 11.0.1.0

Hi,I am using root function to solve a function for different variables (variables are vectors) but some of these values don’t converge as there is no solution. How can I skip these values that don’t converge and make a table for those values and solve the rest? I have attached the MathCAD zip file.  Thank you!!!

I purchased and installed Mathcad Prime 12. However, I now understand that, because I am using a Dutch Windows 11 OS, Mathcad does not start. First of all, I find it unbelievable that PTC does not mention this very clearly beforehand, but that you are only confronted with this after purchasing. What really makes matters worse is that, although you start from and with the English website, you are redirected during the installation process to a Korean website, which is unreadable. So now I am stuck with a Mathcad version that I paid for and for which the 1-year period has already started, but which I cannot use. I would like this situation to be resolved ASAP.

I am trying to copy a 1xn matrix developed in mathcad prime 11 and paste it into an excel like table in ansys mechanical to build material curves for stress analysis.  I cannot for the life of me figure out how to do what seems like a simple task.  Is this an easy thing to do?

Hello, i have problem with installation of mathcad. I couldn't go next from ,,Aplication Selection'' window so i haven't installed mathcad yet.Thanks for help.

Hi, I am trying to solve an ODE to model a “Ball and Cone” tuned mass damper. The equations simulate a ball mounted inside a pair of cones with mass on top. The ball oscillates up and down an inclined slope with a curved region at the apex between the up/down slopes. I am using Radau solver as it is a stiff equation. Adams/BDF “does not converge”. The 1st solve block uses a simplified simulation for base excitation of the TMD. Using Radau with modest levels of damping the first solve block result gives a discontinuous response which should not happen given the inclined slope is a tangent to the curved section at the apex. Any ideas how I can correct this discontinuity would be appreciated.I tried using sigmoid transition functions (2nd solve block) for the step between inclined slope and radius but this gives a large number error.The 3rd solve block includes an extra degree of freedom to simulate the tower on which the damper is mounted, which is the aim of the program. This won’t solv

We run FLEXnet on our company license server for Mathcad licenses. Currently on version 12. Our Mathcad license file has both permanent and subscription licenses of Mathcad Prime (and 15) in it. When a user runs Mathcad, the server first assigns a license from the permanent pool. If that pool fills up then it assigns a license from the subscription pool. The problem is when a user receives a license from the permanent pool, the license type shown within their Mathcad software says Home Use when it should say something like Commercial. This results in certain calculations being inaccessible and causing errors in their worksheet. But if a user receives a license from the subscription pool, the license type is shown as Subscription which should be fine.I would like to know why our Mathcad license server is serving us Home Use licenses instead of the commercial licenses we paid for, and how do we fix this?

how can we convert xmcd files if converter is not working, is this a bug any workarounds?

One of the things that has always been a feature of these forums is the willingness of experienced users to provide help and guidance to others.  In addition to help with how to use the Mathcad software the forums provide a place to gain advice and assistance with dealing with engineering challenges, problems that go beyond the simple application of the software to understanding the basic physics of a situation. One remaining impediment to this  feature is the inability of Prime to save a file in an earlier version of Prime; a file asking a question in Prime 10 can be read in Prime 11 or 12 but if this file is modified and saved by a later version and posted as a reply it cannot be opened unless you have a more current version of the software. This is a great marketing tool--”Here’s your answer.  To view it you must buy the latest version of the software!”   But it’s a lousy way to share information.  The forum is littered with requests to modify a file to enable a specific version to

I recently purchased a student licence for Mathcad Prime 12. After download, unzipping and installation, when I try to open the app, it automaticly crashes. After analyzing it with Eventviewer it seems that the app cannot locate resource 'worksheetresources.xaml'.What can I do about it?

Hello,I have tried to upload the mathcad file, but it does not allow me. The following was working in mathcad 15, but it does not evaluate in prime Thanks,Sam

Hi,I have a file that can’t be opened by Mathcad Prime.I just get the message “File type not supported”.Anyone got any tricks to find ways to repair the file?I attached the file here in .zip format since mcdx format is not supported.

Hello!A new year and a new crash unfortunately.I was working with this document and saved it. The next day when opening it i just get "The file type is not supported".Can it be recovered? Would help alot 🙂I attached the failing document and a log fileKind regards, TomPrime;7.0;FileNotSupported;Crash;MathcadPrime
