Mathcad

Hi all,  I have an issue with plotting a function on Mathcad Prime 11. For some reason there are missing segments in the plots of my shear-force diagrams. I'm not sure why this is happening, other plots I have made seem to work fine - any guidance would be much appreciated.  The plots and respective functions are on pages 9 and 17 of the attached document. Thanks in advance  

 Can someone help me on this? 

I am having a significant level of loading failures in 2025 with "Incorrect file format, file should be from PTC Mathcad Prime" and "File contains corrupted data" errors as the causes:.  23 cases are appended. What is most concerning is that projects that have been used to launch improved models a few days earlier as well as intentional project copies, both cannot be opened then or a few months later.   Is anyone else seeing an increase?  The "incorrect file format" is a new error for me.  It looks like it may be necessary to store PDF copies of projects, as some of these programs are 50-100 pages in length and will take days to weeks to reconstitute. Two .mcdx programs I tried to upload were rejected as having as having an incorrect file extension..  Is there something wrong with the title "250525, Tac7C+Weatherstation, corrected firmware, threaded slab heater, slope analysis.mcdx" ?

Hello,  We encountered the following message (shown in the first picture) multiple times when saving a Mathcad file that contains an object from AutoCAD LT 2024 (inserted using the "Insert Option"). After saving and reopening the Mathcad file, the AutoCAD object is deleted, as shown in the second picture. We found this issue on all machines running Windows 10 & 11. Kindly advise on how to resolve this matter.I am using Mathcad Prime Release 11.0 and Datecode11.0.0.0

I attached abbreviated work sheets. Question regards echo sheet. How do I pass secondary ohms to the matrix?  I can't seem to define the values as ohm(sec) in the matrix.  Secondary ohms are (ohms value) multiplied by (CTRW/PTRY).  I have a hunch that I don't have units set correctly in the definitions area. I made an attempt at showing values using the table function.  That was a train wreck except I can set units as secondary ohms.

Is there a way to imbed the str2num function into a lookup? Is there a means to automate renaming or concatenation of the variables in the first column of the text file? What is the type of variable is ["600"] ?  I guess it's not a string variable?

Hello everyone!I have a spare PC to use in case my current PC crashes. Is it possible to install Prime on both PCs using the same license? (Sorry for my ignorance!)Thank you for your reply.Regards.

I've now gone from Prime 10 Express to Prime 11 Express,  This allows me to see worksheets that have been created in Prime 11.  However, does anybody know if there are any technical or other capabilities in Prime 11 Express that are not available in Prime 10 Express?  I can't find any.   Alan 

Gentlemen, please evaluate my attempts to perform the development of an inclined cone, maybe there are comments and something can be corrected or replaced?

Hello All, Is mathcad prime-9 generally slowly in terms of Auto calculation or refreshing the values?  Also, if i change a variable , a lot of calculation  turns into a light font as if it is still processing the values as i am showing below.  Seriously terrible as compared with mathcad 15. Thanks,Sam

Looks like there's a way in China of converting Mathcad 15 spreadsheets to Maplehttps://www.bilibili.com/video/BV181421z7aJ/

Hi guys, I am having some issues with matchad, as soon as i move to another page I am not gettig units in my cal so this above is from same worksheet but outcome is different and i am wonderign its something to do with settings? Thank you Antony  culaton and the previous page is working fine can someone tell possibly whats going on?

hi, I'm having trouble with solver block in mathcad, i find the varaibles  

This season’s Mathcad Community Challenge is an open-ended creative challenge: design and implement a game within PTC Mathcad Prime! I’ll be hosting this challenge.   Mathcad Community Challenge Summer 2024: Game Gallery   For our purpose, a game is defined as an interactive, structured experience with an achievable goal that has a beginning state, then allows for user input that can advance the state as the user tackles a challenge or solvable problem, followed by an advanced (intermediate or ending) state.As a good example, see my first reply to this challenge below. This challenge will be quite lenient on what a game is and the production values you put into it, though you should test it and make sure it works as intended before submitting it.   Games take a long time to concept and execute, and for that reason, this challenge’s submission period will last until the end of September (September 30, 2024)! Expect the blog write-up on Mathcad.com to come out sometime in

Good morning, PTC Community: Objective:Given circle ID, and fixed value "a" for the equivalent in area & perimeter ellipse, goal seek the value of b.I am encountering a "These units are not compatible" error. See attached.Using Mathcad 10.0.1.0.Your assistance will be appreciated.JT

Hello, i like to calculate  force FA depending on three variables hS, hA, Hz. Mathcad calculates FA and put into a vector. Finally, i like to have the maximum of this vector. Typing max(FA) gives back the whole vector not the single maximum value. Also for mean and other functions. Thank you for your help.

Hello, I'm still new to mathcad and I'm trying to understand why this error occurs. Because my z is defined but don't seems to work in my integer. Could somebody explain it to me ?

Hi,I could not change Matrices output unit as deg.I am using mathcad prime9GSVP

Bonjour,Je travaille sur la conversion de fichiers Mathcad vers prime et je me demande quelle est la continuité dans prime pour ce qui est des handbooks, y-a t'il la même fonctionnalité dans prime et si oui comment la convertir depuis Mathcad.Merci d'avance 

Good morning, I need an integral of the function as shown below.  This derivative of the antiderivative does not return the original function. Turning to Mathmatica, here is the correct answer:  Ideas? 

  This month’s challenge is based on spin gravity and emphasizes creativity! Spin gravity is a method of creating the sense of gravity in a low- or zero- gravity environment using rotational movement. During this circular motion, objects with mass feel a fictitious centrifugal force “pushing” them away from the center. This force can feel like the gravity we experience on Earth.   You can either design your own space station / vehicle or choose one (or more) from science fiction books, television shows, movies, video games, or other media. Then create a Mathcad worksheet to calculate the following: Radius of your spinning object. Centrifugal acceleration in both distance units per second squared and g’s (acceleration due to gravity at the earth’s surface). Note that your vehicle / station does not need to be 1g. Less than 1g makes it easier to move. More than 1g would help improve your jump shot on your eventual return to Earth. Angular velocity in radians, degrees, and rev

Dear all? I'd like to have some deeper / practical information on SVD function. From theoretical lectures it seems to me that Singular Value Decomposition could me a useful tool to tackle ill-conditioned matrix in eigenvectors search for homogeneous linear system. It appears also that SVD can solve a variety of problems; that does not help that much me as explanations are often at a too "high level"..... The material in MathCAD help is, sorry to say, in the same league: too abstract...I had also a look to the only one post on similar subject, and again sorry not so easy to be adapted to my problem (not so specialized by the way...) Could you:1) confirm me that what I've understood from theoretic is reasonably correct 2) give a more workable example: for example the search for eigenvectors (linked to eigenvalues) for a linear system 4 equations in 4 unknowns (using the MathCAD SVD algorithm)? The best would be that the square matrix linked with the said sys

Good morning everyone!I've been using Mathcad (now M15) for decades, but I've never seen an error like this. Could it be because I only have 4GB of RAM? I'm really not sure what to do. Thanks to anyone who can give me some good advice.Regards.  

I'm using the "include" function to bring in variable values into work sheet.  I would like to bring in variables from a second work sheet.  I'm not always interested in the values of those variables but the expression in the worksheet that defines the variables.  Problem is that the variables are from a set template but the sheet maybe from a different project. Is there a way to concatenate or suffix the variables from the second sheet within the sheet where the include function is used separately of each sheet? As an example, Z1MP from sheet one could be defined as 85%*Z1L or a number with units.Z1MP from the second sheet may or may not be defined the same.  So I would like to bring in the value or better yet, the explicit expression and rename Z1MP from the second sheet as say Z1MP2..   Maybe explicit representation of the second sheet is reaching too high and I have to settle for the numerical value of Z1MP2
