Hello,Attached is a Mathcad Prime 9 sheet. I would like to perform linear interpolation as explained in the sheet. Thank you for your help.  Best regards,Sam  

Hello,I am a beginner in Mathcad using Prime 10.0.0.0 Educational Edition. I want to calculate the kinetic energy of a mechanical system so I have to define a time-dependant function, but I'm not able to do this. I want to calculate the symbolic expression. I write the function as alpha(t):=[function including t as time variable] and I don't get any errors, when I try to use this function later I get the error "The variable is undefined. Check that the label is set properly".I don't know if I'm using the time variable t wrong or it's an algebra problem.Any ideas? Thank you,Andrea

I am using Mathcad Prime Release 10.0 and Datecode10.0.0.0Fatal Crash when copy/pasting text and math from one sheet to another. Window closed. pop-up opened and disappeared before readable. Lost whole days work over several tabs open.Disappointing that there is no autosave or periodic save setting, and no recovery mode to recover some of lost work.Here are the errors that I facedpop-up box flashed up briefly then disappeared before readable.

Hi,I have a piece of programming but I'm having trouble understanding all the steps and the programming to reach the product graph.  Can someone document what is happening in the attached?  I hope it will be a step to understanding more complex programs.

Can someone help me to redefine a variable in a for loop or get me moving in the right direction?  I am new to Mathcad.I am calculating a standard step gradually varied flow profile in a steep pipe.  Pages 1 and 2 are inputs and  creating functions that define the geometric properties of the open channel flow in terms of flow depth (y)In the solver block is the energy equation with upstream energy on the left and downstream energy + friction loss on the right.  I want solver block to find the downstream depth (yd) that makes those sides equal, which I get.  (note: the velocity V and friction slope Sf terms in the equation are functions of y, so I can't solve algebraically)My problem is I need to repeat that step by step along the pipe.  for simplicity now I have (100) 1 ft steps in a 100 foot long pipe but those values are arbitrary until I can get the for loop working.In the for loop, for every step I want to redefine yu equal to yd.  I want to be ab

Hello everyone!In the attached photo, I perform a topological analysis starting with the graph of a given system. At the end of the calculation, the two matrices β.t and Q.f should be equal, but instead they are different. Why?Thank you to everyone who will respond.Bye!

Hi all:I am looking for help/tips regarding more efficient/practical ways in MathCAD 15 to perform recursive calculations as it relates to creation of arrays, vectorizing the arrays (row by row), and then augmenting these data vectors into a final array.  I have attached MathCAD 15 file to illustrate my questions.The attached file is intended to perform a least-squares fitting of optical wavefront data (optical path difference data) to a set of Zernike polynomials.  I have tried to describe each portion of the script so that it is easier to understand what I am trying to accomplish.The first portion of the script creates two arrays (rho and theta) that contain the respective values over the unit circle.As shown, the next section explicitly lists the mathematical form for of the first 36 Zernike polynomials and evaluates them at each coordinate position.  Once evaluated, individual arrays are created for each, evaluated Zernike polynomial so that in the end we have 36 ind

Hey folks, It`s me again...I have been using Mathcad integration with Creo, but recently one of my friend had asked me "if we can integrate SOLIDWORKS (or any other CAD tool) with MathCAD." I kinda got stumbled on this and been wondering. I was checking out few resources in all PTC & Dassault portals and all I found was the Legacy Mathcad integration with the very old versions of Solidworks. That gets me here seeking answers from y`ll. Can Mathcad Prime 10/11 be integrated with Solidworks 2024 or above/below versions???Will be waiting for your answers...Ciao,Srikar

Hi there, as shown in the following screenshot, could someone kindly tell what is wrong with this mathcad operation? There are are same values of 6 inches. But still it is showing "NOT OK". I would be much obliged if someone can resolve my this problem. 

I am using Mathcad Release N/A and DatecodeN/AHi Team,One of the user is not able to login to MathCAD App on their laptop but can login to it on Web portal.Could you please help on this one?Thanks,Abhishek MHere are the errors that I facedError -The HTTP request was forbidden with client authentication scheme 'Anonymous'.

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/
