Hello @LucMeekes ! I am using prime 9.0.0 and I cannot seem to find an option to add multiple entries to a single plot like in this answer. I can just copy and paste the plot you generated, and it works, but I would like to know how it is done, please 🙂   Reference topic: https://community.ptc.com/t5/Mathcad/Multiple-Plot-Entries/m-p/652806#M925 

Hello mathcad 10.0 Prime User,I wanted to ask if someone knows how to use the the "solve-block" to find two missing variables in an equation. Or if there might be a different way? I am searching for h1u und h1o. And h1o depends on "a" and h1u.Thanks for any help. The mathcad-file is attached. Saro 

HeyMy file for my exam crashed while saving and now it wont open. See picture. Can you help me recover just a fraction of the data? Also Im not able to attach the file for some wierd reason.

Hello everyoneI've had the same problem as descripted here twice this week:Unable to activate Excel componentI work with an embedded excel table which contains a function. At a certain point I get the error message "Excel is busy; can't activate Excel. Make sure that cells are not being edited in Excel and try again in a few seconds." but there is no instance of excel open. Upon restarting mathcad and/or my computer the problem remains.Does anyone know how to solve this problem?Could someone please check the appended file so I can exclude an error of my sytem?Cheers!

Does FIND stop searching for a more accurate solution when it finds a solution satisfying CTOL?  For example suppose I want to find temperature to within .5 F and I set CTOL to .5.  Will Mathcad stop searching when CTOL is met or will it continue searching until some smaller CTOL is achieved?  Note: my Solve Block is solving for 1 unknown with units (BTU/min).  My constraint has units of degF.  I found that units can be applied to CTOL but then FIND does not work.  Also I have a case where I set CTOL to .4, but the FIND solve block found an answer (solution) at which the error is .53733 which is larger than CTOL.  So why is FIND returning a solution? PS:  My constraint is 0 =ABS(T1-T1x)  +  ABS(T2-T2x) 

Hello! I am working in mathcad prime 9.0.0.0 and am wondering why mathcad calculates end result units like this:why do the units on the results automatically display as such? To me it would be logical for it to display kip x ft as the unit since those are the units of the values being multiplied and is also a commonly used unit for moments or torques. Is there a way to get it to automatically show kip x ft as the units? 

PLEASE add a dark mode option and/or color options for the background and text.

Hello people 🤗 Mathcad 10 Prime User here,In my picture below you will see that the equation is giving me a very weird answer. I guess it has something to do with a vector problem, but I tried everything and can't figure out what the problem might be. And I also don't understand why my "header" is showing an error. The table from Excel should be my answer. Don't get confused by "yi"and "y" - it's the same thing, it can be ignored. I also send the mathcad pdf (i don't know why I can't send the actual file but anyways - it always said error) - all the equations are correctly written. Thanks for any help.Saro

Dear all, I'm exploring the functions:numerdenomAnd I've encountered the "oddities" in the joined MathCAD file (see what highlighted in pale yellow and the text; in pale blue some reference results for information) To be honest I suspect multiple bugs... If I'm wrong (i.e. we're not dealing with bugs...) , can someone explain me the logic under the quoted functions behavior, because I really cannot understand... Many thanks in advance & Best Regards 

Hi Folks, I have a system of three coupled ODEs that I'm trying to solve in Prime 10.  I seem to have a  syntax error, but the help files are so terse, I can find an example to follow.  I'm sure I'm making a basic mistake, but I can't figure it out from the documentation. I'd be most obliged if someone could point me in the right direction. The attached file actually has two different solution attempts in it.  The first is a state space solution with rkfixed.  I followed a short example from the documentation, but it doesn't work.  The second is the uses odesolve in a solve block.  I'd be happy if I could get either one to work, but the solve block version seems like it takes better advantage of Prime's features. Edit:  I figured out the problem with the odesolve solution.  I defined three of the initial conditions incorrectly.  I wrote x1'(t)=0  rather than x1'(0)=0.  That just leaves the state space

Hello @MN_2245665   With reference to this topic. I dont have mathcad 15. when I try to convert it to Mathcad prime 9, i get an error message: Thanks, Sam

Hello newbie here, (user of Mathcad Prime 10.0)I wanted to ask if anyone can explain how to use normal Iteration in Mathcad. Like, I have different equations and I want to create 5 loops or "intervals" to get my answer. I always used "solve block" for iteration, but now this won't work. I want to create something like this: I tried asking AI but it only gave me nonsense. I never used this type of Iteration on Mathcad before, only on Excel. Thanks for any help. Sorry if I wrote a little bit wobbly, English is not my native language. Best regards,Saro : )

How do I copy paste large data in first column of combo box? Rest columns I am able to copy paste the data but first column how to do that? 

I have three stacked blocks with widths denoted as B1, B2, and B3. Each block is 4 feet high, and the bottom elevation of the lowest block is defined by BotEL.The ground surface is represented by a set of known points with X and Y coordinates describing its sloping geometry.For each block, I need to determine the coordinates of two intersection points with the ground surface. These are labeled a1 and b1 for the first block, a2 and b2 for the second, and so on.The "a" points correspond to the vertical lines at the right edge of each block, where the X-coordinate aligns with the block’s right edge. The corresponding Y-coordinate must be interpolated from the ground profile at that X-location, The "b" points correspond to lines forming an angle θ (theta) with the ground as shown. A Mathcad and an image illustrating the problem are attached.I appreciate any help!

Buen dia comunidad, tengo un problema en la iteracion para encontrar un valor (Xcal) donde la condicion es que el valor calculado menos el dato del valor inicial sea cero (Xo = Xcal) o el error sea minimo. Por favor si alguien me pueda ayudar se lo agradeceria. Gracias por la atencion prestada. La version de Mathcad Prime 9.0.0  

Hello, I have solved some problems and formulas in artificial intelligence: Deepseek and ChatGPT then and converted them to MATHCAD format. There are no errors, they are well written, but Mathcad does not recognize formulas or numbers, it pastes them as text... Is there any way to solve this? Is it possible to use a programming language to use the Gauss Seidel and Newton Raphson methods directly in Mathcad? I have the codes in Python but I want Mathcad to generate the .mcdx document for me...

Hello everyone,eff.K shown in picture is radius of curvature along beam length and X is the array for sectional points.I have to double integrate eff.K to get deflection. How can i do it in Mathcad? Attached Mathcad 10 sheet.  

I would like to write a program to create a nested array. I have a column vector containing angle values. I want to iterate through this vector and create an array of arrays with each element being [cos(angle) sin(angle)]. I am sure this is not difficult, but the syntax is not clear to me at present. I think I have been writing python programs for too long.Thanks in advance for any help

Hello,Please see attached file. How can i get a constant value for (EI) to be multiplied by the results of the curvature y"(x)? Thanks,Sam

Make equivarent sine waveform that has maximum value = 1, average value = pi/2 and RMS = 1/sqrt(2). Below waveform has RMS=1/sqrt(2) but Ea=2/3 not pi/2. ,    Hard probrem. If you can make it, find the Fourier series of the waveform. Calculate the Ea and RMS values for 10, 100 and 1000 harmonics include. Symbolic evaluation by using below programming may causing a trouble.    

I use MathCad Prime. I have N/mm^2 *m*m. The result should be kN but it just doesn't work. I tried kN/m^2 for the f thing, but still doedn't work.

I checked other posts about this issue, and I couldn't find one similar to what I am doing hereI am wondering if that is because of the sin function or whatmathcad 9.0.0 file is also attached 

I am trying to assign the result of the symbolic solution of P to P so that I don't have to copy the result and assign it to P manually. See below and the attached mathcad file:is possible to write this so that the result of P doesn't have to be copied?I want to change this because if I change the formulas above, I dont have to re-copy the results

Found what looks to me like a bug. The error message is not very helpful and rather an indication that it is actually an unintentional bug.   In Mathcad the convenient prime operator is not available and so we would have to use Can't check if this way would work in Prime as I am limited to Express and that kind of 'programming' is a premium feature not available in Express. In Prime we get the very same error when using a scalar argument and vectorize   Any comments on this?   Prime 4 worksheet attached    

Hello,How do I set positive y-axis  in the downward direction in prime? Regards,Sam
