Dear all,   I'm using Mathcad 15 M030 for analysing data. I got the "out of memory" error message if I paste the file I have attached in a mathcad table. I know that the topic has been already discussed in this forum but I didn't find any workaround. Is there in the meantime a new solution? Thank-you very much for your support.   Regards

In my 2D plot when I process about half million time steps I get an error message: "Unable to plot this too many points"   Any idea or clue where is wrong?   Regards

Hey, guys! I'd like to ask you to help me solve two quizzes I stuck on. I guess I think of all possible solutions and even consider asking to write my paper on Math to solve these: 1. Which number is hidden behind the question mark? 2. What time does the last watch show?

I've been trying to figure out how to use mathcad since I didn't have any lectures about it in my university and I'm asigned a task that says to solve the equations by using mathcad. Could anyone help me out? I've pasted 2 photos of variables that we know and equations from which we need to find I1,I2..etc

Hello, What is the difference between a .mctx file and a .mcdx file. I know the former is a template, but it seems to be exactly the same as an mcdx.

Dear Everyone, How can I solve the root of equation as matrix as picture attachment (Red Circle)? Many thank for replying  

Hello   I'm trying to comptue the stress in ground below a circular loading, at differend depths, at different locations below the load.   The formula which I use, include Bessel's function. Reference to the formula can be found here: http://onlinepubs.trb.org/Onlinepubs/hrr/1963/39/39-004.pdf   The used formula is the equation 3c.   The formula seems to give reasonable answer with most locations and depths, but some depths seem to give strange stress values (peaks in the graphs).   Could someone explain why these errorneous values appear and if there is a way to overcome this problem.   Thank you for your help.

We have a Pi day - a math day - 3.14 today! One suprematic composition: "Cross, Circle, Birds (a duck), Fish (a flying fish) and.. Pi number". Can you create more fine and/or more interesting animations? The origin Mathcad-sheet is in attach!  

I have Mathcad 15 and I wanted to use excell spreadsheet to show up the calculation results over it and also to use excell spreadsheet to read values typed in an excell table. But I have noticed I can generate only maximum rows 65536 and it looks like Mathcad 15 handles the old version of Excell 2003. Is it possible to do anything to use new version of Excell which can handle up to 1048576 rows and16384 columns?   Thank you for any help

Hello PTC Community,    I am attempting to utilize my Moment-Curvature Interaction (M-C) to calculate beam rotations and displacements. Currently, I have a worksheet that writes my M-C data to a text file (not included here); the attached worksheet reads the data file, creates a linear interpolation function describing moment as a function of curvature. Next, I have a simply-supported beam loaded with equal symmetrically placed point loads (0.5P); I have defined the moment diagram as a piecewise linear function of length (x).    My goal is map curvatures across the length of the beam, using moments as the method for "matching" the curvatures to length. The next step(s) of calculating rotations and displacements are straightforward after this.    The attached Mathcad Prime 3.0 file attempts to solve for the corresponding curvature that satisfies M(c)=M(x), where c = curvatures from the interaction diagram, and x = position along the leng

I'm new to Mathcad so hopping this is just a setup problem. I have set up an equation to solve for t with known variables, one of which is exponent n.  Now i need to rearrange the equation to solve for n.  Please see attached. I don't understand why I'm getting No solution found.  I am able to solve this by hand and also using a free on-line math web page i get the same solution.    Help is appreciated.  

Could anybody help me? I'm attaching the screen and file.

hello i am  having a problem i can't get inverse sin to work in MATHCAD PRIME 4 does anyone know to to get it to work? -Anders Ugilt

I am new to Matcad and the ODE Solve function I am confused on how to use the ODE solve function  Any help will be greatly appreciated! Thank you!  

I see one very strange bug! I have had solved a system of 2 algebraic equation - not correct solution! I have simplified its - correct solution! Do you know about it?

Hello, I have captured I-phase and Q-phase (quadrature) data of a radio signal with QPSK modulation.  The two data are in two separate text files with an array of data in a list. How do I do FFT using Mathcad please? Thank you

We are unable to load images - started with Prime 3.1 so I installed Prime 4.0 - still can't load image. I click Ctrl+4 and it opens the dialog to search for image file - select file click open and only thing in the file is the dialog box 'Browse for image' I tried .jpg & .gif images same result. Any help?

I am currently using IE11 and most often (like now, but not always !) when trying to access Communities from PTC Mathcad page I get the message “HTTP 500 Internal Server Error” / “This error (HTTP 500 Internal Server Error) means that the website you are visiting had a server problem which prevented the webpage from displaying”. Have someone happened the same or have any idea why ? (I’m posting now within Chrome).   Best regards, Liv.

Hello,   Does Mathcad have any function to integrate an array without doing a polyfit? If you see attached, I have a 14 point array and would like to find the area under the curve. What would be the best and cleanest way to accomplish this? (Note: I had to attach a picture because it wasn't letting me attach a mathcad file for some reason)

Hi,   I have a question about Mathcad. I want to solve an ODE-system with Parameters. I want to use of Stiffr or Stiffb as a ODE-Solver. I have a minimal example in the file. See also the screenshot. What can i do, to find the error in the code?     I hope someone can help. Thanks
