Hi,I have a cylinder defined as follows:and I would like to rotate it around the z-axis and represent it in a 3d graph.How can I do it in Mathcad 15?Thanks in advance,Enrique

I have a customer who is trying to transfer his Mathcad 15.0 from one computer to another. When I try to return the license from the computer that is registered, the option to deactivate is greyed out. I have disabled all firewalls. Am I missing a step?Thanks,Nick

Hi, does anyone know how to use a root hanning window within the coherence function of the signal processing extension pack ?I am using Mathcad14.Peter

Goodmorning everyone.As AUTOCAD user (the latest version that I use is the 2000) for several decades, I would like to know if it is possible an interaction between AutoCAD2000-mathcad-prime-3.1 or mathcad 15.Thanks for your kind attentionWith best regardsFM

How would you do this "If" and "Otherwise" operation in Mathcad Prime 3.1?  have no idea what command to use or how to start it.b=  0.85 if f'c=4000 psi               1.05-0.05*f'c/a000 psi  if 4000 psi < f'c  8000 psi                  0.65  otherwiseplease see attachment.

I am writing a program to calculate principal stresses from stress tensors.  The principal stresses are defined by a cubic equation.  The invariants (coefficients) of the cubic equation are calculated from stress tensors.  The stress tensors are first read into Mathcad from a multi-row file of stress tensors. Each row represents a state of stress at a node in a finite element model.  There are six stress tensors for each row in the file.   I am able to read the file row by row and assign the stress tensors to a matrix.  From the stress tensor matrix I am able to calculate the invariants (there are three invariants , I1, I2 and I3, plus a constant term, I0, for each row of tensors) and assign each invariant to a separate vector having as many rows as nodes of interest. What I have not yet been able to do is calculate the three roots of the cubic equation that define the principal stresses and output a matrix populated with the results by looping throug

Hello everyone, I have this problem with mathcad-prime-3.1: I import  data, with the use of READEXCEL, from a file with extension .xlsx. I made some changes in the argument of READEXCEL, then I deleted the changes. Nevertheless, many variables are no longer recognized. See example in the image below. At first, I modify the β1 index, then I delete the change and the error disappears. How to avoid this "strange phenomenon."Thanks for your kind attention.With best regardsFM

Attention Geotechnical / Civil / Structural Engineers,Please see attached a copy of the Mathcad file I'm working on. The diagram is based on the author of a paper using different software to analyze a pile pile group. I tried the same problem using the method of deformation, but I was getting the wrong answer compared to what the author's answer using the different packages. Can anybody tell me what I was missing in the equations or provide the equations. The author's answer is at the end of the worksheet.Regards,Moses

How can I assign geometrical and Mechanical properties to a series of reinforcement bars and have them saved on the system or pre-established so everytime I perform a calculation I simply pull out the bar number and the parameters automatically are displayed. please see attachments. Thank you.

After a harware upgrade, I've installed MathCAD 14 on a windows 10 machine.Printing worked at first, but doesn't anymore. (Nothing appears at printer, and M/S print to pdf produces corrupt files; but other apps are OK).Circumstantial evidence from the dates suggests that the Windows Updates KB3149135 or KB3163018 of 16th June could be responsible.Has anyone else experienced this? (I've posted on the M/S forum too)Thanks

I am trying to find the symbolic Fourier Transform of f(x). Please see the picture below for the equation. I know from hand calcs that the answer should be e^(-2*(pi^2)*s^2). Instead, I am getting the strange answer shown below. Can somebody please show me how to get the correct solution using Mathcad? Thank you in advance,Tommy

Hello.I've written a program which finds the resonance frequencies of a recorder (using 2nd order Runge-Kutta integration) for various open and closed positions of the finger holes. Actually right now I am trying to get the same results in MathCad as in my earlier Excel program, so that I can easily move on to using complex quantities. I have attached the file.I am pretty sure that the basic computations are correct, and one can skip over them. The problem is with the minimization. Things are very sensitive to the inital "guess" frequency (at the top of the program). If I am off by say about 50 Hertz I get nonsense. Furthermore the final frequency found drifts slightly as I change the guess frequency. It's also very sensitive to the CTOL.The fundamental frequency for the hole configuration set right now is 353.4 Hz.  If I guess around 800 Hz and search for the 2nd harmonic, I sometimes get around 743.9 Hz, but if I change the guess a tad I might get 347.1 Hz.Any help appreciated.R

I am a computer science student at the University of Aberdeen and I'm working on a project in partnership with Chevron in Model Code Design Tool. Its used to design pipelines in the oil and gas industry. Since my background is in pure computer science, I've never had a chance to use MathCAD before and my knowledge in this software is very minimal.In my project, I'm supposed to make a web app, based on HTML and PHP, and a database (possibly MySQL) and connect it with MathCAD for the calculation part. The basic idea is that a user can input new data through the web app, storing it in the database and when they need to process it, MathCAD should come into action. I have made a working front end and back end, but I'm not sure on how to connect MathCAD with the database. If its not possible, will it be possible to connect it with an Excel spreadsheet (to be used in the place of a database) and then access it? Can anyone guide me through this process? I am a total newbie in this software.Tha

  Hello, Everyone.  Thanks in advance for your time and help.      Best Regards.           Loi.

Hi,I have been using creo 3.0 for quite a few years and new to mathcad prime 3.0.I am facing problems with respect to inconsistency of units while initiating "Prime Analysis" from creo analysis tab.When I set a creo dimension, which is in "mm unit", as an input to mathcad prime variable, it is shown as "m unit" in creo analysis window whereas "mm unit" in mathcad prime worksheet. While the values are shown calculated according to mm.Moreover, the value of output variable in mathcad prime displays in "mm unit", however, when I see it on creo analysis window, it displays in "m unit", actually calculated in mm.Someone please advise me , what am I missing?

Hi Everyone,I'm using Mathcad Prime 3.1 to solve ordinary differential equation. I'm doing a practice ODE to learn Mathcad Prime 3.1. When I type Given and type the rest of the equations as provided in the examples, Mathcad is not able to read the function "odesolve". When I open a Solve Block and use the same, I get an error saying "The arguments of odesolve are not correctly specified" even when the arguments are provided properly as given in the example. I have attached a screenshot of the same. Please someone help me on this.

I have made a model in Creo and try to drive its dimensions from Mathcad. It works the first time but when I modify the dimensions in Mathcad I see no way of updating the corresponding dimensions in Creo. Anybody who know how?

Mathcad can solve aequation and give the solution directly. But I hope the values of the solution to be assigned to a veriable or a vector, how I should do?

Please. Help to redo the calculation shown in fig. so that paid offDiesel cycle (Carnot, Trinkler, Guelder-roses).
