Mathcad

HiI am trying to find 4 unknows from an equation. But its giving me "0" as a solution. I have eight know variables in the equation, while I want to find the rest of 4 unknowns. Your help would be highly appreciated. I have attached the sheet of Mathcad 9. Best,Waqas  

Having a problem here, every time i try to perform a simple matrices multiply function, it shows as invalid array index , but surprisingly the same thing has worked in other systems.Please help. Have tried defining everything separately but the problem persists.     

We are finishing a Trial version of Prime 9. We have a Gold Support and need to enable Prime 9 License Management. I am not sure if that should be Cloud, Floating, or Fixed.Please enable the Prime 9 License. I am familiar with the various licensing methods.

Hi, Have tried all I know (which is little) for a couple of days now.  Could someone explain all the steps including how to set up the Visual C++ Community IDE steps to get the provided multiply() custom function to work in Prime 9? Cheers Terry    

Hi, I'm having trouble finding a symbolic solution I can use in an excel sheet for later use.I am aware that it's mabye impossible to find a symbolic solution. But I was hoping it was, And that you guys could help me? All the values is >0 Erik

I am using MathCAD for the first time today, and have a problem that requires your assistance.  I have to create a waveshape, and I do so, but the points are separated by 1 unit, not the 1 microsecond units that  are the reality.  For this reason, I have no idea what the output of the FFT X axis is.  I've given it no frequency reference, so is it using 1 Hz as the basis for the difference between each point I've entered (not the truth).  I'd like to know how to get this software to accept 1 microsecond as the difference between each point that I enter.  I also need to know how to interpret the output of the FFT.  The spreadsheet is here: Re: How do I change the graph in the attached file... - PTC Community There are various example mathCAD sheets attached.  I've tried various things, but can't get them to work. Thanks. 

How do I change the graph in the attached file so that points are all 1 microsecond apart? Using MathCAD 9.0, PTC.  The latest.

Hi have successfully compiled the multiply(a,M) example custom function but have a few questions. Q1> Do you compile for x86 or x64 seeing as PTC Prime is 64 bit? Q2> Where do you find the custom functions as neither the Prime menu or the search for all functions has a section for custom functions?  Mathcad 15 search had a specific spot. Cheers Terry    

I have an old Mathcad file (14) I convert it to Prime 9 but the code does not work. Please help  

Hello, PTC community,   I defined a function in Mathcad prime 9 for plotting the displacement response (Y-axis) versus time (X-axis). This plot is for a single time period T.  I want to get the maximum displacement (Y-value) from the graph for each time period T.   For example, I want the maximum displacement values from the plot for Time period T if T= 0.02, 0.2, 4. eg T= 0.2        max. displacement: xx T:0.4          max. displacment xxx and so on.   I attached the mathcad file and it imports a text file containing earthquake data which is also attached for your reference.    I would really appreciate your help.   Thanks, Abdur    

I am attempting to evaluate a ground motion data set using Newmark's method. The programing routine augments displacement, velocity, and acceleration. I then need to plot the displacements vs. the time period as it varies from 0.02 to 4  in steps of 0.02. When I define T I get the following error :  I don't think a local definition with in the routine will yield accurate results. The routine needs to run as a function of T.     

I am unable to verify or access my mathcad license.EmailI purchased it a year ago, and would like to use it on another computerPlease let me know the steps to activate and use it, and how long it lasts. Thanks.

Join Anji Seberino of PTC plus guest speaker Dave Martin (of the Creo Parametric YouTube channel) in Mathcad for Mechanical Engineers, the second of our industry-focused webinar series.In this one-hour webinar, you'll learn what mechanical engineers use PTC Mathcad for, and why engineering calculation software is a perfect fit for mechanical engineering workflows. You'll watch examples (and be able to download the files involved) of real-life problems solved using Mathcad Prime, and you will also see the awesome integration Mathcad has with 3D CAD software Creo, which will increase your efficiency, reduce errors, and help document your design intent. We capped off the webinar with a live Q&A session. You can watch the webinar replay at your leisure!

While trying to activate my license during the installation I'm getting "The remote server returned an error: (403) Forbidden."

How do you go about getting to the next "step" in a formula? Like in a division situation where you have filled out the numerator, and you want to get to the denominator without using the arrow keys. Or in an if, then statement, getting to the next gray box? Or to the end of parenthesis in a formula? In short, how do you avoid using arrow keys to get to the end of the formula you are writing? thank you

Why am I getting an error when I move g below k? Shouldn't global variables work where ever they are used?   -->   so, this seems to work ... ... So is it not possible to have global variables inside global variables? if so, why did the first set of calcs work?  Thank you in advance

Is there still no way to have custom keyboard shortcuts? I found posts dating back to 2015 saying there is no way to do that in Mathcad. That was the latest post I could find. Any chance that has changed since? Ctrl + Shift + ~ is super awkward to do for global variables. thank you

Hi,I have an old license file for Mathcad Prime 3.0 (c. 2016!), but no longer have the download file or access to the software due to an OS upgrade on my computer. Is this something you can help me with? I'd like to use MathCad Prime again. It seems as if I can't access the knowledge base, the link won't work to allow me to view the installation guide for 3.0 that still exists in the help files.Jeff

how would you do the following in Mathcad:  if  (x = 1  or x = 2)     return "yes"else     return "no"  thank you.

The plot is changing enormously when ode solve is used. Any suggestions? 

I have enormous number of .xmcd files needed to be converted to .mcdx. Inside most of them there are links to each other. Considering nested structure of my files and the fact that you can not choose the whole folder for nested convertion in built-in MathCAD Prime Converter I need to automate at least filling Converter with list of files. Would be even better - to make the whole process fully automatic. Have someone done this before? Is there any API for the Converter? Nothing like that was found by me in the PTC support database 😞There is some kind of workaround - to generate multiple paths to files relative to the root folder and join them with " "`s but resulting string is far too long to be accepted by the FilePickupDialog of the Converter. Too many files needed to be converted.

Currently using, Prime 9.0.0.0. In ANY version, is there a way to have a simple database query like return "weight" from "AISC Shapes.xlsx" where "Name" = "C10x15.3"? Or workaround? Is it possible with the tables you can create in Mathcad? I can create the table if need be.Thank you in advance.  

When installing 14.0 I get a message saying this is an upgrade and to enter the old serial number. I had 7.0 and the s/n was PU02802D00549 which it does not accept. I still have the 7.0 CD, I put it in the DVD drive and provided the path but it can't read it. I had this same problem in 2017 and it was a ridiculous pain in the butt then, I shouldn't still be going through this aggravation. Fix it already sheesh.

I use the student version of PTC prime 9.0 on my office computer (windows). Primarily I remote in from my Macbook, but periodically I receive the issue:Cannot checkout an uncounted license within a Windows Terminal Services guest session. Is there a way to solve this issue remotely? As a student I don't have support phone service

When i want to register and have free mathcad trial there is written that can reached maximum number of licens. I have this program on my PC and i wanted the same program on my laptop. Why cant i have same program on other device?
