Mathcad

I'm tired of looking back at my work and seeing what did I set my variables equal to. I'm working on bending moment equations for the same beam at different load combinations. For load combo 2 I'd like to calculate the moment at the same spot as I did for load combo 1.. So x_lc2 ;= x_lc1 but I want to see the formula for x_lc1  like this x_lc2:=x_lc1=l/2. I'd like to see something similar to how excel would let you 'step in' to a formula. I know it feels kind of redundant but I just need that visual verification for everything I have to use this sheet for another project. 

I need to upgrade numerous computers, all of which have licenses for Prime 6. We have Mathcad Professional licenses which we get to upgrade to Prime 8.  My questions are.....  What are the steps to upgrade to Prime 8? Do I need a new license or can I use the same license that is on the current laptop using Prime 6? Any help in this matter is greatly appreciated.

Hi Guys,  I am trying to use solver block to find 2 variables. The solver says the solution cannot be found even though the solution exists. Please help me out by checking the constraints. Thanks,

Hello, Everyone.From the following : Plot Intersection-points of the "green" and "pink" ?     Thanks in advance for your time and help.         Best Regards.  

Hi, I'm trying to convert some excel sheets into mathcad,this particular one uses the summation function for variables features to be included, I've set up a table list to define the variables, these are calculated earlier in the document so I didn't want to simply input the values as they could change. I'm having trouble with a fewof things1. if i include beta.yi in the equation it displays the result as a matrix rather than a single answer     a. I've managed to crowbar this to work with beta.y which as it is the same for both values (50 deg) to get a result but i'm aware that this isnt the correct final solution2. the summation results are double what i am expecting, by tweaking the "n" value from 2 to 1 the results match but don't match what i understood how the function should work as    a.      i=1           the starting value of the summation    b      n (n=2) 

I'm trying to insert an Excel component in Mathcad Prime 7.0.0.0, and I keep getting an error that Excel is busy.  But Excel is not running.  I have checked the task manager, and Excel is not open.Even in the list of background processes, Excel is not running.   Read Excel seems to work fine.

I'm playing around with selected elements of a vector, or array.  Suppose I only want elements 2..6.  Why does Mathcad fail when using a range for the index, but defining an index as a range does not?  Curious.Thanks in advance.

Hi!   I have very basic questions and problems with summation operator. Please see the attached worksheet for examples. First question, I'm not just able to understand how the high lighted sum (13) is calculated?   Second example is shown also in the worksheet. How would you use the summation operator so that you could prepare worksheet template and define the n in the beginning of the calculation and then the formula adapts with the amount of n? I mean so that you don't have to change the formula by hands every time the n changes?   Thanks in advance and sorry for the beginner level questions 😣   Br, Harri

Here's what I found in my pantry!Happy New Year!

The best gift for me from Santa is Animation tool in Mathcad Prime! (Prime 10 I hope) My New Year's Story.I don't believe in superstitions like jinxing a person, but...I ran skiing early in the morning on January 1st. A grandmother was walking towards the park and said: "What a fine fellow you are! They are still sleeping, everyone has a headache after yesterday's drinking. And you are skiing!"I went 100 meters, fell and broke my skis! I returned home on foot - the Mathcad does not work! Need to reinstall!

I solved the equation, but I did not like the answer in form. I expected I decided to try the vaunted artificial intelligence portal. Here is what I got. I immediately remembered the sensational story about artificial intelligence, which was instructed to broadcast a football match instead of a human TV-operator. The task was quite simple - to point the TV camera directly at a soccer ball - a smooth round object moving across the field. So, at some point, this artificial intelligence lost the ball, began to look for it and... captured the bald head of the referee, who was running around the field. So TV viewers - football fans until the end of the match had the opportunity to admire the bald referee.  

I am a beginner. When I try to solve a  differential equation problem, the "simplify" tool can not recognize the Sin(t)^2+Cos(t)^2=1. I have to simplify the equation manually. The attach file shows how I do this now. Is there a solution that Mathcad can handle the identity relation Sin(t)^2+Cos(t)^2=1.?

How do i get rid of this warning message from prime  

I'm very new to Mathcad, but getting the hang of it.  I admit, plotting eludes me.  I'm trying to plot one column of data against another in an X-Y plot.  I just came across this post that explains you can't do this.https://community.ptc.com/t5/Mathcad/Needs-help-with-Plotting/m-p/273538#M106881 If I understand correctly, I can't plot a vector over a range.  Good.  I don't want to.  I already have two vectors (at least I think so), but when I try to plot them, I only get the first and last data point. Seems like the Chart function works well.  I have really tried to use the PTC Help, and I have found it really lacking for the beginner.  Any suggestions on other resources? Many of my datasets and use cases are simply a range of X and Y data.  I may have multiples of each, x1 vs y1, x2 vs y2, etc, all plotted on the same X-Y plot.  My goal is to plot several curves, each with their own X-Y pairs.   Do I need

Hi all, Please suggest, how to do goas seek  in the below attached calculation - mathcad prime 3.1

I can not install my Mathcad 14 on my new PC laptop with Windows 11. Please help. Thank you.

Unless I missing where it is, I think this forum would benefit from a dedicated, user-defined (UD) functions-only sub-forum.  Generally, the poster would link a topic of discussion back to the main forum for discussion. That way, the UDF sub-forum doesn't get loaded up with discussion.  It make solving some problems quicker by searching an existing UDF. I have many UDF's that I would like to share but just dropping these in here makes no sense.   Regards

On the occasion of the turn of the year, a four-leaf clover/shamrock is shown in the attached file (Mathcad 14) as a lucky charm. Unfortunately, I can't color the area enclosed by the contour. How can this be done?Kind regards, Alfred Flasshaar

Version 6.0.0.0 of the Ptc.MathcadPrime.Automation.dll assembly is resulting in an COMException being thrown, which is preventing the ApplicationCreator object from being constructed. I have had no issues with version 6.0.0.0 assembly before these last few days. I have replicated this condition using the same assembly for version 8.0.0.0, without any errors. What can be done here that does not include upgrading or downgrading the version of Mathcad?

I've written a function C with 2 inputs: a scalar and a vector; and 1 output: a vector. When I evaluate the function for a certain input there is no problem. However, when I try to compute the Jacobian of the function I get the following error: "The array index is invalid. The index must be an integer, not less than ORIGIN, and not greater than the last element."Strangely, when I get rid of the two bottom entries of the output vector of the function C, I get no such error, it produces the Jacobian matrix one would expect it to. This leads me to believe that the issue is in q_3. (I have made sure that 3 is no subscript but an index)Can anyone tell me what the issue here is?

I have my own versions of Prime 7 and Prime 8.  My company uses Prime 7.  Is there any way to take the Prime 8 files that I created and convert them to Prime 7?

I have a Mathcad file where many of the XY plots get larger when I open the file.  If I drag the plot handle to scale them back to their normal size, they get large again the next time I open the file.  This started happening with Mathcad Prime 8, and it only happens to one file, so far.  The left upper corner of each plot remains fixed, its the bottom right corner that changes location.  There are many plots in this file, and it is getting old having to resize them all each time I open the file.  These are the embedded plots, not the Chart Components.  This file is being opened from one computer.

Hello, I am evaluating Mathcad Prime 8s file converter capabilities through the express trial to convert 14 and 15 files. The converter tab is grayed out and I cannot click it. Any suggestions as to why? 

Between Christmas and New Year's I want to "play" with curves on graphs in Mathcad 14. I am particularly interested in the graphical representation of the Sici spiral (or named after Nielsen). It is represented parameterized in the Cartesian x-y coordinate system by x=Si(t) and y=Ci(t) with t>0. The Si and Ci functions are found in Mathcad on the f(x) menu. But they don't work in the diagram, even though I followed the instructions from the "Help". That's why I didn't attach a test file here. What am I doing wrong?Kind regards, Alfred Flasshaar

Hello,I am Application Specialist at my company.I want to transfer its license to another server.Unfortunately the former license supervisor of our organization at PTC eSupport left the company a year ago.I have two cases, one of them is to ask how to assign the super-administrator or just regular admin role of the organization assigned to his account and its licenses to my account (if necessery, I will confirm somehow, that everything that I am saying is true, just tell me how) I can't access former supervisor's e-mail account.Second case is the cause of the whole situation. One of our servers, started having bugs beyond fixing, unfortunately, this is the one that has mathcad license installed on it. I want to transfer the license to another server but it is assigned to MAC address of the current server, so it won't be working.Can you please help me or give some information, who can I contact to get help that I need, because I can't find any PTCs support mailbox.Best regards
