Mathcad

Hi!   While using Mathcad Prime 6, I encountered a rather strange error. When I try to find solutions to an equation using solve, Mathcad says "Unknown error: "failed"_of_mode_Union". I have done the same procedure a couple times before, and it worked every time. I don't think there's a problem in my code. All the units check out. If anyone could help me solve the problem or recommend a way to get around this method somehow, I would appreciate it very much. I tried solve block, but it only gives one solution and I know there are multiple. I attached the mathcad code.   Thank you in advance!   Sándor Herőczi

Hello,I just stumbled upon the weird fact that for Prime1 certain sums are not absolutely correct. For example, Prime1 calculates1.4 + 0.2 = 1.6So far, so good.But if I check if (1.4+0.2) is the same as 1.6, Prime1 tells me it is NOT!When I create the difference it gives out1.4 + 0.2 - 1.6 = 2.22*10^-16which is almost correct but just not correct enough!In the case of1.2 + 0.4 = 1.6Prime1 works correctly.Please see the attached Prime1-sheet for further examples.Is this a common error with any calculation software or is this just mathcad?Is there a way to avoid this error?Best regardsSebastian

Dear AllI try to use 'Cache Worksheet', I noticed that when I open another computers without Original Path it still work well.My question is ,for confident future using (my sheet), How program store that Original Path/Formula in Original Path?Thank you  

I am student at Politehnica Bucharest and cant use free student mathcad

Can anybody help me recovering this mathcad file? It wont open.

What I want to do is move Mathcad 14 from my old computer to new computer AND license it. When I try to use the Mathcad License setup on my old computer, and enter my product code (JG140702EU3136 PHT4 CY4H), log in to my account (under my current e-mail, erinpreciouscat@gmail.com), the wizard starts contacting the PTC licensing server, but gets an "Unexpected Error" window saying "The server committed a protocol violation. Section=ResponseHeader Detail=CR must be followed by LF." So long story short Mathcad 14 won't run on my old machine and I want a working version on my new machine (no longer need it on my old machine).

Hi Everyone,   I found a website that says it sells a Mathcad software with product key.   How can I make sure if it really sells an actual license?   Note: When I asked the support of the website, I was told that they provide full software versions with a product key (built-in product key in some cases) and OEM activator. And that the only difference is that it can't be registered online and I can't get support from the vendor.   Thanks in advance.

The error message says the number of fitting parameters and guess values must be the same, but they do !!! Please, take a look to the file attached, this is a short programm.

One of the features from Mathcad 15 that I miss (occasionally) is the ability to display a histogram of a vector of data--the ability to display the general shape of a distributed variable is valuable.   Prime (at least Express, where I'm stuck) doesn't have that feature.  Being bored to tears with the pandemic, I set out this morning the be able to take a vector of data (of random length) and develop a histogram of that data.  (A histogram, for those not familiar, divides a range of values into a set of discrete "bins" and returns the count of values in each bin.)   I was partially successful.  The attached Prime 4.0 file demonstrates the technique.  It also demonstrates several issues that I'm hoping someone smarter than I can help me with.

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

Hello Everyone,   I am wondering if there is a way to assign units to a web control list box/combo box?  I have a list of steel plate thicknesses which I want the user to select and I want the units for these thicknesses to be in inches.  When create the list box it doesn't appear that I can embed the units in the selections as when I try and do that it makes them text strings.  It also doesn't appear that I can add units after the list box either.  I know that just create another variable where I multiply the value from the list box variable by the proper units but I was hoping to not have to do that.  Is there something I am missing?  Thanks!  

All,   Is there a way in Symbolic Analysis where the collect function "collect,s" only collects the s terms but does not distribute our the variable? The equation becomes too high entropy with distribution   Please see attached   Thanks Rdliquid

Hi everyone,As you can see in the picture below, MathCAD 15 has the worksheet grayed out. I can't figure out how to fix it. I can still enter data in but I can't read any of it because the gray overpowers the text color.Any ideas on how I can fix this?Thanks!

Dear allI wonder this tab "Show As List"? what use for?Thank you  

Do you know involutes of n orders? Can you plot it in Mathcad?    

When using the WriteCSV() function At what point does mathcad actually write the file? When you close the program Periodically?    How do you force it to update the CSV file?   Thanks in advance 

Hello, In the attached sheet: For each load value for P, i 'd like to compute von Mises stress when the load is applied at different angles provided the von Mises stress doesnt exceed the limit( 50 ksi).  it should report each load, the angles, and von Mises. if the stress goes over the limit then not to report the angles or the stress because it exceeds the limit.   Thanks, Sam

Hello. I'm currently doing some basic unbalanced 3 phase load calculation with complex numbers. I decided to use a matrix for this purpose. Any suggestions for a faster and better way to find the phasor angles WITHOUT the added +30 deg. vector angles between phase and line voltage.   Thanks!    

To all, Forgot how to do the following in mcad 15 I’d like to find the “best” possible (feasible) set of numbers (variables) to minimize an error. See attached I am sure I have seen examples about similar problem but can’t find them right now. I'll start looking at setting up the problem but I thought I'll ask in the meantime Does one have to set up a Given (Find) block with the possible equation(s)/inequation(s) or should a function be defined Thanks Regards

Habe mir auf einem neuen Computer MathCAD Prime 6 heruntergeladen über Ihre Webseite, eine neue Lizenz angefordert und bekommen, wollte diese aktivieren, jedoch bekomme ich ständig folgende Fehlermeldung:20.11.2020 11:52:04 : Die Lizenzanfrage ist fehlgeschlagen.Requesting MATHCAD ...C:\Users\Gernot\Desktop\sw_license_email_4975412.dat\sw_license_email_4975412.dat: (-21) License file does not support this versionLetztendlich wird dann Prime nicht aktiviert.

Hello Everyone.From : How to plot a cup ? Thanks in advance for your time and help.Regards.  

I bought PTC Mathcad Prime 6.0 Student Edition – One Year Term License and I am trying to download PTC MathCad 15.0 and When on the Mathcad License Setup page on PTC mathcad version 15.0, when it says to enter my account information it will not accept my username and password but I can sign in on my account directly online on www.ptc.com like it says in the error message. Please Fix

Bonjour, j'aurais besoin de mathcad 15. J'ai utilisé l'essai de 30 jours, maintenant j'aimerais savoir combien avoir le coût pour installer matcahd 15. Merci!

I am trying to build circle Involvents. I built five involutes, and the sixth, the seventh, etc. there is not enough time and power of the computer - see attachment Prime 6. I will be very grateful if you can give me a way to make my work.

Lets say I have 55kg   I want to get the equivalent in Stones. How can I set this up?
