Mathcad

  Hello,   I was able (with some help from the community 🙂 to solve a single ODE using a MathCAD 5.0 Solve Block but now I want to solve a system of 3 ODE's but I am getting an error (see attached file).   I suspect I am making some newbie error. If someone can enlighten me as to what that error is and tell me how to do the calculation correctly, it would be much appreciated.   TIA,   --Doug  

On the MCad15 version I used to use Combobox (Microsoft form component) linked to Excel to feed the control as database.I have noticed that Prime 7 has its own Combobox with some limited input options and does not allow import MSforms as object.Does anybody has any recommendation for this topic or it's something that could be included in new releases?Thanks in advance

This seems to be a bug.  Prime 7 won't plot degree C or F on the x-axis of a plot.  (Kelvin and Rankine work fine).  And degree C/F seem to work fine on the y-axis.  (I know degrees are technically functions and not units in mathcad, but this worked in version 4.  )  Is this a bug or a quirk?  any workaround (besides using absolute temp - which isn't very practical)     Prime 4 file attached.  open in 5-7 and refresh and you should see the error.     Thanks,

Is Mathcad compatible with Windows 11? I have tried a couple of Windows 11 PC's and can't get the install to launch. Is there something special we need to do?

How do I get Mathcad 15 trial ?Where do I find Mathcad 15_EN.zip ?

How do you create dot variables? One dot on top of the variable indicates first derivative, two dots, the second derivative. I'm using Mathcad Prime 8.0.0.0.Thanks!Jack SmithKaty, TX

Hello!Is there a way to change the inline division sign from this "÷" to that "/" ?I saw arguments about the slash sign can be misread to 1, but as is the division sign can be misread to +.It would be great to be able to change the operator styles as we please.Or can I find the files where the operator characters are stored, so I could override them manually?P.m. Im using Prime version. The goal is to be able to see the following: x/y, and not x÷y.

We installed MathCad Prime v8 on a client system. I will not connect to the license server. Do we need to upgrade the license service on the server to run V8.0?

I am trying to install Mathcad Prime on a new PC. I have entered my information twice on the PTC website but I have not yet received an email with the installation file.

Hi. I have been encountering some odd issues while copying expressions and eqautions in Mathcad Prime.It would seem that everytime I copy an expression containing a variable it doesnt fully understand how to work with it afterwards.This has been accouring both on Mathcad Prime 6 and 7. Its quite hard to explain and show for that matter. But let say that I define a function f(x)=23x. If I were to copy this expression from and, let say differentiate it, and afterwards create an equation from the output, it would be unable to understand x, as if x now has another meaning.  This works fine if I abstain from copying the expressions and instead write them manually. I have attached a small expample of this happening as a PNG. I have failed to find a solution myself, but I have a slight feeling that it might be because of the PC that Im using.

Hello! There is something wrong with the plot of the function (look at the attached file).When "x" is defined from 0 to 10 the plot looks correct. But when I define "x" from -10 to 10 plot looks like a straight line.Where did I make a mistake during the plot? Best regards,Sergey

Is it possible to use colan (:) symbol in literal subscripts for defining variable in Mathcad Prime directly ?  

You may have some insight regarding an issue I have experienced with both Windows 8 an10 with MCAD15-050. decoupling taskbar items such as the "calculator".  When I do so  by selecting with the left mouse button, there is an empty context box that is offset from the mouse location. This box moves with the mouse but  the location of the "calculator" context window is where the mouse is positioned when the left mouse button is released.

Hey I'm having trouble with the shortcut for vectorization. It says to press ''Ctrl+Shift+^'', but how do i press ''^'', when I press the bottom whit ^¨~ on, it puts ''CONTINUE'' in... i I have tried to press ''Ctrl+Shift+alt+94'', and it does not work either. hope some have a solution to my problem.

HiCould someone please convert the attached MC15  file to Prime 8 and advise if the drop down list works in Prime 8Thank you. 

 

I have a few engineers testing out Mathcad. They're working on Workspot (Virtual machine) and are getting an error when attempting to license.Cannot checkout an uncounted license within a Windows Terminal Service guest session.Workspot is not remote desktop... Thoughts?

Hi,I'm wondering how to upgrade to MathCAD 8.  Thanks, -DS

Good night, I'm having problems when performing calculations with complex numbers, the application is returning wrong values ​​for division operations with complex numbers

Hi there- these two files are not passing through the converter. I have absolutely no idea why. I have tried removing the plot and plotting function from the soil force mathcad15 sheet but that had no impact on the conversion and its still failing. Any and all help is appreciated.

We are retiring our Windows Server 2012.  I have the license manager setup on the new server but need a new license file. Where do I go to request a new license file for that server and Host ID?

I am on a Honeywell support team and a user cannot get a license for MathCad 15 after putting in the license and port info. Other users have a license. Our local help desk cannot figure out the issue on his local machine. The license server has been checked. We are out of options to help this user get his work done. I should add that other users have had this issue but it is resolved by entering the server and port information. That has worked in the past for this user as well but not this time.  Also, in the past it started working for him after a few days without changing anything.  

I have a set of 4 equations which are used to determine the relation between Bèta and Delta_L.Now I have to generate a list of values for alpha and through x2' and beta + y2' I am able to calculate Delta_L. For any value of Delta_L I then need to interpolate to get to the approximate solution. I would however prefer to have a direct correlation between Delta_L and Bèta without alpha (if possible of course). Thought the symbolic engine might be able to help but to be honest it's been a while since I last used it so I'm stuck. I have attached the formulas in the attached calculation sheet. Any help is kindly appreciated. 

Hello all, I am having a bit of an announce with my header/footer in Prime 7.0.0. I have embedded the file name in the footer of my routines. Every time I open the routine the text block containing the file name 'resets' to a single line and part is not visible on the printed page. Is there a way to lock the text block to prevent this from occurring? It is not major but having to re-size the block every single time is annoying.  Thanks in advance for the help
