Mathcad

Hello All, I am attempting to find the percentage deviation of the calculated output.However, in Mathcad Prime, the calculation using matrix indices is producing incorrect results.What could be causing this issue? In the attached screenshot, the output calculation in green font is correct and was done manually, while the output calculation in red font is incorrect and was done using the matrix indices formula.I have attached the .mcdx file with my calculations for your reference.I would greatly appreciate a quick resolution to this problem. Thanks in Advance.   

Solving ode's I have run into this error before: https://community.ptc.com/t5/Mathcad/Return-Value-of-this-function-must-match-the-problem-size/m-p/727295/highlight/true#M195799 I managed to get around it by switching solvers from Radau to BDF, but I still do not know what the message means and changing solvers does not work this time. As shown in the attached (MCAD 11 - converted from MCAD14) worksheet, the denominator of dv does get small but never reaches zero because of the damping factor eta (Increasing eta does help but does not eliminate the problem. and eta should by ~10^{-12} on physical grounds. Setting p0 = 0 in the denominator does eliminate the problem,  although I do not see why. So, it does seem like the denominator is the problem, but, if so, I would have expected to get a "calculation does not converge" message. Tried playing around with other parameters to no avail. Any comments or suggestions would be appreciated.

I am solving an ode. The calculation converges for some parameters but not for others. My problem is I cannot figure out why. There seem to be no obvious causes, e.g. like a denominator going to zero. I have looked at a number of other aspects without success. I am not mathematically adept enough to tease something out analytically, but maybe some one else is. If anyone has any insights or suggestions, I would appreciate it. I have attached a worksheet. It is MathCad 11. I know there are some others out there using legacy versions like me (still using MC14).  Also sometimes instead of the non-converging error message, mc flags the rhs of the ode and says "The return value of this function must match the problem size." What does this mean?

Hey everyone,I’m trying to recreate a Mathcad worksheet from a PDF file titled Shaft Bearing Speed. I’m using the exact same commands from the PDF to write it in my own worksheet, but I’m running into multiple errors and mistakes that I can't seem to understand.I’ve attached both the original PDF, my Mathcad worksheet, and error screenshots for reference. I’d really appreciate any help in figuring out where I might be going wrong. Thanks in advance. Below are the screenshots of my errors... PS: The excel component is in-active in my worksheet for god knows the reason & hence, I had to use an image there, but with a "Read Excel" command on top. I hope you don`t judge me on that... 

Hey everyone,I've been working with Mathcad Prime 10 for a couple of months now, and I recently came across something that has me stuck. I’ve tried searching for a solution in multiple ways but haven’t been able to figure it out.In the equation I’m working with (in reference to the attached image), there is a right-facing arrow above the expression: concat( num2str( d/mm ), "mm" )I’d like to understand what this operator is called, it`s function, and how to insert it in Mathcad Prime 10. Any insights or guidance would be greatly appreciated! — Srikar

Hello,I have just started using Mathcad Prime 10.Does Explicit work with min and max functions, or I am doing something wrong?Please see below example screenshot. I'm sorry but I cannot attach the full example as it is too big and it is work related.I get "The unit are not compatible" error. GSKID is an Output expression from an excel component.Bs is extracted from a matrix. I have turned on Units/Constants in Symbols   

 

Hello,How to fill the below area enclosed between y1(x), y2(x), y3(x), and y4(x), like below with purple?          

Hi Mathcad Community, I’m working on a problem involving a box cross-section. I need to plot the shear flow distribution q(y) along the height (y). The plot should be linear in the flanges and parabolic in the webs, but my current plot is a step function and doesn’t match the expected values. Can someone help me redefine q(y), and provide the correct Mathcad function to plot a continuous shear flow distribution?Thanks for your help! 

I want to present results in a table I created.But having the variable name showing when I want to display the results is really not convenient.Anyway around that other than hiding the name with a white box? I mean...It's Mathcad...  Not Paint... Thanks

I have tried transferring my license to a new host ID. I accidentally transferred the license to an old host. When I tried again, I received this notification "Thank you for using Mathcad. You have reached the maximum number of license requests available for your product type. To upgrade to the latest version of Mathcad, please visit store.ptc.com"  Then, I emailed the lady that I worked with to get the license. She referred me to a Access Enablement & Distribution Senior, who forwarded my email to a couple of peers and ultimately said "Since you already have the product code for Mathcad, we recommend you to try to move your product using the steps listed here: Transferring Mathcad Single User or Student lice... - PTC Community Mathcad Educational Users are not supported by Access Enablement department therefore we suggest you to use the Mathcad Community page for further details: Mathcad - PTC Community Thank you for understanding. Have a nice day!"&n

Good Afternoon Community, Need some help with solve block with Find function. Please see attached. Thanks, Boyer  

where can i found the product code, there's no message entry from my email 

Hello,I purchased an upgrade to Mathcad 14.0 some years ago (2013, personal purchase, not a company). I installed the software on my PC at the time. In about 2017 I purchased a new PC and never installed Mathcad on it as I did not need it then.I now live at a different address, have a different landline phone number and a different PC (compared to 2013). I have just tried to install Mathcad 14.0 and the software installed OK, but it cannot connect to the license. I have reset my password and have been able to log onto the PTC site to send this message, but I cannot get Mathcad working.Can you advise on how I can resolve this issue?Regards,KH.

Cannot reactivate license after computer repair. Hardrive replaced

When I try to 'Activate' my license in Mathcad (from Mathcad Express), it asks for my Product Code. Other 'Help' solutions pointed to the confirmation email, which mine does not contain the product code. Also, a link was provided to another site, but that site is in 'Maintenance'. Is there another way to find my product code?  

I received a license to use while the estore was down from a representative, but it only worked when connected to the wifi I set it up with. Now I purchased the mathcad student prime version, but still, it only works with whatever wifi I am connected to when I set it up and get only express version everywhere else. Is there a way to fix this? I paid for the license and need to be able to use it in different settings.

So, recently Mathcad wouldn;t open, I deleted it, then installed again but this time changed the file location. Now, I can't open any worksheet, if I don't go in the app, Open, and then select the worksheeet. Also, the worksheet in the activity bar or its location doesn't show the Mathcad icon. What can I do to fix this problem?

hello everyone, let's see if you can help me. It turns out that I want to plot a root locus.It turns out that I have to solve the equation [1+ K G(s)* H(s)= 0] for each K.For a given K I can do it with solve: for example:G(s):=10/(s^2+2*s+10) and H(s):=5/(s+5) for a k:=3 gives me the following result.R:[-7.75;0.375-5.07i;0.375+5.07i]how do I get the same within a program by varying k by different values? 

Hello!I'm unable to upgrade my account (using https://support.ptc.com/appserver/common/account/secure/premiumAccount.jsp page) to manage my Mathcad license.I can not activate the product or get the activation file.I can not open even a ticket to support.

I recently learned about the following problem, whose solution function u(t) requires determining:u´(t) = -u(t)/t + 1/(t^3+t), u(0) = 0I intentionally called this problem a riddle 😉 .Please answer in MC14-readable format.

Hi,I have an equation likeWhere Q(x) is some complicated complex function of x. This way f (or sol, if you prefer) is a function of x.I would like to make x a range so that I can plot f as a function of this range.Is it possible to do that?Thanks  

I have an array (numbers of rows - 1,  number of columns - can be different). Example: I enter a variable in mathcad d = [1 5 10 15] and i want this array to be displayed in my list as d = 1   d= 5 etc... Help please. Preferably in JS. Translated using Google Translate.
