Mathcad

I am using an include statement to include calculations and values from a reference sheet in my main Mathcad document. Is there a way to get access to variables defined in the parent document in the reference document? For example, if I define a variable called "mass" in the parent document, and then I have an expression in the referenced document that multiplies mass by 2, as in: double_mass := mass * 2, will that work?  Right now, I am only able to use variables in the reference sheet that have been defined in that sheet. I do note that functions and variables defined in the reference sheet are available in the parent sheet following the include statement, as expected.

Hi folks, I'm looking to do some quaternion rotations, and wondering if anyone has anything set up for this in Mathcad prime? Seen some posts that have it in regular Mathcad but can't manage to get them to work when converted.  Thanks in advance,Stuart

Hello, I can't solve my problem. I opened a programming block and inserted a matrix to make it faster instead of clearing equation by equation. The values I want to have are A_x and so on. I give M as input data. Help

The attached MC14 file is looking for a limit. The result should be -pi^2/8. My attempts failed. Only with the help of good old derive did I manage it. How does this work in MC14?

I m a student and i receive on email a sw_license_email.dat for mathcad but it does work

I had a copy of Mathcad Express on a computer got infected and we had to wipe the drive. I use it to read and review Mathcad files. I would like to download it again on my new computer, but when I go in and try to do that the system wont let me download it again. What do I need to do?

Hello All,It's just me with one thing after another. And now my trial version of 10.00 don't work.I get an error message its attached.It's about a file edidebug.dll which is not seen as friendly by Wins 11 smart Protection!PTC and MS got conflicts!So, anyone who knows about this please enlighten me before I start believing in conspiracies and paranoia, Thanks. Regards,Karl.

I am using Mathcad Express 10 to calculate the stress and deflection of components under a specific load case. To avoid having to create a copy of the calculation for each component, I want to perform the calculation using vectors and matrices simultaneously for all components and their values.Unfortunately, I don't have access to the full version of Mathcad so I can't use any programming.However, when I switch the calculation to vectors, a problem occurs that I cannot solve. I have created a minimal example, see attached file.There are three vectors (v1 - v3) which all have the same length. The length of the vectors results from the number of different components to be calculated and is not fixed but can change. Therefore, the solution must work with any vector length.What I am trying to achieve: I need the maximum values of each line from the vectors for the calculation later on. The resulting vector then has the maximum value from all the first rows of the vectors in its row 1 and s

Hello, I'm working in Mathcad Prime 10 I am struggling to get a solve block working. I'm attempting to calculate a grid convergence index based on a published guidance document, and it requires an iterative approach which I thought could be executed by a solve block. I'm receiving various errors (see one in the image below) depending on what I try. I have attached my current workbook. Thanks for any help you can provide.  

I have downloaded (twice) the Mathcad 10 for the suggested Host ID and Mathcad still states:License Status: Invalid & License Type: No License and when Mathcad is opened Çreated with PTC Mathcad Express'.Please note I have a ''PTC Mathcad 15 Student Edition – Perpetual License'which came with Mathcad Prime 3.1. I am unsure where i could download Mathcad 15 and the only option appears to download Mathcad Prime 10.Any advice how I can get any version of Mathcad up and running would be greatly appreciated..RegardsDave

Buenas noches comunidad, tengo un problema en una interpolación. lo que estoy bucando es encontrar un Q que sea constante (interpolación). Gracias por la atención. Version de Mathcad Prime 9.00 

The installation process will inexplicably stop in the third step, making it impossible to select the product to be installed.

  Hello Everyone, From:   How to Fill Surface the Blue Curve ?   Thanks in advance for your time and help.   Regards.

Hi, I am creating a calculation report in Mathcad Prime 9 and I was wondering if it's possible to create a cover page that would not have the header that the rest of the document has. So far, I have not succeeded therefore your help is more than welcome! ThanksRegards,Alex

ich habe eine lizenz und will es auf einem anderen gerät installieren aber da steht lizenz bereits erworben

Helloi have an equation. lets saybut if i have less arguments i want to do a different operation, lets say:(of course defining the expression like this will say that it was already previously defined)I dont want to create a new equation with different name.   how can I modify my original equation to understand that the missing argument is null  the closest i have reached is using an IF operator and checking if the other arguments are 0something likeif z = 0 and y = 0     return xif z = 0     return x * yelse     return x * y * z then I need to wrinte something like this --> F(5, 5, 0)if the ecuation is more complex i dont want to write 0 on the argument i would like just to writeF(5, 5) and the equation should understand that Z is missing so just do x * y hope you could help me  

Hello  Is there a way to get shown a the formula behind a value. For example: If i define value for "e" = ((250/2)-(250/3)) = 41,67 is there a way to show the formula when later in the dokument i want to use the value "e", but i want to show how it was determined? when i try to show it now it only shows e = 41,67? best regards AJ

HiI have tried to create a program that calculates a function for each value in the vector, but the result is not being saved for each loop. What am I doing wrong? Thanks for your help.   

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
