Hello,   I am doing this exercise about a combined cycle where some of the enthalpies are known.  The problem is when i try to solve the system the error "This variable is undefined" constantly appears. I have tried both of the systems i know about describing the solution:     Solution:=Find(x1,...) and (x)                                        (y)  :=Find(x1,...)   Hope there is solution. Thanks in advance. IG88   (Uploaded the .xmcd)  

Hi, Our service contract expired and I am trying to download 15 M030 but PTC does not allow it. What is the procedure to obtain the link? Thanks  

All, I did install the German version for Mathcad 15 M050. Starting the application I can only choose the English language. The German language is not present in the list to select in Tools>Preferences>Languages.

Dear all please create automatically Global Stiffness 6x6? as pic and attachment mathcad belowThank you  

From my (very limited) experience, in the (if, while) loop, Mathcad doesn't allow := but only <-. I was just wondering how are they differ from one another.   Thank you!

Hi All- I am attempting to model the first-order change of A --> B. The little programming loop below does the transformation of A to B in time steps of n just fine. The problem is I cannot view the A vs time data as is shown in the MathCAD document below. I know there are many other ways to solve this simple system, but getting this little programming loop to solve the problem is my goal.

Is there a way to fix this? I have a single-very large size of matrix(10 pages) and when I do anything within this matrix, it will start lagging.

How use Celsius here? Thanks!

I would like to create the digital double of  the yo-yo toy Were is my error? See please attachs MC15 & Prime 5. Do you know someone? Thank you!

I would like to calculate multiple values under one if statement. Right now, the only thing I know about if statement is that I have to assign if statement to a variable and that means I can only do one variable at a time. Please see below. For this example, if I would also like to compute some other variables other than SF under condition that d<=1/4 in, without creating another if statement, what can I do?   Thank you very much!   Edit: clarify question

Hello All, I am generating values for DEFORM FEA software to determine a sinusoidal motion. My current method is to develop the function for my motion in Mathcad, then take the variable value and transplant it into Excel.  From Excel I can copy and paste into my DEFORM table. I would like grab the values directly from Mathcad. Any suggestions would be appreciated! Thanks, Don

I am new to MathCAD and the following is what I would like to achieve. Would someone able to help me with this.      

Hi everybody! Is there anyone who can tell me what to do (or how to avoid the error) when, (MATHCAD 14 S. E.) with automatic calculation disabled, while saving, appears: "A generic error occurred in GDI +" and I can no longer save the file?

What I'm trying to do is, I have a data for aluminum properties(shown below) where I want to be able to input/select alloy type, temper, and product for that alloy. Then I would like to be able to get the properties of that selected metal. This topic (their Mathcad looks very different from mine, idk why) have asked the same thing that I want(although, I have 3 inputs, while this topic has only one input) but the problem is that couldn't follow the steps in there and am completely lost.   I'm very new to Mathcad and my Mathcad doesn't have any add-on(if that's needed), please let know what I need to do if I have to.   Thank you very much!

Hello! I'm having trouble using the maximize function for 4 variables that I need to optimize. I'm using Solve Block, all the variables are defined and even then it hasn't worked.I'm sending the file in case someone can please help me.Thank you!

I have a lot of difficulties formatting documents in Mathcad Prime 6.0 in relation to hard page breaks, and I wondered if anone else had similar problems and/or solutions.   I find that when I have page breaks in a document that regions can cross over hard page breaks. This can happen when you are editing in the document below where the page break is inserted. If you start at the top of a document and work through it, inserting page breaks and re-arranging regions as you go to get a well-structured document, when you go back to the top, you fing that everything is rearranged. Regions that were below the hard page breaks are now above, and there are large blank areas, or even pages. It also happens that the rearrangement can happen between a close and open. Very frustrating. Any suggestions?

Hi, can anynone help me please?!   I'm trying to solve this sistem of two couple differential equations but I'm not getting sucess. (I guess that the error is in the red highlighted in the second equation)

I don't want to display the result as fraction. I also changed the default to decimal but it doesn't affect. When i click it there is no result format that could be change. Someone have idea? (file attached below)  

Hi,   I am prepare spreadsheet for composite coating density, but I was tried to get result in to table format and no successful. So, I need help from all of you to put advise/solve problem.     Appreciate your help.   Aries 

Mathcad 15 - an error. Prime 5 - a constant not function as an answer! See the attach and help me please!  

Hi,   I have a case in below snapshot is an extract of pipeline end expansion Mathcad spreadsheet calculation for determining the cold anchor point location highlighted in yellow. However for certain combination of input data, the calculated cold end anchor point location does not give the correction solution using the solver function when there are more than one intersection points at the cold end of pipeline as shown in the graph beside. Please can you help with a solution where the solver function for calculation of the cold end anchor location will output only the intersection point closest to the pipeline end.    

Hello!   I am trying to plot the picewise function (attached). Do I need to use "if" statement here or are there any other options? I think that it should be something like this: if 0<x<0.3 then y=2, if 0.3<x<0.8 then y=-((x-0.3)/0.5)+2, if 0.8<x<1 then y=1. Would anybody, please, help me with this issue?   Best regards, Sergey

Hi PTC Community,   I would like to find a solution and better understand of how I can define this type of equation and how to get the results for the arch height at different points. I am attaching a sketch for a better understanding.   I thank you all!
