Mathcad

i Mathcad experts,I have some questions about Mathcad function. I don’t have any useful idea to solve my issues.I have one equation, and I can draw the curve of this equation.And then I try to solve the peak value of curve (fig.1) by using the method in EX2.Below are my questions.1.Any method I can solve this equation to get the fn_Y2, please see EX1?2.How do I use solve function to get the fn_Y2, if I have different inputs Q2 at the same time (please see EX3).  I can do this when I only have one input, please see EX2.3.If the issue 2 can be solved, and then I would try to input the fn_Y2 to get the peak value . Also I would like to draw the relationship of Q and peak value, please see the fig.2 (this fig is from TI’s datasheet), could you please give me some suggestions.

Hi everyone,   I have a problem with interpolating data in Mathcad. Please see the attached file. In Excel, I have defined materials and temperatures. I want to replicate this in Mathcad so that when I select the material and temperature, the corresponding stress value is automatically displayed. Additionally, for temperatures ranging from 100 to 250, if I select a temperature like 120, the stress value should be determined through interpolation based on the material and temperature.   I have also attached my Mathcad file. I approached this in two ways: The first method works for standard temperatures like 100 and 150 but shows an error if I select a temperature like 120 that is not explicitly defined. The second method involves interpolation but only for one material. If I have multiple materials, I have to repeat the process for each one.   If anyone has encountered and solved this issue before, please let me know.   note - these materials and temperatures ar

Hi,I am new with mathcad, Could somebody help solve problem. Why temperature value is marked red color?

Hello everyone  I worked on MathCad 13 for years, but recently switched to MathCad 14. Generally, both versions are very similar, but it turned out that I have a problem - MathCad 14 is not able to solve some equations using the "solve" function, which version 13 solved. After a few seconds of "struggle", an error message appears, as in the attached graphic. In turn, in cases where version 14 solves equations created in version 13, it does it very slowly - in version 13 they were solved immediately after opening the file, and in version 14 you have to wait a long time, even about 10 seconds. What is the problem and how to solve it? I would like to mention that I cannot return to version 13, which I would like to do. Thanks

In mathCAD prime 10, how to do element product in two column vectors? For example, A := [1 2 3]B :=[4 5 6] I want to have C=[4 10 18]. In this case, how can I express it in mathCAD?Please help me!

Im having trouble transferring my calculations from my private Computer  ( PTC Mathcad 10 version trial) , to my university Computer (Version 9)Directly opening the new version Files, on old version is ofcourse not possibleCopy Pasting it in a external document and inserting it in the old version also does not workMy Question is, Is there any way of transferring my calculations from new to old version ?(It is not posible to make any aditional Instalations on Uni Computer) 

I have defined function with "for loop" inside for table content processing. It looks simple, but unfortunately it doesn't work. Instead of calculation results , the message  "This value mus be a scalar a matrix" is being displayed.I was using this function with Mathacad 15 and it was working fine, but I can't reproduce it within Mathcad Prime 8.Where did I go wrong? Regards,Bogdan

I am trying to get a pressure-enthalpy diagram for methane by using Coolprop but I am constantly getting Pressure_out_of_range error. Does anyone know the solution?

Hi all I am having problems with PTC Mathcad Prime versions. I use the latest version, i.e. 10, but colleagues etc. use varying versions, for example 9, 8 and 7.  However, they do not have the option to upgrade to the latest version. When I send them the file saved with the latest version, they can't open it. What is the solution? The best would be a solution where I can save the file so that it can be opened in any version, because I don't always know which version the other party is using.

Hi,

Hi,How to solve for V2(t)?

I recently encountered a really strange programming error in MCD11. A calculation of the sum of three terms only includes the first two; the third term seems to be ignored. When the calculation is simply repeated, in what should be a second identical calculation , replacing the result with the (supposedly identical) new result, the repeat calc now gives the correct answer. The program is a simple transmission line simulator, which I was originally running with 1000 time points and 100 spatial points along the T-line. I was able to keep the error behavior using 6 time points and 4 spatial points. The attached program and pdf show the behavior. Referring to the pdf, on page 1 is the original program on the left (with the error) and the modified program (that works) on the right. The only difference is the repeat of the calculation line for vn(kt,Nline). This term is the sum of three other terms – as shown. I spent a lot of time troubleshooting the program when I realized it was

Hi,This is a modified variant of this circuit from this topic.As I am interested why odesolve block cannot solve such a kind of circuit or why we cannot use odesolve block here... let's see if someone will come with an answer by solving this problem using odesolve block.Find the current through C1, voltage across L1 and voltage across R3. Analysis must be done using odesolve block.   a) Vs(t) = 10V   b)  

Hello,  I am trying to utilize the new advanced controls textbox functionality by changing the background color of the textbox based on the input condition.  The input condition would be a defined variable called "Ratio" and whether or not it is above or below 1. The textbox would be assigned to the variable "Check", if Ratio is above 1 than check would read "No Good" with a red background, If Ratio is above 1 than check would read "OK" with a green background.  I have been searching through previous posts and had some help but am getting stuck with what appears to be passing in input variable "Ratio". I keep getting the following error. I have put the file I am working on below for reference.  

Hi there, Is there any way to insert data from PDF or Notepad into mathcad without the need to change the file into excel. I tried to do so by copying past the data but I got my data as text , couldn't past them into a matrice or table 

I have six matrics of z values and I need to apply this formulae in each one of them . I tried many programs like the ones I used before, they didn't work . Can you please help me?I also stuck in the same problem everytime can you also give me hints to solve these issues in the future.Thanks in advance

Hi,Find the current through C1, voltage across L1 and voltage across R3. Analysis must be done using odesolve block (but of course other methods are welcome).  

Hi,I have this signal formed by a vector data points: And I want to make the  blue signal (a) to look like more green signal interposed on the blue signal:   Is it possible to do something like that from the a vector data points?Idea is that I want to have straight lines also on this portions of waveform:
