to all   I am struggling to set up the eigenvalue described in the attached mcad v15 sheet (or pdf). Could someone who understand these things enlighten me?   Thanks Regards

Hi everybodyI have a system of equations with three variables that depend on each other and that are solved by iteration. What I am trying to do is to leave this system of equations in function to the variables ds, Ds and Dliq.To better understand what I want, I have attached an example of what I want to do.In advance thanks for the help.

Greetings dear colleagues of the forum, I am looking for help to solve the non-linear differential equation of second order corresponding to a beam: In this equation:- M is a function that is written in terms of x. This function is variable, it depends on the loads applied to the beam.- E and I are constant values. The first is the modulus of elasticity (E) and the second corresponds to the moment of inertia (I).- v is the unknown that I want to obtain and is written in terms of x. Varies for each beam, same as M, depending on the configuration of applied loads.   I am interested in clearing the deflection "v" that occurs in the beam since I am verifying the results obtained with a structural analysis software called Ftool (https://www.ftool.com.br/Ftool/).   In most books they only present exercises using the previous equation but in its reduced (simplified) version: In this case the solution consists of integrating twice, obtaining: Resolving several cases by hand and

Hello everyone,   I would like to sample a half sine, so I made a conditional function which represents the halve sine. It plots perfectly. However when I try to sample it, it does not work the same anymore as the regular sine function, and therefore I cannot get the DFT. Any Ideas?

Hello .... I have a Student Licence of MathCAD 15.0 at Windows 7. The System where I have installed Mathcad has crashed. How can I  reinstal MatCAD? Further, I want Install Mathcad 15.0 update at Windows 10. I'm thankful for any help. Regards Jurgen

Hello,   Can I have units in contour plot? I mean, i have stress function for example: σ=σ(x,y)   x=[m] y=[m] σ=[MPa]  

Hi, I met a little problem and hope for your help. How to overcome this behavior without manual intervention? MC15 File is attached

I am having issues solving a second order ODE because i need to force 3 boundary conditions, 2 for the starting point and one for the last one. I am forced to do this because otherwise the solution is incorrect so i can just obtain a solution with the correct derivative in 0 or the function with the correct value in 0. Of course if i enable all the three conditions mathcad says to me i have too many initial conditions but the problem is they are equally fundamental to obtain the correct solution. I will attach a picture also. Do you know how can i force a third condition solving a second order ODE? Or in general how to force much more conditions than the ODE order? thanks in advance.

i was working to solve this for submission and now the professor asked to submit it in mathcad 15 format.it is a small file, can someone do the favor please. i am stuck. 

Can someone point me to the user guide to use the NEW API in Mathcad prime 3.1The help system mentions that the user guide is available but does not give a link to it, does not give an online help to it. Also, it seems to implt that you have to pay for teh API!!!!If so this is ridiculous. 3.1 is advertised as having an API as part of its features!!!Can someone shed some light on this?Thanks

Hi, how can I enter the perpendicular sign into a formula?    I've tried following the below instructions but I cant copy the sign into the equation.    https://support.ptc.com/help/mathcad/en/index.html#page/PTC_Mathcad_Help%2Fto_insert_characters_using_the_character_map.html%23wwID0EP3AO    

Hi all! When saving a 25MB mathcad file, Windows creates a temporary file with a name whose first three letters are MFC followed by 4 hexadecimal digits and 0MB size. When the saving is finished, it is automatically deleted. Moreover, if during the saving (which takes several minutes) the operation is disturbed in some way, it happens that the content of the original file is reset and stored in the new MFCXXXX file of the TEMP type, which, then, results unrecoverable. If you open this MFCXXXX file with a text editor, you can access the file. Wanting to recover the file, what are the changes to be made to the opened file with a text editor, and how to change its extension and then save it again with the xmcd extension? Is it possible? Currently I save the files with the name of my liking to which I add the date of the day, so that, if I lose the file, I always have the copy of the previous day. I ask the question in case I want to recover the lost file in the aforementioned way.

Hello Friends,   I am trying to plot something as attached below. Where v2 is a function of v1 and varies according to third variable k. v1 is given by an equation as :   Now as for programming purpose, v1 equation is given as     But when I am trying to solve the equation using root of function k, v1 as for v2, it produce an error that end points of interval must be of opposite signs. Whereas, v2 value can not be in negative as shown in graph above. I have assigned rang from 0 to 4 as mentioned in vertical axis of graph. Can anyone please explain or tell me why I am getting this error and how to solve this problem.   Thanks !!  

Hi everybody,   I have very large scripts (150 pages) in Mathcad 15 and it is sometimes very hard to find the error in the script. Moreover, some calculated values do not influence the rest of the calculations and I might not even notice that there is an error somewhere. Is there a value that I could read out which indicates that an error has occured somewhere in the script? Preferably, I would like to have an indication at the end of the script which shows that no calculation ended in an error. Is that possible?   Thank you for your help!

Dear all, I would like to plot a histogram with text on the x axis. Moreover I would like to perform a calculation without repeating the formula many times. The two points are highlighted in the attached mathcad file. Thank-you very much for your support.   Best Regards.   Enrico

Hi, I'm fairly new to Mathcad. Trying to plot the solution to a differential equation but I can't seem to get it working. I've attached the necessary files.   Thanks!      

Hello! I just installed Mathcad Prime 5 on my computer two days ago and started working on a file. The first two days it was working perfectly, but today when I tried opening the file I got an error message stating that the type of file is not supported. I haven't made any updates since working on the file yesterday. I still need the content of the file and I am also wondering why this happened. I have attached the file. I am new to using Mathcad and I am hoping that someone can help me. (I am working on a MacBook with Windows running via Bootcamp). Thanks in advance!

Hi guys,   my colleagues and I are trying to solve a dynamic problem. We had to plot this graph by using column vectors for each parameter. So each angle (alpha_B; alpha_C, alpha_zyl ) in this plot is shown as a function of alpha_H1.Now we want to figure out how the mathematical function of these plots roughly looks like. Is there any quick operation we can use that shows us how the functions alpha_B (alpha_H1); alpha_C(alpha_H1) and alpha_zyl(alpha_H1) look like?Best regards from Germany!Have a great week! 

Hello,    I really appreciate it if someone can help me to double check the following equation by running my sheet in their Mathcad. I attached my sheet. This time, I use different formula from my previous post here.   In the mean time, I am writing matlab code to double check as well.   I run my sheet, it took so much time with my pc and at the end it show error.   The formula to compute:

Dear All, I'm using Mathcad Prime to solve an electronics problem. I want to calculate the potential difference between node p and n. I have equations for Vp and Vn. However I cannot solve Vp-Vn without having Vp or Vn in the result? In Mathcad 15 this is simply done with "given-find" structure, but this isn't present in Mathcad Prime?
