Mathcad

Hi, I worked on this file and all of a sudden just crashed. Now when I try to open the file it says that "The file type is not supported".  Is there any chance you can recover it?

Hello Dear Friends,   Is there anyone who has already some Mathcad 15 files on the subject: Transformers and Inductors Design? And therefore can share them with us? Thank you. Best regards.

Hi,   I want to find the accumulative sum of the hysteresis loops. I wonder how can I do that?  

I want to put the result in a variable f.1(x), but the mathcad says that this variable is undefined. The only way that works is to assign by-hand (as seen below) but i would like to know about more clever solution  

I can't install the license

i have used mathcad since last year. all was doing fine. since yesterday i had a "Breakdown" if you call it so, i wanted to start the program at school and it didnt start at all! i deinstalled mathcad and reinstalled it using a new lisencenumber, since that is the first that came into mind, but no, it still does not open the programm! i need it for my technical classes. its very urgent! how can i repair it if something is going on wrong?!!thank you!Regards M

  Hello Everyone.   From : How to plot a conical hat ? Thanks in advance for your time and help.   Regards.

Hello,   Attached is a little program that calculates the normal and shear stresses. Load P can be applied at different angles. I'd like it to report the results for the loads, angles and von Mises stress. I can't get it to run. I am also wondering if i can include the units for area, section modulus, load......   Thanks, Sam

Hello all,I am planning to buy Mathcad 15 full version through my university.Could you please suggest me some links to buymathcad 15 to use it in the university?Thanks.

  Hello everyone.   From :   Many thanks for your time and help in advance.       Best Regards.            Loi.

Hi, I am trying to simulate a base excitation using a velocity versus time waveform as the base excitation. I have imported an excel file and developed a velocity time function using "linterp". When I try to integrate this it flags an error. Further down the sheet I use an indefinite integral to derive the base input displacement from my velocity waveform. Is this OK. Any assistance would be appreciated. Cheers Ross

hello,   I'm curious if we able to do sum of square in mathcad? I'm thinking to the the sum of square on math cad for the filtered temperature and unfiltered temperature. Scenario 4 & 5.    if it is impossible to do it on mathcad, would you please recommend me the way to download the data to excel?   Thank you so much

Hi team,I am not able to find the average of a function. Can you please help.     TIA

Dear AllI am stuck here. I can not find any method to solve the solution of function like below, help me. The goal of this sheet to find solution X and we have function and many variable. And variable will input below.If you have any methods to solve this problem please.Big thank. 1.Function 2.Data Input (below function)    

Hi,PFA the MATHCAD file. My program on page 13 is not working. Can you please help me.TIA

Hello, in the scenario 5, I will need to do Tfi = alpha*Tn+(1-alpha)*Tf(i-1). which mean the new Tf value  at time (i- 1). I'm not sure how to have that i-1 here in MathCad. Tn is calculated in scenario I used i-1 vector subscript but it seems doesn't work I really appreciate if you can help me to take a look this. Thank you so much!

Hello everyone,  In scenario 4, I got everything correctly. However, when I tried to graph the plot. There were an issue with "too many range variables".    I read some posts that recommend to change the number of points. However, it was invisible to click on. Would you guys please help me with this?   Thank you so much

Hello everyone,   I will need to generate the value for x using the time frame. x is in (0-1). I know mathcad 13 has seed function, I tried that on prime and it doesn't work. Would you please help me to with the function?.   That is the scenario 4 if you want to take a look 🙂 thank you so much everyone again. I also attached the sheet I create for step by step

Hi everyone, I did this project on Matlab so I'm not sure how it should be at MathCAD. I have 1 condition   Td(t) = if(t<theta,To,T*(t-theta).   My professor got the result from MathCAD, I'm not sure how do we use if function here?   I also attached the file in this post, the issue was occur at scenario 3.   Thank you so much again,  

Hello Dear Friends,What are your reasons for which do you want to stay with Mathcad and not to migrate to other mathematics software (like Matlab, Maple, Wolfram Mathematica, etc)?How do you feel when you are aware that another mathematics software offers or has more facilities in many things than Mathcad?I think you've been with Mathcad for a long time, and therefore if you want to switch to other math software, the learning curve for that software isn't that easy (due to the fact that math software has generally evolved a lot, it is very complex in nowadays) .. and then there is this restraint for Mathcad.. because do you know a lot of things of "how to do" in this software.What are your opinions?Thank you.Best regards.

Hi all, I am trying to read several .dat files from a certain folder by specifying the path in Mathcad 15. I wonder if there is any script function to do that instead of inserting all the files one by one?

Hi!I'm trying to write a small program that calculates a new force for each increment. Each force will calculate the von mises stress at different angles . Edit:My desired output is the force (for each increment), von mises stress and corresponding angle just before the yield criterion.  (see file)Not sure how to finish off my program. Regards Sigurd   Thank you! ps.Mathcad 2014

Can you create this "square cardioid" in Mathcad. With animation!  

Hello everyone, This is my first time ever using MathCAD. I have no ideas but watching some video help me to create this sheet. I got the error unit of Cp (heat capacity) = BTU/lb*F. MathCAD error is value should be scalar or matrix.   I also set up the ODE function. Would you please help me to take a look this and guide me where I was wrong?   Thank you so much for your help. I attached the file in this post
