Hi
I have been plagued with a problem with Mathcad 15.0 (M030 [MC15_M030_20131216]) in which randomly I receive an error that says "Server busy.." When I click on "Switch to" it opens start menu. If I click on "Retry" it gives the same error.
I have tried searching online/this forums but I couldn't find a solution. Does anyone have any remedy for this? If not then I have to regrettably move on (or back) to Mathcad Prime 3 
Thanks
Omkar.
Hi All,
I recently formatted my laptop. So I sent PTC support for new licenses to install these two products. However when I receievd the licenses, I installed them in the respective MathCAD folders in the C Drive of my laptop. When prompted for licenses by MathCAD software , I point the software to the license path. But still neither MCAD 15 or Prime 2 works. I have tried all ways, but this licensing system is a big draw back on MCAD. This was the same issue when I tried to install last time also.
PTC need to work on a simple mechanism to solve the licensing issues. I have other software, and not a single software has these kinds of licensing issues. But MCAD seem to be a totally unproffesional software (not to mention the poor reviews of Prime1, 2 and 3 and their functionality). I wanted to upgrade to Prime 3, but due to the poor reviews and without any necessary improvements, I had put the upgrading on hold.
Coming back to the point, can someone advice me on how to have a smooth installation of my products MCAD 15 and Prime 2?
Regards,
Lakhvinder Singh
Hi
After installing mathcad and starting, it prompts for getting the licens file through the internet. When I give my user id and password it gives a message "The remote server returned an error: (407) Proxy Authentication required". What to do now?
Thanks in advance

Is it possible to insert an Autocad figure into Prime in a similar fashion as was done in Mathcad 15? Not copy and pasting, but rather inserting a CAD figure which you can double click and open to modify within the Prime software. It would be similar to inserting an excel component.
Dear all,
I have posted a similar question a while ago, and the general consensus was that it is not possible, at least with Mathcad, to symbolic solve a system of coupled second order different equation.
However, I have found in many papers and books writing out analytical formula of the solutions to the coupled equations. Attached is the system I am trying to solve. I have seen analytical formula even for one more mass. Although solving this sort of equation with two masses, no damping (dissipation) and with only one driving force is simple enough, even by hand, it is impossible to do the same for a system with two different damping constants and two driving forces. I have been trying for two weeks now, but could not figure out the solution.
Of course, I could get the numeric solution, but I could not get the same result as in Eq. 5. So, I was wondering if someone could help me with this. Although it would be perfect if it is somehow possible with Mathcad, but any solution to this problem would be of interest.
Any help would be gratefully appreciated! Many thanks in advance.

Hello,
i am wondering if is possible to make automatically content in Mathcad 15 like in Microsoft word? Anyone has expierence with that?
Thank you
Hello there.
Here I am again!
I've really been searching on this subject, but I can't seem to find out how.
In this arganddiagram (I've found it on the internet)
A line is drawn from the origin, to the coordinate, and the angle has been drawn too.
How do you do this (either in MC15 or prime) - It would really be great, as I have an exam on the subject monday :-)!
Thank you,
Ben
To all
I created an e-book following explanation in manual and it works fine. I am looking for a way of having the folder where I store all the mcad files of interest not in the MathCAD installtion directory (...\MathCAD/MathcAD 14/Handbook/ ) but in a totally different folder. I cannto find anything in the manual about that. (Probably not reading properly I guess!).
Thanks

Okay, how can I plot in degrees Fahrenheit?
I have a problem with formating. If I write a handout, documentation, article etc., I have to write formulas. If there are varibles in this formulas which haven't been used before, they get marked with a red box. Doesn't look very pretty. Is there a way to turn this off ....
Thx
Hi,
I have tried to solve a basic buck converter equations "in time domain", using functions (I am quite used to do it in a "discrete" way with fixed step solving). Unfortunately, the odesolve gives some very strange results. Thee current is suposed to go up and down in regular sawtooths going up or down according to the PWM function, but it looks like sometimes the solver skips some transitions, causing the current to jump in stupid ways.
I hoped using the odesolve would give me more resolution in the solution (possibly more than I can plot), but this doesn't help me in trusting the solver. Unless I did something wrong ?
Best regards
Adrien
Hello, everyone!
I've noticed that there is a friendly and helpful community here, so maybe you can help me out with my issue. 
I'm solving a differential equation with odesolve command, and everything works no problem.
Now I'm trying to add a periodic square wave function with variable duty cycle into the equation, and everything gets more complicated. I've used two similar methods to define the periodic function and they both work almost the same.
The trouble is - with bigger values of duty cycle it works flawlessly, but as soon as I try to lower it, it seems that odesolve misses some values and the solution looks obviously wrong. My first guess is that it is a numerical problem, as the equation also contains some relatively small and big numbers, changing some of which also helps a bit, but that's unfortunately not an option. Maybe there is an option to use some other method besides odesolve, or any other trick to fix this behaviour?
All other comments and graphs are in the attached file.
Any help is highly appriciated!
BR, Maxim.
Team,
I need to be able to assign a color, based upon wall tension, to a 3D graph of an ellipsoid. In a separate graph, I will also need to asign a color to change in tension in the ellipsoid.
Thanks
Hello,
I'm sure this has been answered before, but I'm wondering why I am unable to plot two vectors while I am able to plot another. I'm unsure of the tecnical reason why. I would appreciate any help with the issue. Page 3 currently has the plots that are not plotting correctly. I have also put some plots on page 4 showing that I don't think it should be the fault of a range being used.
I have inserted an excel component into a Mathcad worksheet. I have had issues preserving some of the excel features that were originally used. In one column, I used a data validation list to create a drop-down menu to control the inputs; however, once I leave the component and go back to the Mathcad workseet, the cell resets the data validation to allow any input instead of just the list. Is there a way to preserve the drop-down menu feature in the excel component?
I am working on a mathcad worksheet where I read data from external excel file. Every time I open the mathcad worksheet, it reads file and does calculations. My question is - is there a way to remember a previous value of a certain variable with its new value and calculate the difference betwwn two?
Hi,
I need some ideas on how to do the following:
I have two variables a and b, the sum of a & b is 10. I would like Mathcad to work out all the possibilities that give me a+b=10, and a keep in mind I would like them to be integers.
Thank you
Where is all legacy Mathcad stuff ( Electronic Books, free Add-ons for Mathcad 8, 2000, 2001, 2001i) ?
Much of it was/is loadable even by newer and current Mathcad editions !
I did not find anything here, also Google does not find anything special if I look for "Mathcad Electronics Books".
Btw, I am still using Mathcad2001i - no software activation, enough math power -, for my own internal development purpuses. It runs well on W2k and WinXP.
If an employer or project owner asks me to do something with Mathcad, I expect a current version of course :-), thats the business.
With the newer Mathcad versions, it is still possible to save in the Mathcad 2001i format (but not in Mathcad 2001 format, or older ) :-).
Sincerely
Rolf
The mhyper function seems to be acting strange in that it returns zero when the function is called with variables for the inputs and the last input is greater than about 70. I have attached an example worksheet that illustrates this.
I am using Mathcad 14.0 M020 (14.0.2.5), and a coworker using Mathcad 15 got the same result.
Is there a correction or work around for this?
