Odesolve - in Mathcad 12 OK - see please the pictureBut in Mathcad 15 and Prime - not OK - see please attach.Why?

Dear all,I am having an issue with a large program in Mathcad. I want to enclose a large number of formulae within a Mathcad function. This has been created as a program using the Mathcad "Programming" Toolbar.When I calculate the worksheet, Mathcad spends a long time (~10 minutes) calculating this program and eventually fails to do so, returning an unexplained "mpl_exception". Please see screenshot below:When the program was shorter, i.e. when it had fewer formulae in it, then Mathcad was able to successfully calculate the program, and it returned a result in a very short time. Please note this program is not yet complete, and I still wish to add more formulae to it.The program does not contain large loops, large arrays, or other operations that would understandably take a long time. I am confused as to why this program is taking so long to evaluate, and why it is not able to do so successfully. I would welcome your advice and assistance. Please find the Mathcad sheet attached to this

I'm trying to solve a set of differential equations, I removed the integral, but I don't know what exact information I'm missing. I'm getting the error message "you have too few equations".Also, is it possible to make mathcad solve this using laplace method?Thanks

Hello, Everyone.      Thanks in advance.          Regards.              Loi.

I am having trouble with the solve block on the attached worksheet.  It is using the maximize function within a solve block.  Please help me figure out what I am doing wrong.  The answer should be around 104 kip.  Adjusting the guess value does not help.  Thanks in advance for any help.

HiI am new to MC Prime 2.0, but I have been using MC 2001i and MC 14 at High School, but license expired when I graduated.On to the issue:I want Mathcad to solve some differential equations and give me out the function as a result likey'(x) = x+5y/4^2y(0)=2and then I pressy(x) = <answer comes here>and out comes the function that matches those conditions. I have no idea of how to this, except something about that ODESolve, but I can't figure out how to use it, and the web isn't at any help at all (neither the built in tutorial).By the way, it is all random numbers that I just pressed in the example

HiI'm trying to solve this differential equation using solve blocks, which I cannot do by hand......But I'm getting this error message.Can u please assist on what I'm doing wrong?

I have found a bug, which is really terrible!Prim 3.1 caclulates wrong mean and stddev values. It correct in MathCAD Ver 15 M0300!Can anyone here verify this?

I'm trying to solve a simultaneous differential equation.Do I need to use a solve block (which is only available in the full version) to solve simultaneous differential equation and it would work?

Sometimes when I evaluate a derivative symbolically in mathcad of a certain function, it gives me 0 when its not. can anyone help?

Hi experts,I have a sheet done (the demo) with a MS Access DB with DSN and OLE in Prime 3.1. See https://support.ptc.com/appserver/cs/view/solution.jsp?n=CS181327For this to get run you have to install: (See the Q&A resouce from the web below)Q: I'm working on a program and it compiles fine, but it gives me a "MSVCR110D.dll is missing.."-error. I run Visual Studio 2013 on Windows 7 64bit, I also use boost 1.55.0 and SFML 2.1. Google and a fellow superuser post didn't help me out. I got told to install c++ redistributable but that didn't help me either. I'm not that good with C++ yet so excuse me if I missed something. A: The D version is the Debug Runtime. msvcr110 means it needs to C++ 2012 runtime. The file is not redistributable so you need to install Visual C++ 2012 or the 2012 C++ Express Edition, too. Maybe one of your 3rd party libs depend on this file. I could run it as OLE and DSN. But my question is how to use a MySQL Connector ODBC. I have already installed the MySQL Co

While the main drive of the Mathcad team is the development of new features for PTC Mathcad Prime 4.0 and future Prime releases, we recognize the need to maintain Mathcad 15.0 for users who simply can’t move to the newest version because we have yet to implement functionality they find essential for day-to-day use. 15.0 isn’t going anywhere for the foreseeable future – we are committed to regular maintenance releases of the product until we can migrate the majority of users to the latest version of Prime.Mathcad 15.0 M040 is due to be released shortly – we are finishing up our testing and resolving one final issue with 3D plots. This MOR is slightly different from previous  ones – while it includes several critical bug fixes, we’ve also updated the core code to support current technology advances.15.0 is the result of over 30 years of development and in that time many operating systems have come and gone. With many users opting to continue utilizing 15.0 we made the decision to ce

This worksheet gives the calculations of the temperature rise of the inner conductor, assumed solid copper, of a high power coaxial cable like the one used in Quetta (Pakistan) MW transmitter, 100 KW-1134 KHz. Temperature rise of solid state devices, transformers, bus-bars and transmission lines are very important for the life operation of these dvices.

High Power Coaxial Cable with Mathcad Prime 2.0This worksheet gives the calculation of the temperature rise of the inner conductor (assumed solid copper conductor) of a high power coaxial cable like the one used in Quetta (Pakistan) MW transmitter at 100KW and 1134 KHz implemented by Telefunken. Temperature rise of semiconductor devices, bus-bars, transmission lines and cables, transformers etc are very important for the life and operations of these devices.

I am using mathcad prime 3.1 and trying to solve a system of two 1st order ODEs with the odesolve command. I define the ODEs both in an explicit manner as well as in matrix form. In the first case the error that occurs is "Unable to form the derivative matrix" and in the second case "there are too few equations". Attached is a copy of the file I am working on. Any help and ideas would be highly appreciated. Many thanks,George

Hi,I am creating an excel table using the Excel component in Mathcad Prime 3.1. I am exporting the flow rate (which by default is m^3/s). I want it to be input into the table as l/s. Is it possible to do this without completing your own multiplication on the number (i.e. multiplying by 1,000 or whatever it is to convert m^3 to s). ThanksAndrew

Hi everybody,although I looked a little in past questions, I don't seem to find anything suitable.  I am confronted with the problem of reducing the sampling rate of a set of files, if possible with a variable reduction factor. For example setting reduction := 60 I would then have a value every minute, instead of a value every second, and so on. All my attempts are baffled by error: "insufficient memory for the required operation".I built an example with a limited amount of data, in order to show what I am trying to do. But the real files that I have got can reach 1.5 Millions of lines. They are also not readable with Excel.Moreover, the procedure seems to me very slow.  There has to be a better approach, but at the moment I cannot see it.Thanks a lot in advance for any hint!RegardsClaudioPS: a small collateral question would be if there is some easy Mathcad-way to convert the time stamp "hh:mm:ss" in a normal number (like for example seconds from midnight or so).

I am using Proselect in loop to select the model in drawing. and i am getting PRO_TK_PICK_ABOVE error . Can any one explain why.Regards,Manoj

Hello,My problem deals with a system of 2 second order coupled differential equations, Using Mathcad.I issue a problem with the "D" function (used to solve a differential equation) when there is more than 1 parameter inside.Here is the system with 2 parameters Teta1 and Teta2 :I convert this system to have only first order equations : Then, I can't find other way than making a D matrix with my 2 parameters Teta1 and Teta2Then, I issue my problem : its seems that I can't put a D function with 2 parameters in rkfixed method.So, if anybody here can find a way to solve this system, please let me know ! Any other method to solve it is welcome, of course !RegardsKevin

Sometimes when I evaluate a derivative symbolically in mathcad of a certain function, it gives me 0 when its not.... Also, when I try to extract real and imaginary parts of a complex function array, if I extract element by element, it gives me a number, but if i extract all at once, it just gives me [1x1], its a problem because I cannot graph the function. Also, assign the SIZE of a different matrix onto another variable?

Hello,I have got an important .mcd file which I'd like to convert into .mcdx, but the XMCD, MCD converter button in the input/output-ribbon is inactive, i. e. I can see it, but can't click on it.What can I do?

Hello, are there plans to bring back e-Book capability in future Prime releases?If not is there another software product that can take a Mathcad document and turn it into a book or publication document?Just curious,David Penwell -

Dear All, I would like to know if it is possible to create a cross-reference table in the new Mathcad version, like the option that we can find in Microsoft Word.thanks!

There is absolutely no way via PTC support to reactivate a licensed Mathcad version below 14 for any reason. Essentially, the program is hijacked for upgrading to a newer version.
