Hi Friends,one short Question:Is - for an nonlinear model - the ERR variable at a MINERR Solve Block the same as the Sum of Squared Errors? (SSE)I have different values there.Thanks for helping and answering.Walter

Hey guys, Does anyone know how to allow maximise function to be under global assignment? Is that even possible?

Hi, everyone. I´m trying to make a calculation with different inputs values. I looked on the forum but with my little experience I can´t made it yet. May be, my case is more simple than the examples. So I prefer to askMy input is a diameter particle (x). With that I need to calculate Ti, and with Ti obtain n. Which is an efficiency.Then, it will be excelent make a table with my inputs "x"  on a column, and the efiency "n", on another column. Finally, make a graphic with both.Also, I take this oportunity to ask. In the future I will need to find the minimal number of "x", which make the efficiency n=1. The calculation is for the efficiency of a cyclone to separate differents particles depending of their size. So, I want to know in parallel with the other calculation in the same sheet, the smaller particle which I can have a 100% efficiencyI know is probably very simple to do, but I cant.I attached my problem. All the others variables, are constants.Thanks to all

To all,my Prime 3.1 version has stopped working like a fully version and does not allow me to use, for example programming on a calculation sheet.it happened already few months ago and it was solved with the help of some tech from PTC.they sent me the license file again, but i cannot discern what number of all the numbers that appear on the license file is the one that i have to use to re-activate again my license for Prime 3.1.this is really annoying.Still finding issues on Prime that i never had on Mathcad previous version.

Hi Friends,one more question.Here my sheets: In the first area I used Quasi-Newton and got fine results, nearly the same as the ideal values.But when I use LM I get much other results but both methods have the same SSE. could this be true?Thanks

Dear Sirs,i am having a lot of problems when i am running calculations in mathcad 15 and prime 3.1, am wondering if the problems could be related to my computer capabilities to run mathcad.can you please, suggest the optimum characteristics that i should have in my computer to be able to run mathcad 15 and prime 3.1 without so much crashes and delays on the calculation and saving times?because the programs crash so often i am trying to save the calculation sheet as often as possible, which increases the time that i have to dedicate to keep my calculation sheet saved, instead of spending time improving it.thank you in advance,Rogelio

  Hello, Everyone.  The Question : Is there a rule in the sequence of numbers : 1, 3 , 5, 28, 81, 704  ?         Thanks in advance for your time and help.                Regards.

I'm new to Mathcad.  I would like to know how to display row and column labels of a matrix.

I have a plan to animate the catenary problem (see Solver Mathcad 15 and Mathcad Prime)But see that it is impossible - see the picture without  number values.I hope in Mathcad Prime NN we will get debugging tools like as in Prime 14 but without this bug!

The PTC Mathcad team has been working with Microsoft on this specific issue, which was created when Microsoft fixed a bug in .NET 4.5 which then had an undesirable side-effect on how Prime is able to render multi-part text symbols. The most visible impact is that adjacent lines can become misplaced and/or disconnected.Microsoft has been working on a solution for us, but they will not undo their original bug fix. The fix they provide PTC will allow choosing between the old and new behavior by application.Due to Microsoft's Dual Branching Servicing Model the fix will need to be deployed in a Limited Distribution Release, which means that Microsoft is addressing Prime’s specific issue in a *hotfix* that PTC will make available to our customers. The PTC Mathcad team will test the hotfix once received from Microsoft, and as soon as we validate that there are no regressions we will begin making it available to customers.It is important to note that this issue is purely a visual issue and in

Hey...Is there a workaround for this?The "Result" box is greyed out...

Hey...

Hi Experts,I have here an ODE which I can solve in Mathematica explicite. The Solution is in the green box. But how can I solve this ODE in MathCAD 15?

Hi, i'm studying Green Functions.I need to obtain the positive eigenvalues of a function, at this time just for first six values, m=1..6Can i do this in mathcad Prime 3.1??there's a attached file.Thanks in advance.

Hello,Can someone please help me with an issue, in the attached file, i would like to write the complete range of data outputs Re(Zpq(f)) and Im(Zpq(f) to an excel file, in column A and B. How can i achieve it?Thank you

I am using the shortcut CTRL+ENTER with Mathcad 15 in order to add an addition with line break operator.Do you know if it is possible to do it with Prime 3.0?Thankk youEric

Hi everybody,I just finished installing Mathacd 14 on my Windows 10 PC.Whenever I try to click on the traces tab in the graph property windows it crashes with an internal error.I tried reinstalling and reparing it but neither worked.I hope you can help me.

Dear All, I have plotted the module of Hankel functions of complex arguments and I found an oscillating behaviour. What is the reason of this behaviour? how could be overcome?

Hello,I'm realtively new to MathCAD Prime 3.1. In my previous works I used MathCAD 14 but with this one I can't make this work. Especially the units.Basically, I just want to solve a system of two equations and I can't make this work right. That's why I need some help from you guys. I've searched a lot here, but the problem remains.At the end of the attached file there are two solve blocks. I want to solve them both, so in each one I do: Find(W_L1,R1), for example, to obtain result of the system, but MathCAD can't do that for me and I don't understand why. If I eliminate all the units and try to solve them, I think it does the math. Although, as this is part of my thesis work, I want everything right, including the units, that are essential.Thank you in advance for your time.Regards!

Hi, I'm new on the forum and inexperienced with Mathcad Prime 3, so I need help. In the attached sheet I just wrote the kinetic model for a CSTR, which is a simple system of 2 algebric equations. There are lots of parameters that are fixed and one, XFRC (conversione of the reagent), that must change because I have to plot the solution of the systemwith respect to that parameter. How can I do that? Thanks and sorry if my english is not perfect

I have some old Mathcad files I downloaded.  The are Peng Robinson based files and would do bubble point pressure, dewpoint pressure and temperatures.  They can be useful, but I have no means to update the files to the present Mathcad.

I would like to start printing of a series of worksheets from an external Application. The external application was created to collect worksheets, force modifications and update them. The printout to XPS give the ability to insert content dependent header/footer. What I need now is the automated creation of such XPS outputs. This is normally done by printing to "XPS Document Writer" (Windows 7). The SDK does not have a interface for printing - not in the default automation dll. Is there any other dll or any other way to do this?
