I have what I thought was a fairly simple problem, but it is giving me all sorts of problems converging.  Background: I'm solving for flow and forces on a valve to find conditions as the valve strokes.  So, I have flow through a series of orifices (solving for an intermediate pressure) and those pressures lead to forces that must balance against other forces (e.g. a spring).  So, it solves that without any issue.  Then I want to get more complicated and I use the solve block to calculate a simple parameter like flow velocity - then it starts having trouble.  Note, velocity doesn't affect the flow or force equations - I'm just looking for a value. Sometimes it will solve it, but I have to get the guesses right on.  So, am I not formulating this right?   The blocks in red are what cause a problem when I enable them.  I've tried many ways of entering the guess values but nothing seems very robust. Thanks!3.1 and pdf attached.

i am trying to plot this function S(R) but it keeps saying that it does not converge to a solution. based on the homework it says that it should be an exponential decay to zero but i don't know why it is not working out here. anyone know what to do? my functions and plots are solely just following my teacher's directions but it seems that it doesn't work as easily as it seems.

Hi everyone,is it possible to read (import) FAMOS raw data into Mathcad?  eventually with some kind of script?Some measurement equipment produce this kind of raw format.  The format description can be found in the manufacturer web page: http://www.imc-berlin.deAn example of what I mean can be found here, albeit with MATLAB:File Exchange - MATLAB CentralI would have a description of the format, but it is in German. And it is pretty complex Thanks for any hint!Best regardsClaudio Pedrazzi

   Hello Everyone.   The question : atan(1i*[1 - x^2i]/[1 + x^2i]) = a  assume, -pi/2 < a <= pi/2 , solve, x ?         Thanks in advance.                Regards.

Please see the screenshot below. PAEH's unit should be kN/m. Thanks,Vincent

In the same MATHCAD document, is it possible to have different headers (top page information, like date, title of calcul sheet, etc.) like Words for example? Thanks

Please see attached for formatting issues in Mathcad Prime

When I try to plot a user defined function on the y-axis vs. the independent variable on the x-axis, the independent variable is marked as undefined, and the plot fails; However, when I switch the positions of the function and the independent variable, such that the independent variable is on the y-axis, the plot works perfectly. Why is this the case? I need to plot the independent variable on the x-axis for the assignment I am working on. I have attached what I have so far. The plot is at the very end. Any information will help! Thanks!:

Hi everyone ! I'm a student, Can anybody tell me where to download a free version of mathcad 15.0 ?

Hi,I have a problem with an integral. Symbolic evaluation resulted in a "hypergeom" function. The problem is Mathcad 15 does not recognize its own function "hypergeom". Is this a bug? Does anyone now how to deal with this problem? I am interested in solutions for 'z' larger than -10 in this particular example (away from the singularity).Best regardsRafal

Hi All I am currently trying to solve the following equation for Dc. I have tried to do it as seen below, but i dont know if i am getting this completely wrong? Any help would be greatly appreciated. Many thanks in advanceDaniel Wright

Hi,Am I being really dumb... integral of exp(cx) should be exp(cx)/cMathcad Prime gives me integral of exp(cx) = x*exp(cx)I'm confused, what am I doing wrong?Thankyou.

Hi, I changed my hard drive, so now  I want to activate my licence of Mathcad but a message say that I've already reach the maximum number of licences. What can I do?

1.create a Java application program that will add up the cost of three items, then print the final total with sales tax. it is part of my assignment.I tried but mine wont compile. can some one do this a little quick and post a screen shot. use java.

Hello everyone !It seems to me that symbolic calculation works strangely when applied to scalar product of two vectors, even if I use vectorize operator.The consequent error message "Divide by 0" is then not so unexpected... Or maybe it's me who's wrong there.What's the meaning of the bar above T in one of the symbolic results ? (attached worksheet).Many thanks, Liv.

HelloAttached the mathcad program and pspice simulationthank you

Can someone tell me how is this possible ? I gues it has something to do with rpm unit. Can i somehow redefine this unit to work correctly ?

  Hello Everyone.  The question : e^x = [e^(x*1i)]^-1i ?  Thanks in advance.        Best Regards.

In the case of numbers, like tan(2), the Help provides clear information : figure after keyword confrac = number of accurate digits.But what is the meaning of this figure in the case of the function tan(x) ?Must confess that in the beginning it was a little bit confusing the display of the development of tan(x) by continued fractions...(Pls. see attached)Is there some trick to avoid the very tall vector of terms ? Probably by assigning the result of the symbolic evaluation by confrac to a variable without displaying the result...? Or would it be possible to have it in a usual table to scroll in ?I think that for sqrt(x) and n-th root functions I have to look for in math books...Best regards, Liv.

Hi, I've just lost my days work. I have been working on a very large automatic file for use for non-mathcad users. I have backups but not of todays work. When I was saving, mathcad froze and now I can't open the file. This is for designing and frame for structural engineering. I can reproduce what I did but it was many hours work.I'm hoping someone can get it open. I've attached the 3 files that are in the folder where it was working last. Thank you!

helloHow to insert a Pspice data into mathcadthank you

...Hi all, .... a bit of Boolean algebra ... it does not hurt ...About sequential networks(Eugen Philippow - Taschenbuch Elektrotechnik Band 2)  (8.84) pag 651)... And here the going gets tough ..Who knows how to demonstrate at least one of this last five relations?Thank you very much.GreetingsF. M.
