Why is Oe in the SI list?  The modern developed unit is H in A/m. 

Hello Everyone. From: Thanks in advance for your time and help. Best Regards.

I am trying to solve a simple PDE which I solved in MathCad 15. I am struggling with Prime 7. Please help. Thank you very much.

Hello, The result to be obtained   Can we somehow show the result of the power p (t) (i.e. the multiplication of v (t) with i (t)) in an analytically way, apart from the graphical solution?Or, how can piecewise linear functions be multiplied analytically and the result can be shown, as above figure shown?   (   ) Thanks.

Hello all,   I am planning on making my Mathcad sheets more efficient and wanted the sheets to select by themselves from tables the properties of steel sections as shown in my screenshot. And recieve an output in my calculation sheet.   Unfortunately I have not come to a good solution. I managed to reference for example three different sheets with for 3 section types (each sheet has one table with all the section properties), but once Mathcad discovers the desired section in a row ( lets say row "x") it also goes into the following referenced sheets and reads the line x in all tables and gives me the output from the last sheet I referenced. How can I make Mathcad stop reading tables once it found the right table? Or do I have a completely wrong approach to it? Thank you very much already for your help, Joe

Some basic engineering (before I forget how)   In Prime 4.0

Hy,   I wanted to ask if there is a possibility to permanently reference the sheets in MathCad. The current problem is that once I send sth to a colleague, they have to reference all the sheets again because the path is not exactly the same. That would save a lot of hours to our team.   Best wishes to all.

Hi, I have my unit system is set to "USCS" in PTC prime 7, which I am using When I display an output for a volume, it shows up in "gal", and I manually change it to ft^3The same for weight, it displays as "lbf" while I want it in "kips". I do not see "ft^3" is a defined unit in the units menu!How can I get the units display in ft^3 & kip automatically for the worksheet I am working on?   Thanks

HiIf I remove the units from alpha the calculation executes without any error as soon as I insert units to alpha it starts giving an error not sure what I am doing wrong 

60 years ago, Yuri Gagarin flew around the Earth for the first time in the Vostok spacecraft!

I am trying to calculate the rise-time of this system, but I am having trouble finding the 90% of steady state (ss).Does anyone have an idea how to calculate the rise time of the system?  

I am a user of (real) Mathcad for a long time and now shifted to Mathcad Prime 7.0 and have started learning it. I am facing a problem in using symbolic evaluation in solve blocks using Mathcad Prime. It was a bit easy in (real) Mathcad but now I don't know what's the problem and why prime is not showing the answer. The problem statement in (real) Mathcad is  But when I use the same steps to solve the problem in Mathcad Prime it is showing a question mark with no hint of where the problem occurs. Please guide me, what am I missing or it is some incapability of prime that (real) Mathcad has for years.

Hey, I liked to know how to shift the values at matrix by a certain value like this. I have script in MathCad and matrix with hundreds values, and I need it to work automaticly. Thanks for help.

How can I import XML data into Mathcad    I want to parse and map date into a vector or matrix for an XML data   Vic

I was trying to get free MathCAD for students via this form (https://www.mathcad.com/en/try-and-buy/mathcad-express-free-download), but I didn't get a letter with download link neither on my local e-mail (mail.ru) nor my gmail. Is there a way to contact some support about these matter or what should I do now? Thank you for your answers.

Mathcad Prime 5 displays some really nice 2D plots but is it possible to do something like this? Sort of a hatch for the graph.  

Hello Everyone. Thanks in advance for your time and help.    Best Regards.

Hello,   I crashed MTC Prime 6 and the saved file is not able to be opened. The file is 1.3MB so I think the work should be in there. If someone could help restore the file, I'd greatly appreciate it.

Why i can not instal trial? I can not get my trial license

can't get a trail license. There is no program selection in the Acquire License window. The window is empty.

I am pretty new to Mathcad Prime and just learning things. Wanted to know is it possible to get all the possible solutions for the solve block and not just one?    I have attached worksheet. Thank you for the help  Vic    

My faithful MCAD14 no longer inserts functions. Insert|function does not open the function menu. Old MCAD files are also broken.

Hi everyone! I am having some trouble with my aerodynamics homework.  Does anybody know why am I getting this error? Thanks!

  I am moving some calculations from Octave (open-source MATLAB clone) for Prime 7.0. One of the calculations involves fitting a double exponential pulse to measured data. In Octave/MATLAB I use the lsqcurvefit function, which executes very quickly and appears to give me reasonable answers.   I am trying to find an equivalent function in MathCAD Prime. I tried genfit and LeastSquaresFit - for genfit I get a regression not converging error, for LeastSquaresFit I get  a floating point error. I even tried using the output of my MATLAB calculation as the guess value and still get these errors.   Here is a screenshot showing the function I am trying to fit, the guess value (which is the output from MATLAB), and a plot of the data and the fitting function using the guess value.   I assume I am doing something fundamentally wrong here. In MATLAB I can start with a guess value wildly in error and still get an answer.
