Mathcad

hi,   i wanted to use a square wave to drive a mass spring damper system. i usually use the state space solver, as it has worked better than the other solvers. however, in this case, i get an error. note, the worksheet isn't fully setup yet, due to the error. i was trying to make an example, since there aren't any quick sheets for a square wave.   thanks,   anthony

Appreciate if anyone tells me what the code in the attached image mathematically means? Thanks in Advanced  

Hello,I am generating a MathcadPrime 3.1 document with c# using the interop "Ptc.MathcadPrime.Automation.dll".Everything works fine, but I like to save the worksheet as a pdf as well, I do not find the corresponding save as options, Mathcad 15  offered MCFileFormat.mcPDF format. Does something equivalen exist for MathCadPrime 3.1 .´Thank you in advanceJan

Hi all, in my first post, I've been pulling my hair out as to how to assign and format units correctly.   In the plot within the attached workbook, I would love the axis to be labelled (x)psi & (y)lbf, but I'm out of luck trying to get them there with the auto-formatting which mathcad employs.   Any hints would be gratefully received!   Thanks Andy

Hello,I want to create a square wave train with 40 kHz frequency. The problem with the attached worksheet is 1- it doesn't start from zero amplitude2- I don't know how to add the factor (x-vt) , x= position and v=the sound speed, to simulate the wave train propagation in "x" direction.Could you please give me some hints.All the best Payman

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

It is the site of the chapter 9 the Ochkov's book (in construction)  

Could you help friends?  

Whenever i try to do something everytime program exist with this "an unhandled exception occurred on the dispatcher thread" error. I am using Wİn10 64-bit and i installed mathcad properly. could not findanything useful at the website or forum to help me. Please help

Hi PTC Mathcad Community, I have this Mathcad Prime 5.0 file in which many regions are apparantly corrupted. I think this is due to having math regions inside text regions. This is the first 3-4 pages, and the last few pages are ok.   Is it possible to fix the file?

Appreciate if anyone can help to solve the units issues in the attached file  

Has any one used MathCad to take 2D images (e.g., bitmaps) and render a 3D point cloud from them? Is this do-able with MathCad? 

I want to evaluate G(s); however it say its not compatible.  Why is this, since its simple multiplication?

I have the problem of "Units are not compatible" appreciate it if anyone can help?  

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

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
