It would be great if Mathcad offers basic sketches which is always required in engineering calculations, with snapping options (grid, markups) along with tying the dimensions to the calculations. Sketches with the toggle option for transparent or opaque background would help in the documentation. Currently only option is using the PowerPoint saving as Png and inserting as picture in Mathcad (Which is involving and cumbersome).
Hi How do I program an if-loop with a range variable, and not a scalar? Is that possible?
Hello, What to add in below program for example in order to limit the values on x and y axis at: So that the graph does not have more than 10^307 points to display, even if the program has available to display more points greater than 10^307.Or what can be done in situations like this? I thought at below variant, but this variant does not differentiate in other type of cases like division by zero: If we run with the first program:
Hello,i don't want to read excel file to get the material properties for a given section. As you can see in the attached file, i copied the material section properties and pasted it into mathcad prime. Is there a way the user can select the material as i am showing below the table TC= " A22B", and have it look up certain section properties. I was able to do it in MathCAD 15. Thanks,Sam
Dear colleagues, I have used the attached "Outlier Rejectionprocedure" for over 20 years to detect outlier data from acquiredthermo-structural tests. I have tried, unsuccessfully, offering the procedure to AEDC (Arnold Engineering Development Center) because I use one of the twoOutlier Detection Methods but they have not shown interest.Therefore, I am donating it to the PTC Community. The method is a simple average of the of AEDC's and Chauvenet'sOutlier detection methods criteria resulting in the formula: C_ABC(n) = (C(n)_AEDC + C(n)_Chauvenet(n)/2 Where "n = sample size" Ultimately, entered the numerical results into TableCurve 2Dresulting in the formula provided in the attached workbook. I have successfully used to determine the outlier of: Bolt torque (n < 16) in a pipe-to-pipe flange assembly.Metal temperature around turbojet engine inlets, n < 24.Metal temperature around turbojet engine nozzles, n < 18. It is my hope that
Hello everyone,Please look at the attached MathCad worksheet.I would like to know if the solution block for my problem can be simplified by using the Minerr solver.The solution block must solve for 192 equations.Thank you so much for the time and help.Regards,CarlosRomero
Hello, OK Not OK?! Should not be ? x being any number Not OK?! Should not be ? x and y being any number
Hi I have a query on the backward compatibility of Mathcad Prime 9.Can I directly open in Mathcad Prime 9 the files created using Mathcad Prime 8 or Prime 7 ? I understand that for file created using Mathcad Prime prior to 7 and Mathcad 15, we would need a convertor. Warm RegardsVijay
Hi - I am exploring the possibility of having the calculation logic in Mathcad file, and then having the .NET web app take the user inputs and then sends the input values to a Mathcad file running on the server, and then get back the calculation outputs from Mathcad - which will be displayed on the web app. - Does the Mathcad API support the above scenario? I tried to check this link - Getting Started with the PTC Mathcad API | PTC | Mathcad - But it is not opening for me in either Chrome or Edge. - When Mathcad is called, will the Mathcad run in the background - or for ex; in case of a .NET desktop app which is using Mathcad installed on that desktop, can the user see the Mathcad window - when it is being called from the .NET code ? RegardsVijay
Hello, 1. I would like to know how many sign changes there are in this vector viewed as a matrix. There are 8 sign changes as far as we can see: So, here I would like a function that shows me 8 as output (the number 8 being the number of sign changes).2. I would like a function that tells me that at column 0 and between lines 1 and 2 is a change of sign, that at column 0 and between lines 2 and 3 there is a change of sign, etc. :
Hello I am trying to use Mathcad Prime 7.0.0 to solve equations, but no matter the equation, i have tried many, it always gives me Mupad_Unresponsive. Below is a simple example of the problem i have been encountering. P.S. I have tried uninstalling license, both in appdata and user, reinstalling mathcad, still doesn't work.
Where did I go wrong? Watt should be kg⋅m^2/s^3 Thus Watt/m^2 should be kg/s^3So the base unit reflected in the first line is already wrong (and the result off by x 100). I tried again by changing my custom unit in 2nd line and it confirms that the unit went awry somewhereThis is mathcad prime 8
I found a puzzle in the book store. It is 20$. I make it by Prime 9 worksheet. It says it has two answers. Try it!
I'm trying so solve an implicit differentiation example but I keep getting bad solve variable error This is my example:x^2+y^2=25
Hello, How to extract for example the 13th element from below?
I am upgrading an old application server and would like to know if there is a way to migrate the current version of Flexnet License manager 2016 along with my MathCad licenses on to a new Application server.
MathCAD is not working on my computer and I bought a license. I am using Windows 10 through Bootcamp on my MacBook Pro. The program will work for 2 days and then when I try to open it, the flash screen appears but the program never opens. I would delete matched and reinstall it but I ran out of the limits to use my license each time I reinstall the program.
I am using Mathcad Prime Release 9.0 and Datecode9.0.0.0Hello.When reading complex numbers from a text file (1 complex floating point value per line) into a vector, the following phenomenon appears: From the samples 500, 1000, 1500, ... (sample counting 0, 1, 2, ...) only the real part enters into the vector. I searched the vicinity of sample 500 for special characters that are invisible on the screen, but could eventually cause skipping the imaginary part during the reading procedure. I didn't find any special character except 0D and 0A (hex) "carriage return", "line feed"Here are the errors that I facedNo error message or warning
I am using Mathcad Prime Release 9.0 and Datecode9.0.0.0When searching for text or math in a document using the Find box and Find Next button in the status bar, collapsed areas are expanded but do not re-collapse if nothing is found. For documents with many collapsed areas this is difficult to manually re-collapse each one.1) Is there a simple way to collapse all expanded areas in a mathcad document?2) Can the find algorithm be updated to re-collapse any collapsed areas where nothing is found?My current workaround is to lock all collapsed areas, but this is not ideal either.Note: Mathcad Prime 8.0 did not have this issue, since find did not search any collapsed areas.
Helloi am having issues with units when i use the solve function. I have never had this problem before but it seems like whenever i use the solve function, some of the standard SI units are deleted in the process (the unit isnt bold blue anymore, which is what indicates that it is a unit). This is very frustrating because i need to copy the whole solved equation down and solve it again with a standard = then it comes out in the right unit, but i have never had to do this before, and in most cases i also need to define the units again in the copied solution... i attached a png of one of the times this has happened - and now it is happening in all my new files
I am unable to start my MathCad 15. Getting the message "The application failed because its side-by-side configuration is incorrect. Please see the application event log or use the command link sxstrace.exe tool for more detail." I am not a computer expert, and I believe to best fix would be to re-install my MathCad 15 app. What is your advice? How can I re-install my MathCad 15 app.
Initially posted in this topic Hi all, i can understand this for single dimension vx and vy, but what about 2 dimensions Mxy and Mz? Could anyone explain what cspline() returns and how interp() works? Thx in advance!LertNote: i use mathcad 15.
I bought and installed Mathcad 9 student version, on the day of installation everything worked fine, however today I wanted to open the program and now it opens Mathcad express, I tried to activate the license for the file again, however I get a message that says "(-9) Invalid host."Looking at some forums I tried to solve the problem by following what was indicated, however the problem was not solved.Then, checking the host, the one on my network does not match the one in the license file.How can i fix this?Thanks in advance for your response
I am computing phasor values of voltage & current waveforms at each sample point along the waveforms. I want to plot all of the resulting phasors, aligned to a-phase voltage. To do this I simple need to multiply each phasor by unity at an angle that is the conjugate of the a-phase voltage angle at that point. Is there a way to create a polar shift operator 1@-arg(Va)? See attached Prime 8 file for how I'm doing it now (multiplying by the conjugate of Va and dividing by its magnitude). thanks,russ
HI, I have successfully installed the MathCAD Prime 30-day trial. However, I am unable to open a pre-existing *.mni file (Mathcad Native Interface file).Does Mathcad Express support them? Is there any way to convert them to a file format recognizable by MathCAD Prime?Thanks! Eddy
