Mathcad

Hi all I am trying to include Mathcad files where I use a variable as a part of the file name. i.e. when I change the variable, the name of the included file changes. I want this for Mathcad 15 and Mathcad prime. Thanks

I downloaded and installed Prime 7.0 and the new converter that is supposed to convert MC15 worksheets to Prime 7.0 worksheets.  The first two MC15 worksheets I converted were claimed to have been converted, but did not work properly in Prime 7.   The more complicated one had a plot which uses a format that may not be supported in Prime 7, but the second file is a mystery. It is an extremely basic worksheet, so basic that it could be argued that I'm wasting the power of MC, but the file does use units. After conversion, the Prime 7 worksheet would not work until I removed and replaced at least some of the units and the PI symbol.   It seems as if the converter is unable to properly recognize and convert unit symbols and PI. If so, this is a massive fail.   Three files are attached. The MC15 file, the Prime 7 file as converted, and the converted Prime 7 file as fixed.   If I am making some stupid mistake, please let me know.

My print to PDF does not fully print Pages on the right side. Chops off most of the right-hand side of the sheet. This is what the PDF looks like.   Eg: The visible part when I try to print is: This is what the Prime 7screen looks like.       Any particular settings I have to enable? Thanks  

Hi all, See attached worksheet.  I took these equations out of a engineering paper and I cannot get them to work.  The find function is creating an error.   Thanks, Dan

I'm pressing the check box to say that I am requesting the installation thing for the 30-day trial and it just puts me here.

I've added the following solution to the Rosetta Code task: Function Composition   The new Mathcad entry is at https://rosettacode.org/wiki/Function_composition#Mathcad     This would be better implemented in Mathcad 15 or full Mathcad Prime (ideally a version before PTC removed partial application) - these versions would (should) allow a cleaner and more functional version of compose.   Stuart

Hi,   I bought a ptc mathcad license yesterday - but I'm still waiting for that license to show up. My evaluation license expires tomorrow.  Is it possible to extend my evaluation license since I've already paid for a full license?   I've tried posting this questions on two other occasions - but both were marked as SPAM for some reason.     I'm not spam.  I'm a customer.   Jon Cooke sold me this software (he works for ptc)

Hello, I am studying at the university and we need a mathcad for study

Hello Experts Need some help with iterating the solutions with time as a variant.  Castle 

Hello!Is there, in Mathcad, some possibility to hide the units in equation, which is presented using explicit function from Symbolic toolbar, and show unit again at result?Why Mathcad do not have such possibility to hide units in some part of equation and present them again if this is necessary for example at result? Best regards,Illimar Kalk

I'm sharing a recent long-form interview that PTC's CAD/engineering calculations general manager, Brian Thompson, had with engineering.com: https://www.engineering.com/story/video/for-power-mathematics-retire-the-spreadsheet Alongside with the video interview, there is also a written transcript. You don't have to share any of your own information to access it.   For Power Mathematics, Retire the Spreadsheet   Brian talked through a wide variety of topics, including why engineers and research scientists across many various industries choose PTC Mathcad and how those customers use it, the old and painful days of trying to perform complex calculations in spreadsheets, and some glimpses into the future of Mathcad.

I am still in the process for which version of mathcad to go with. I was wondering if you would be able to help me out. I did a conversion from Mathcad 15 to Prime 7 but it seems that it converted the table in 15 to a matrix and now none of the equations work anymore. Is this something you can help me with?

This non-Western font (in the red circle) has been appearing for some time in the print preview phase. Is there a way to delete it and not make others appear?I thank those who will answer me.

I have registered myself to PTC. Recently we have upgraded our IBM i OS from V7R2 to V7R4. Now we need to upgrade Implementer to 12.4 and we have some issues downloading this software form PTC site. It would be great if you can provide us CD/DVD to upgrade Implementer on out IBM i systems.Let me know if there is any process to be followed up.

Hello,   My evaluation license expires tomorrow (Saturday, September 24, 2021).  I have already purchased PTC MathCAD.   Since it will take a few days for my license to get delivered - is there any possibility of extending the evaluation license?      Thanks

Together with my students, I made animation that helps to understand what a cubic spline is. One student sent me this beautiful spline  

Hi all, first post here.   I'm trying to learn a bit more of Mathcad, instead of solving problems on several lines of Excel for a finite discretization.   The problem I’m studying is a very real and common situation of cascade gas filling.   It consists of a source (infinity size for simplicity) feeding start-empty vessel (1atm) thought a regulator valve that obey a function critical or sub-critical flow rate f(Delta P), until both source and vessel pressure are equalized. Then plotting a Pressure Vs Time for that system. The pressure would ramp up (critical flow), then level horizontal to zero flow as the pressure accumulation at the end.           I want to keep the math simple, in the future to add z-factor for the gas compressibility factor.   p1=pressure source p2=pressure vessel (to be filled) T=temp (constant) V=vessel volume Cg=valve flow capacity SG=relative density MW=gas molecular mass ni=mole at P_tank empty (1 atm) nf=mole at P

I'm in that uncomfortable loop once again   I can't get PTC matched going due to a glitch with the licensing system.      I get this message (see screen capture) when attempting to install a license using the License Wizard.   So, what's the next step?  

How do you do the gradient of a column vector in Mathcad Prime 6 like I've done in Mathcad 15? See attached picture.    

I do not receive a link to download the mathcad express in my mail. Could you please help me?

I previously posted a version of this question, but did not get any response. So I decided to rephrase and try again.   I have been trying to compare the solvers (BDF, Radua, Stiffr and Stiffb) for stiff odes. Could be doing something stupid but BDF is the only one that I can get to run consistently. For the others I get error messages I do not understand (in this context): "The return value of this function must match the problem size" "This value must be real" (BTW. Documentation says Stiffb does not work for more than 8 equations, but it seems like it should be "8 or more". 7 worked. 8 did not.) Thanks to anyone who chimes in.  If you run the worksheet, be patient. It takes a while to calculate.   

I've added the following solution to the Rosetta Code task:  Ackermann Function   Here is the link to the solution on the Rosetta Code site:  https://rosettacode.org/wiki/Ackermann_function#Mathcad     Stuart

I need to rant about how rubbish Prime is, so I am looking at the support renewals and its coming in at like £3k for my current licenses. We only use MathCAD 15 as prime's functionality is so poor compared to MathCAD 15. So what am I paying for? I sat through a 30min webinar on Prime 5.0, the only thing that they had done was add a graphing app, I had to temper my annoyance that that was the focus for the prime 5.0 release. What about the simple stuff:- 1. Why have they changed how you do subscripts! Every time I type a variable I add a subscript, this is now a two button operation. Did the developers ever open up MathCAD 15? I have been through multiple software upgrades on AutoCAD, Solidworks, Inventor etc none of them just decide to change how the user fundamental interacts with the software. 2. Why are there no formatting styles available? Prime is there to present maths in a nice consistent format so we can deliver it to our clients, did the developers forget that the output from
