Mathcad

I'm hoping someone might have a quick workaround.  Some years ago we purchased 25 permanent academic student licenses of MathCad 15 from PTC.  I understand that PTC no longer supports MathCad 15 and I've read the FAQs related to the changes.  While the FAQs warn against the risks of continuing to use these licenses, it does say that permanent licenses will still work.  Unfortunately when I now try to verify the Product Code through the MathCad License Setup Wizard and use the usual "acquire a license via the Internet" and then enter the Student educational Product Code along with my account login, an "Unexpected Error" window pops up pointing out that "The trial program software you are requesting is no longer available."  It then points me to the website to purchase the latest version.  The PTC licensing management team is aware of the issue and suggests that they are looking into recreating a permanent tool that will allow those of us with Product C

Hi Folks, I have what I think it s a simple question.  Solve blocks seem to require a bunch of needless space.  Is there any way to eliminate this?  V15 solve blocks were a lot more flexible. Update:  I asked a similar question about two years ago.  I'm just trying to find out whether PTC has made any progress on this. Mark   

I am in the IT dept of my company and we use Mathcad Prime 9. I have a user who wants to know if it is possible to convert MathCAD 2000 files to a Prime 9 compatible format. I am not seeing much online about this so my expectations are low, but if it is possible please let me know.

Hi,Seems that Mathcad Prime 10 does not allow anymore this. How to do in this case?

Is there a shortcut way of making optional parameters in a function in either M15 or Prime 3.0? I haven't come across anything regarding this issue yet.I ask as this would be a great way to implement the same function with some options. We could use [] to define the optional parameter with the number inside defining the default value.

Hi there,I have a rather long (50+ pages) mathcad (Prime 9) sheet that I have built to be fully parametric. After changing one of the variables I suddenly find that one of the functions is not working as intended without an apparent reason. I have located the source of my problems, but I cannot seem to comprehend why is it throwing this error. I am using root function to solve for the location of the critical x as shown below. In my previous iteration for a different set of input parameters, this function worked as intended, but as I changed one (in this case L, though I doubt it matters too much), I am getting an error that these values cannot be compared even though they are clearly the same unit and allow for algebraic operations such as addition, subtraction etc, but when compared against another variable of the same unit I get this error. If I manually create a new variable, lets say y.crit and give it the exact same value ( through key input ) everything works again, th

Hi,Why is it written that for subscript in text one needs to press ctrl+- and for superscript in text one needs to press ctrl++, while if someone press ctrl+- and ctrl++ it comes out of the way of being able to use subscript and superscript in the text. Is this indication written wrongly?  

Given an ellipse E in the Cartesian coordinate system with the semi-axes a > b and the equationx^2/a^2 + y^2/b^2 = 1. A chord AB of fixed length s < 2*b is considered. Let the point P be fixed on the chord so that the chord is divided into the segments AP = u and PB = v, i.e. u + v = s. The points A and B should now be moved on the periphery of the ellipse in a rotational direction while maintaining the chord length s and its pitch P in u and v. During this movement, point P describes a closed curve K.The content of the annular area bounded by E and K is sought.

Why is the PTC process so convoluted?😫😫  This is the reason I never use PRIME and stick with MATHCAD 15.  I am one of the respondents totally disgusted with PTC as noted on this forum thread.https://community.ptc.com/t5/Mathcad-Installation/MathCad-15-permanent-Product-Codes-no-longer-verified-by-PTC/td-p/815892 In order to help a friend decide on PRIME, I downloaded MATHCAD EXPRESS,  actually PRIME 10 30 day trial.  It supposedly installed because there is a PRIME 10 exe file.  I downloaded the license from my email.  When I try to run MATHCAD PRIME 10 for the 30 day trial nothing happens when I click on the MathcadPrime.exe file in the PRIME 10 folder in Program files.  It never asks for a license; it never installed a desktop icon.  It never showed up in my Start Menu.  Their so called instruction guide is pages long with no succinct summary.  I don't have time to study a lengthy installation guide for such a convoluted p

Hello sir,I've been using PTC Mathcad for buck converter design calculations. But we want to draw block diagram in mathcad. Is it possible, need support!!Regards,Krushna Thete,Accolade Electronics Pvt Ltd

I have MC Prime 9.0 and I've just install MC 10.0When I try to open existing worksheet (created previously with 9.0) it does not open with MC 10 but with MC 9.0.When I create and save new worksheet in MC 10 and try to open later on it, it tries to open it with MC 9.To open it in MC 10 I have to open blank worksheet first and then load desired file, kind of annoying.How to force opening old and new worksheets with MC 10? Do I have to remove/disable MC 9?

I was writing up the one of the Mathcad examples for CHAPTER 8: Earth Retaining Structures8.2 Reinforced Concrete Retaining Walls with Sloping Backhill. Could you please help me finding why the error massage was showing up?

  Can you please help me solve this issue? I don't see any faults on equation. Please let me know if I am overlooking at something. Thank you. 

Hello, Please let me know if PTC still officially supports Mathcad Prime 7. Is there any official PTC link where it is stated that this version of the Mathcad Prime software is officially supported? Warm RegardsVijay

Hi,I am making something wrong? Are only 3 differential equations... But using laplace command this system of differential eq can be solved:   See MCP9 file attached.

Good morning,I would like to convert xmcd files to mcdx format.I have Mathcad 15 software and a trial version of Mathcad Prime.The conversion is refused, probably because Mathcad Prime is a trial version.Could anyone convert them for me? I have about 15 files.Thanks in advanceRichard

How I can  tell matcade when the angle is divided by zero consider the value to be zero   

I'm trying to calculate the distance when I do it manually I get different results from the one mathcad givesLp1 should be the same of LP1I also need to write a program to make this function uses different fixed point , for example the first time it will use X1,Y1 (0,0) as fixed point and I get the values for Lp1 the second time it uses x2,y2(2,0) as fixed point and I get the values for Lp2 and repeat the process with the all points to get lp3, lp4 ... and so on

Good afternoon. I have clarified that I am a student at the time of installation. I don't know where to get the product code to complete the licensing process. On the other hand, I have downloaded the file that was sent to me via email called: sw_license_email_XXXXXX (6 numbers). I don't know how to open it since it won't let me do it.   Thank you. Greetings, Johanna.   Translated by the Community Moderation using Google Translate   Buenas tardes.He aclarado que soy estudiante al momento de la instalación.No se donde obtener el código del producto para concluir con el proceso de la licencia.Por otro lado, he descargado el archivo que me enviaron vía mail que se denomina: sw_license_email_XXXXXX (6 números).No se como abrirlo ya que no me deja hacerlo.Gracias.Saludos, Johanna.

Good afternoon,I'm sure someone on here can assist, we are fairly new to using Mathcad and we are struggling to get the lambda formula in the below snip into a Mathcad sheet, it throws up a number of errors and we aren't sure what numbers we should be adding where.  If anyone can assist, we would be very grateful.CheersSimon  

I have an already filled in Excel sheet with parameters and variables that I use in a Mathcad calculation. I could copy 'n paste the content to an embedded Excel component, but I'd like to avoid such menial task. Has anybody figured out whether and how to insert an Excel component that has content?
