Mathcad

I have created a solve block but the block only returns my guess value as a solution which is wrong.

Hi Team,We are trying to retrieve our license from PTC. But it was throwing INVALID HARDWARE error. Could you please take a look and assist on this please?

Prime 6 does not appear to have a way to produce a grid on a 2D plot.  Without a grid, plot values are difficult to read.  Hopefully this glaring omission will be corrected in Prime 7.  It would be good to have major and minor grid lines, of different colors and weights, but as a minimum the plotting features of MathCAD15 should be included.  A related helpful feature would be to be able to control the orientation of polar plots.  A current need is for a polar plot with zero degrees pointing to the left rather than to the right, with positive angles opening counterclockwise.  One could imagine zero degrees straight up, with positive angles opening clockwise, or other orientations and directions.   I posted this before and got a response to the effect that showing a grid is possible in Prime6 by way of some kind of plot editor.  But I can't find any such thing anywhere in Prime6.  If some tool is to be used, it would be helpful to know where

See snip below & attached. I'm trying to solve for z_pna, such that the sum of the tension forces equals the sum of the compression forces. 

Hi communityI don't know how to use prime to find solutions to a robotic problem this problem is based on matrix calculus for a serial type robot it is easy to determine the direct geometry, i.e. to express the generalized coordinates according to the joint coordinates The difficulty is to solve the inverse geometry, that is to say determine the coordinates of the joints according to the generalized coordinates usually this uses Paul's iterative method I don't know how to solve these equations with Mathcad see the attached sheet

I need SCN so I can upgrade to network seatsvbottone@pagethink.com

I have a license for Prime 3.0 and am re-installing on a new PC after a few years away from Mathcad and require a download link - is there one available? Thank you.

I have on average 30 to 40 large Mathcad Prime 8 worksheets that must sequentially open, calculate using input numbers from an ASCII text file, output an ASCII text file for input by the next worksheet, then save and close before the next worksheet is opened.  This is very labor intensive and I need to automate the process with a Visual Basic program.  It is critical that each worksheet recalculate while it is open, to deliver correct and updated results to the next worksheet.  I can get the attached example VB program to start Mathcad and open a single file, but I have not been successful in adding lines of VB code, that recalculate that worksheet after it is opened, and then save & close that worksheet with the changes, before opening the next worksheet - and doing it all again.  Help!  Obviously, I am not a programmer!

Hi, today I tried to install free trial version of Mathcad Prime 9.0. Instalation was succesfull, but i can't activate my license. Every time when I try to acquire my license it shows me this message "You have reached the maximum number license requests for your product type". What should I do?

Hi I've put together a series of Worked Examples using Mathcad. These are aimed at for Structural Engineers in Australia and New Zealand as they cover AS/NZS Standards, although the general principles apply globally. Smash the 'Like' button, share the show with your friends, subscribe to the channel and leave a comment. Regards Andrew

Hi,I created a student account about a week ago to get the 30-day free trial of Mathcad Prime, but I never received the email with the license.

HelloI have an activated PTC Mathcad Express on my new computer and I need to convert Mathcad 14 Worksheets.The converter give me a "no license" error.Kind regardsReto

Is it possible to locate a reference file in the right margin of the document?  The intent is to utilize the reference information in calculations but not show as part of the printed document.  An alternative seems to be including the reference file in a collapsed area; however, that results in a solid line across the page when printed.  If this is the best option to include but hide a reference file, is it possible to disable printing of this region?  Again, I'm not wanting this line visible when printing formal presentation documents.  In Mathcad 15, I could turn of the time line, date, etc. and then highlight the region with a light color that wasn't visible on the printed document. Thanks,

Does anyone know why I get an error message when I convert from MathCad 15 to Mathcad 8 prime or does anyone know what this printout does in general?   Translated by the Community Moderation using Google Translate -----------------------------------------------------------------------------------------------   Weis jemand wieso ich beim konvertieren von MathCad 15 auf Mathcad 8 prime bei diesem Ausdruck eine Fehlermeldung bekomme bzw. weiß jemand was dieser ausdruckt allgemein macht.

Hello, EDIT:I understand that in the first case I take for i a column matrix:   And in the second case I take: How to loop the n column matrix in t?  

Stupid question...I'm just getting back into MathCAD (Prime 7.0) after several years absence...I'm trying to see if create a simple routine that will automatically strip the units from a variable and display only the numeric portion...so I can turn it into a string and use it in text functions. Essentially what I have right now...The routine divides out the SIUnitsOf(variable) and multiplies that by a conversion factor that it sequentially looks up in a matrix.And it divides the variable by the conversion factor's base unit (from the same matrix).When I type out the procedure for an individual case, it gives the expected answer.When I try to put that procedure into a "for" loop, it gives me an unexpected "These units are not compatible" error....can anyone see what am I doing wrong?

Hi All, I have been given the task of trying to make this MathCAD program work in Prime. It works perfectly well in MC15 but throws up unit errors in Prime.  I was guessing that it had something to do with the unit which is Newtons, which I added in, but it still doesn't work. Any advise on where this is going wrong?

Hi Bill, Reference topic  - https://community.ptc.com/t5/Mathcad/Beam-bending-using-finite-differences/m-p/884208#M207256I was just wondering why I tend to get failures if I run this multiple times within the same MathCAD sheet (i.e. cut and paste it several times). Usually I can get away with running two different runs (usually x and y) but if I'm looking at multiple items, despite clearing what I think are the important variables, it always throws up an odd error? Do you know if there is a reason this would happen and good places to trouble shoot when it does?

See image below. I tried giving K_t units of "inches" but that doesn't work. 

I am trying to run the code but at this sectionI get this error. Why?

I've searched as best as I can to find any reference concerning controlling the units as they are passed from an embedded Mathcad Prime 9 file to Creo (9.0.4.0). I'm aware of the "locked-down" default unit system sets available to us in Prime - please PTC fix this and add the functionality like we had in v15 to establish our own default unit set!!! The issue stems from our Creo part model having units set to "mm", and Prime insisting, of course, to only pass results back to Creo in "m" (or in "cm" or "in" if selected as the default). Is there any "trick" to force Mathcad Prime to pass result units back to Creo in "mm"? BTW, I know we can strip the units and simply send back a numeric value by dividing the result in Prime by "mm". The challenge there is if somebody wants to switch unit systems in Creo, the process will return incorrect values from Mathcad.In the meantime, I'll post an enhancement request in that section of the Mathcad forum to add custom default unit systems. Thank

Hello, On page 7 of the attached sheet, there is a solver that existed in the sheet i created in mathcad 15. When i converted it to Prime 9, it removed the syntax "Given" and it aslo  states undefined variables. I dont know how to fix it. Thanks,Sam  

I always wonder why, after a walk in the park, some of my shoes remain clean, while others are always smeared with dirt. I videotaped my walk and realized that the reason was a large welt of brown boots. Drops of water flying up can get on the shoes only if they have a certain trajectory, which depends on the initial conditions (Cauchy problem). Now I am trying to create a mathematical model (ODEs) of this process in Mathcad. Who can help me? May be this problem was solved! 

Hi, I have a perpetual license of Mathcad Prime 3. Now I am trying to install Mathcad on my new PC, but the only version I can find available for download on PTC's website is 9.0. I tried to activate my license on that, but as expected it did not work. Following the recommendation given in a similar thread in this community, I also tried to contact the vendor (digitalriver.com) who sent me the license back in 2014, but it seems like they no longer work with PTC. Can anyone from PTC guide me on how to install Mathcad Prime 3 on my PC? Best,Felipe

Forgive me, I am new to Mathcad.  I have created a simple equation in Matchcad and it appears to be giving me the incorrect answer. When calculating the same on my calculator or in a relation in Creo I get the answer: 32.2275... Does anyone know why this is the case?
