Error message when entering PTC permanent licenseReboot attempt on wrong systemI have confirmed and the system data is correct, but the message continues to appear when entering the key

The bug is present in Prime 10 and Prime 9 (can't test with P8 and P7). Its not present in Prime 6 using the new engine! Prime 10 & 9:   Prime 6 with new engine (FriCAS/Axiom)   I hate to say it, but the very same example also fails (in a different way) in Mathcad 15 with muPad as engine, too 😞 Prime 6 sheet attached  

Hi everyone,  I'm struggling to write a program in mathcad ... I have A , C  points each one of them has its own x and y coordinate as showing below... what I need is to. 1) compare the two arrays2) choose the nearest point in A to C 3) calculate the distance between the near pointsfor example if A1 is ( 2, 3) and A2( 10, 30) ...and C1  is ( 6, 4)  and C2 ( 2, 7) .... the program will choose A1 for both C1 and C2 since A1 is nearer to them then it will calculate d1 =( A1^2+C1^2)^1/2 ,,, d2= (A1^2+C2^2)^1/2I'm using prime 9 Thank you in advance Yusra

Morning,I was using the free trial until the order was processed. The order has now been processed and I have received the PTC licence pack but cannot install it.

Hi Folks, The 'Chart Component' plot assumes an X range of -10 to 10.  When I zoom in on a plot, it doesn't recalculate so Delta-X doesn't change.  Curves are sometimes longer smooth (example below).  It seems like there should be a way to recalculate a plot after zooming in, but I don't see anything.  Am I missing something? Thanks for your attention 🙂 Mark    

Hi, I am doing an integral in mathcad prime. The function inside of the integral is a summation of series of if statement functions and a step function (for loop).  I plotted the integral twice (see attached figures), one with a TOL of 0.01  and one with a TOL of 0.1. However, the peak values along the graph are not the same at the same depth and I don't know why they are different since I am integrating the same function. However, the function stops at the same point (where the Moment is 0 kip*ft) at the very bottom.  I am wondering why the peak values are different by changing the tolerance. Thank you.     

Hi,Could somebody to say, why I could not write labels unit of temperature coefficient of copper 

I need to create a list of solutions to a function based on tabulated inputs see the below not sure how to do this in Mathcad

Hello PTC Community,I'm currently working on a project related to heat exchangers, specifically focusing on an economizer. I've attached some temperature characteristic curves showing the temperature profiles for both co-current and counter-current flow arrangements. However, I'm having difficulty adjusting the axes for both the x-axis (distance) and y-axis (temperature) to improve clarity and presentation.What I Need:Guidance on how to adjust the x-axis and y-axis scales appropriately to represent the temperature profiles effectively.Any tips on ensuring that the axes align properly with the temperature values and flow direction for better visualization.Your insights and advice would be greatly appreciated!i have added a mathcad prime file and a screenshot from my book, Thank you in advance for your help!Best regards,Michael

Hi, all.  I have just started using Mathcad. The problem below is driving me crazy. Any idea why it is giving me the wrong output?  See below. I have also attached the Mathcad file. Incorrect answer:Correct output: RegardsCP  

If you click on License under Options in Prime, a host ID is also displayed. I was of the opinion that this is the MAC address, called 'primary' by PTC, for which the current license was generated.But apparently there is some confusion here and it is a constantly changing fantasy MAC!!? I can't believe that this is intentional behavior, which is why I classify it as a bug. I am not sure but i think that in older versions of Prime the correct MAC was shown, the one the license was created for. I recently had to generate a new license and had it created for the one that was displayed. Of course this license file did not work. This was quite annoying, as license management is not exactly one of the easiest features on the PTC support sites and it took me some time and effort to finally move the license to the correct MAC.  

Hi there, I have this plot which has ( x, y ) and A and B are points in this plot>>> I want to show this point in different colour and then draw the vector of them ABand then I have  another x and y ( x;cpt , y;cpt different values) I want to show point C,cpt in the same previous plot then draw the vector component of AB and C,cptthe result should look something like this:not necessarily the same ,but I need to show the vectors Thanks in advanceprime 9 

I have an input matrix from actual test data, where I have taken out 5 test dataset(Speed and 5 pressures), showing first line belowI now want to do some calculations, get all the differntial pressures for example : I know i can do like this: but it would be much nicer to display the result as a table with proper colum headers and units, how can i achieve this?  

I have data in excel and I want to copy that data and use as matrix in Mathcad prime ? Is this something possible how can I do that? Let's say I have 10 rows and 100 columns and want to copy paste it in matrix is there a simpler way? Due to the nature of data I am unable to share here if anyone has a sample data to show me how that can be done it would be great!

Hi There,I want to know the difference between the MathCAD and the Students version MathCAD.Thank you

I recently upgraded my c:/ drive and Mathcad no longer runs. It fails the license. I get a message "The license you have requested contains an error." When I run the .licensing setup wizard I get a server error of 403 Forbidden. It was working fine prior to the SSD upgrade. Please help!

I have Mathcad 9.0 but bought the Prime 10 Student edition. I'm trying to upgrade/activate the license. Do I need to uninstall the 9.0 and install the 10?Also I never received my product code. I received the payment confirmation email where it stated "You will receive detailed information on the delivery in a separate e-mail that was sent at the same time as this e-mail." However, I never received a separate email. I can't find a place to submit a ticket. The only place I can find for support requires a product code.

Hi I am new to Mathcad Prime and I'm trying to solve a kinematics problem, and I really need help. I want to multiply 3 nested arrays, but in step 4 I encountered the error "These arrays elements must be scalars. They cannot be vectors or matrices." I suspected it was because they are nested arrays, so I tried to convert the nested array H1 into a matrix with a code I found online and now I encountered the error "This value must be a vector,"Any help is appreciatedThank you

I have been using mathcad for many years, its been my go to software to help me think and sort out problems. Very recently I moved to Mathcad prime 3. I am unbelievably dissapointed. Yes it looks pretty , but its so hard to do anything. I wanted to display arrays as a picture , as I have done for many years. You cant do this. You have to save the data to a file, then read in the file in to a picture which has browsed a filename. then it does not update when you change the data in the file. Its awful and unusable in this application. I have had to revert to a pre prime version as this actually does what I need it to do. I cant believe we are on prime 3 and this is not sorted out.Help doesn't work either. Prime really is a backward step and I would not recommend it to anyone - are you listening PTC. I have colleagues who feel exactly the same. If anyone can suggest how to view 2D arrays as pictures in a usable way I would like to find out.

Hello everyone,in the attached file, the program should loop through length of dS and store the values in RA. could someone explain me, why the loop is not workingattached the Mathcad 10 file.

I am having trouble understanding why I can't get a solution using the defined variables but am able to get one when I put in a value for the variable.  My issue arises because the values X, Y and Z depend on Twall.  I want to be able to loop this with an update to Twall at each dt.  Any help would be appreciated. mathcad prime9 .    

I want to show a formula as a step for reverence, not have MaffCad try and solve it,Can't see how to do it, there must be a simple way to add a formula like a text box?

Hi could you help me to program this one?And the previous generated function works without m to (mod..).see the picture.  

The help document describe as follows: but i copy it into my MATHCAD, it shows like this: I am not sure if it is the issue of software version. The document is for V10.0, i am using V7.0
