Mathcad

I have created an Excel document in which I calculated the start and end coordinates for strips. The total number of strips is 23. I generated the strip data using table options in Mathcad.Now, I want to perform the same calculation for strip start and end coordinates directly in Mathcad. Please refer to the calculation used in cell F42 in Excel. How can I replicate this equation in Mathcad? 

Make sure Make sure "Random hardware addresses" is turned off in Window’s settings.My Mathcad Prime license file wouldn’t recognize my computer with  "Random hardware addresses"  turned on,

I have purchased a key for Mathcad for an employee at my company. I purchased it with my computer. I am trying to get it set up on his and cannot find a product key anywhere on my end. There are dozens of codes and numbers but none that are titled "product key." Additionally, all support videos seem to be for older iterations of the website and do not help. Similar problem with the knowledgebase articles. Any help on setting my coworker up with Mathcad 12.0.0.0 Prime would be much appreciated. I can provide proof of purchase if need be.

Hi, I am trying to solve an ODE to model a “Ball and Cone” tuned mass damper. The equations simulate a ball mounted inside a pair of cones with mass on top. The ball oscillates up and down an inclined slope with a curved region at the apex between the up/down slopes. I am using Radau solver as it is a stiff equation. Adams/BDF “does not converge”. The 1st solve block uses a simplified simulation for base excitation of the TMD. Using Radau with modest levels of damping the first solve block result gives a discontinuous response which should not happen given the inclined slope is a tangent to the curved section at the apex. Any ideas how I can correct this discontinuity would be appreciated.I tried using sigmoid transition functions (2nd solve block) for the step between inclined slope and radius but this gives a large number error.The 3rd solve block includes an extra degree of freedom to simulate the tower on which the damper is mounted, which is the aim of the program. This won’t solv

Attached are two images of my solve block.The example in screenshot 192200 does not work.  🥴  I am trying to define functions to be used in the equation to be solved.The example in screenshot 192321 DOES WORK.😀  I have explicitly put the functions into the equation to be solved.NOTE:  I cannot define the functions with the MATHCAD:= because I later use the solve block to compute a series of 𝛼 for a series of the parameters inside the Ans(….).Is my non working example simply not possible, or do I have some syntax or logic error? Thanks for any help.Reg  

Team,I need to automate this for sequential integer values of n.Any ideas anyone?Thanks,Glen

I want Mathcad Prime 11.0.1.0 to solve a simple exponential integral and it returns a limit towards infinity no matter what kind of assumptions I give it. A negative exponential should always go to 0 for x towards infinity when tau is real and positive.If instead I substitue manually a new variable x  the integral is solved correctly How can I convince Mathcad to do the same ?

Hi there , I’m using mathcade prime 11I need to get the max values using max function regardless if there are positive or negative , how ever when I use [ I x I] I get different numbers , how can I get the max ? Thanks 

I am a student  and ordered Mathcad Prime 12 Student Edition. I verified that my credit union account was charged. I followed all of the linked steps in the email I received and got an error message: Access denied - Insufficient Privileges Our records indicate that your company does not have a current PTC Global Support agreement I have phoned and emailed Cleverbridge and have not had any luck in getting them to fix this issue. They incorrectly believe I have a billing problem which I do not! I am unable to speak to anyone at PTC about this because of the logic of your automated phone answering service.

Hello, I was charged for the automatic renewal of my subscription, which I don't want. Is it possible to request a refund? My order number is 538773813. I have already canceled my subscription, and I regret that I cannot provide the activation key for my license because it was not included in my payment confirmation email.

When trying to obtain the trial version of Mathcad prime the page says that my UK phone number is invalid and will not allow me to proceed. The country is set to UK.

I’m using PTC Mathcad 10.0.0.0 (as of May 2026).  Is this the latest version?   How can I determine if there’s an update?  Where do I check?  In the software?  Somewhere on this website?   Thanks

When I try to download my licence to install the 30 days pro version of Mathcad a Server error shows up

Maximum trial for licensing has been end but acquisition has not been done.

Hi people. I followed the program and installed the student version of Mathcad but can not start it on my computer. Any advice ?

I am looking to define the variable ϕ2.min based on the table below. I have created the variables for HC and HD to define them as HC1 and HD1 etc. however I am not sure how to then pull a value for ϕ2.min based on the below selection table.  Any advice here would be great!  

I am trying to specify the value of a variable based on the value of a second variable. The attached table shows what I am attempting to achieve is setting the value of B2 based on the value of d in-line with the data attached. Any help will be appreciated. Thanks 

I am trying to copy a 1xn matrix developed in mathcad prime 11 and paste it into an excel like table in ansys mechanical to build material curves for stress analysis.  I cannot for the life of me figure out how to do what seems like a simple task.  Is this an easy thing to do?

Hi,I have a file that can’t be opened by Mathcad Prime.I just get the message “File type not supported”.Anyone got any tricks to find ways to repair the file?I attached the file here in .zip format since mcdx format is not supported.

Hello, i have problem with installation of mathcad. I couldn't go next from ,,Aplication Selection'' window so i haven't installed mathcad yet.Thanks for help.

I could not find any other support, so I decided to write the message here. I am a student and our school uses Mathcad 11. I received a code for Mathcad pro from my teacher, but I am unable to activate it. I downloaded the software and it shows that I have the free version, and that I can activate the pro version by clicking a button on the top right. I did that and got to the licence assistant. I logged in and put the code in, but it gives me an error message "server error" after I try to install the licence. A link leads me to here: "https://support.ptc.com/appserver/support/account/contact_customer_care.jsp", but I either don't get any help from there, or I am unable to access it due to not having the correct web account. I am unable to upgrade my web account, because I don't have the data required to do so. The only thing I have is the code and the need to get this app so i can work with it in school.

Alguna persona que tenga acceso a MathCad que me pueda abrir un documento y enviarme los datos que tengo mi PC dañadahttps://drive.google.com/file/d/1S8_3PWGeUnYfnA4jiGYNd6JJ-22kekP5/view?usp=drivesdk

I want to buy Mathcad Prime but I can't login to purchase. I have created an account. When I click "buy now" it opens a new tab with a login screen. I enter my information and it says "invalid username or password". I have reset it several times and after completing the reset I can see that I'm logged in because my name appears in the upper right hand corner. When I go back to the store to purchase the license, the same login screen opens up, I enter my email and newly changed password and I get the same error. What am I doing wrong here?

I recently changed my laptop and I'd like to re-install Mathcad. Unfortunately I don't receive the link for the download and the same it's not in the spam.

Using Prime 11The topic is Hertzian contact.  I was investigating the capacity of spherical contact on a flat plate using several different methods of calculating the stress stateI converted a Mathcad 15 worksheet to Prime 11.  It worked perfect in V15.  In Prime 11, one of the functions is broken.Attached are the PDF of Mathcad 15 output and the Prime 11 worksheet that it converted.I’m using a bunch of nested solve blocks as functions.  The functions that use the Find solve block seem OK.  But one function uses a Maximize solve block.  This isn’t working.This function worked in Mathcad 15. sigma_eq is another function.  It’s supposed to maximizing the value of sigma_eq by searching for the value z_guess that gives the maximum.  The other inputs to the z_peak_stress function are “constants” that the function sigma_eq also needs as an input.Conversion didn’t mention any errors about this.  It added a ‘helper’ (?) equation that’s not part of the iteration.  And the new format throws an e
