Mathcad

I’ve been revisiting Mathcad after some time away, and I had a question about functionality that used to exist in older versions.Back when I was using Mathcad 15, I remember being able to plot vector fields (for example, visualizing a 2D vector function with arrows over a grid) fairly directly using the built-in plotting tools.Now that PTC Mathcad Prime has been around for a while and has gone through multiple updates, I’m wondering:Does the current version of Mathcad Prime support vector field plotting natively? If not, is there any recommended or standard workaround within Mathcad Prime (without exporting to other tools)? Has this feature been intentionally removed, or is it something planned for future releases?I’m especially interested in workflows comparable to what was possible in Mathcad 15, where defining a vector-valued function and visualizing it didn’t require too much manual construction.Would appreciate any insights from those who’ve worked with both versions

I can’t figure out how to adjust the scale of the y-axis.  Is this possible? (see screen capture) 

It’s easy to add the vertical line marker - but now I can’t delete it.  How is this normally accomplished? 

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? 

Reference topicThere does seem to be a bug with Polyroots. I get the same error with the Quicksheet and a manually entered matrix of coefficients.If anyone can advise how to fix this issue  your advice would be appreciated. Ross 

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 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.

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

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

Ho comprato una licenza per mathcad ed ho ricevuto l’email di conferma da cleverbridge, ma dopo un meso non ho ancora ricevuto l’email da ptc con la licenza. Inoltre quando provo ad accedere al supporto tecnico il sito mi risponde che non ho l’autorizzazione per accedevi.

I've filled out the form multiple times, but I still haven't received the download link. I tried updating my profile, but I haven't received the required fields in the email. I only have the license files. I'd prefer the Express version, not Prime.

I’m trying to express the solution in mmHg as a unit for pressure. Is there any way to do this? 

Hello,I just started using MathCAD Prime 3.0 and stumbled upon a problem. I can't find a solution to that online.I have a question about this screenshot:Why appending a result to a variable makes the operation impossible (1st and 2nd columns)?Why showing the value of a variable makes the next operation impossible (1st and 3rd columns)?Thank you. (I hope this post is in compliance with the policy)

I’m using MathCAD Prime 9.0.0.0 and I’m running into a units error…All of the R units should be K/W, but I’m getting crazy units especially on Rmid. I attached my program as well as lecture notes that show how to do this. Look on page 44-45. Thanks,    Brent
