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 

 I recently started using Mathcad Prime 12 for structural engineering / Eurocode calculations and I noticed something frustrating regarding the unit system.Mathcad correctly understands that: kg/s² = N/m. However when working with line loads (common in structural engineering), Prime often displays results as “kg/s²” instead of the expected engineering SI unit: N/m or kN/m.The strange part is that under “Insert Derived Units → Force per Length” there are several imperial units available: kpi, klf, plf. but there is NO SI alternative such as N/m or kN/m.This creates a awkward workflow in SI-based calculations, especially for Eurocode and structural design where line loads are constantly used.Currently the only workaround that i found seems to be manually dividing by (kN/m) , creating display variables or manually writing the unit as text. This partly defeats the purpose of the otherwise very capable engineering unit system.Questions:Is there any hidden way to add custom SI derived units

Hello All, The following symbolic evaluation used to calculate without any issues in mathcad 15. It does not evaluate in Mathcad Prime 11.0.1.0. i have attached the sheet,Regards,Sam   

Hi all,Last week we released PTC Mathcad Prime 12.0.0.0. We’ll be sharing more detail on www.ptc.com soon. A handful of users reported an issue with the release.Currently, PTC Mathcad Prime 12.0.0.0 will not run if it’s installed on a system where the system language is set to one other than one of the ten languages officially supported by Mathcad (US English, French, German, Italian, Spanish, Japanese, Korean, Russian, Simplified Chinese, and Traditional Chinese). If you run Mathcad Prime 12.0.0.0 on a system using one of those supported languages, there’s no problem. If you can change your system language to one of those supported languages, Mathcad Prime 12.0.0.0 will run fine. But if you need to run Mathcad Prime 12.0.0.0 on a system language not officially supported by Mathcad, you should remain on PTC Mathcad Prime 11.0.1.0 until this is resolved.We’ve been working closely with Microsoft on this issue and have identified a fix. We’re currently in the process of building and testi

I was having trouble to activate license, so I ask for that and instead of issuing license for my free trial PTC site offer me free Re-download 30 days trial which I accepted. The real problem is that I have never received e-mail to download that. I check my junk mail also and it's not there either. Please look it up to this and send me an e-mail with re-download link as I also try to re-download using old email for no use.

This month’s challenge is inspired by the greatest rock band of all time: Rush! Specifically, it is in honor of the 50th anniversary of their concept album 2112, which gave us the Starman logo. Here you can see the logo along with geometry in Creo pertaining to the challenge:Starman Star Challenge depicted in Creo ParametricNote that the Starman logo is not a pentagram, and Rush is not devil-worshipping music (as many of our parents thought). Drummer and lyricist Neil Peart (RIP) was really into Ayn Rand (which is arguably worse). The logo represents a naked man, armed only with his intellect, resisting the collectivism of the Solar Federation. Listen to the album. It’s awesome.Here is the challenge: start with a circle of radius 1. Inscribe a regular pentagon. Connect the vertices to form a star.Challenge 1: Measure the area of (1) the star, (2) the pentagon inside of the star, and (3) the tips of the star (the star minus the interior pentagon).Challenge 2: Write functions for these a

I re-downloaded Mathcad prime 12 to have it working properly but for some reason its not installing UI and because of that my its not working right

In the days before MATHCAD Prime… It was possible to annotate your analysis images with “Arrow Attached Text”.  It is no longer present.  One must annotate an image in MS Powerpoint before adding image to Mathcad Prime 11.    It makes tasks much more work going between other apps for graphics.  I add alot of “fabrication” pictures to my “Material Review” packages as I structurally review” in process fabrication opportunities.   Please consider restoring and even enhancing this former ability.    Thank you.

Good morning, Community,Please I need your help, I have converted some Excel workbook into Mathcad Prime worksheet, my problem is that the AI created the file but I cannot open the file in Mathcad Prime 11. Please see attached files for your attention.Thank you

Hi everyone,I am trying to activate a trial license for PTC Mathcad Prime 10.0.1.0 from Express, but I am unable to obtain the license.I successfully logged into my PTC account and completed the License Wizard. However, when I click "Acquire License", I receive the following message:"Error in License Processing. Please contact PTC License Management."No additional details are provided.I am using Mathcad Prime 10.0.1.0 on Windows and trying to activate the free trial version. I have already verified my email address and can log into my PTC account without any issues.Has anyone experienced a similar problem?Any help would be greatly appreciated.

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) 

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
