Mathcad

I have an MatchCAD Prime issues. Plotting the equation in MatchCAD Prime 7.0 is not working. There is notification like this "Plotting failed. Replace complex values and NaN by real numbers".

I have a trial version which expires in 15 days. i would like to upgrade to a student version as I found that Mathcad is extremely helpful for my assignments.

I had mathcad 5.0 working perfectly on my computer. I tried to install mathcad 6.0 and it got stuck at 1% and said there was a conflicting installation. I uninstalled 5.0 and I still got stuck at 1% when trying to install 6.0. Now when I try to re-install 5.0, it also gets stuck at 1%. I deleted the program files\PTC folder and checked appdata for other PTC folders. I'm not sure what's blocking the installation. It also says that .net framework and the other program it needs to install are already installed. The error it gives is something like 'please check logs'. The logs say Error 1622 after trying to do something with the PTC file.

I want adquire a PTC Mathcad License. I teach numerical methods at university level ¿ how do i obtain that?

Hallo,arbeite gerade an meinem Arbeitsrechner über remote desktop von meinem PC zu Hause.Die Lizenzanfrage ist fehlgeschlagen - und mathcad kann nicht ausgeführt werden:Fehlermeldung:"(-103) Cannot checkout an uncounted license within a Windows Terminal Services guest session" läßt sich das Problem beheben? Hängt das evtl. mit der Host-ID zusammen?(bin gerade in Quarantäne)

Hello Mathcad communityI would like to calculate the isotensoid contour of a pressure vessel and need help with the following calculations, because no graph is generated from the values. Thanks for any help.Seb 

Team,Why am I getting a zero in the Excel Component B1 cell? Note that I have been using Mathcad for decades. However, I've just started using Mathcad Prime. Kindly see the attached worksheet.  

I'm trying to parse a test function https://en.wikipedia.org/wiki/Himmelblau%27s_function using symbolic math. It has one local maximum, four global minimums and four saddle points.Why does Prime's symbolic math only output the minimums? Mattcad 15 symbolic engine produces the traditional answer - absolutely accurate and absolutely indigestible.Thanks for any response and comments. Attached files.

Hi,Mathcad Prime: Plotting Area. There is a gap below the plot where the axis expressions are which I have them hidden. Is it any chance to eliminate the gap? thanks,Eleni 

Hello everyone! I need your help. I can't understand why the program doesn't continue to calculate. It says the value of must be a vector.Please look at the attached file!Greetings from Germany  

On Jan. 21, 2022, Werner_E provided the solution for creating color-coded mesh surface plots using Mathcad Prime 6.0 for two functions [f1(x) and f2(x)] I had defined [Solved: Re: Generating a hemispherical dome surface plot u... - PTC Community]. Assuming that these instructions could be utilized to create similar plots with any other monotonic function, I defined and inserted two new functions [f3(x) and f4(x)- -see below] in the equation S = CreateSlices(f1, 0, a, 5): f3 = e–cx/a        f4 = 1 – x/a, both over 0 ≤ x ≤ a, with a = 300, c = 4.61 Evidently my simplistic assumption was incorrect- -the Insert 3D Plot command failed to generate the anticipated five-color slice hemispherical domes whose height ranges between 0 and 1.0. Where did I go wrong?    

Hi. My name is RomanWelcome everyone in the new year. I put the sheet into the structure of the stairs. It can be supplemented or improved for sure. Sometimes I used the good work of the participants of this forum and somebody will find some fragments of their work in this sheet. That is why I leave my work for everyone's use. Have fun. 

Hi,I have an image in a Mathcad Prime 7.0 worksheet and I am trying to copy and paste it to another Prime 7.0 Worksheet. When I attempt to copy and paste from one worksheet to another, it says "Browse for Image". Even when trying to copy an image and paste it into the same worksheet it says "Browse for Image". If I create a text box region first, I am able to paste the image into it, but the behavior of the image is now limited by the text box (cropping and scaling issues). Am I missing something here?

How to take out some part of the number defined through evaluation definition and use it further for calculation.For e.g. I have set of 3 number clubbed and 24 such sets separated by comma and space and would like to use 7 set for calculation purpose later in worksheet. Is there any possible solution for this

I am trying to make a plot of the dependent variable digital data (zeros and ones) in a column of a matrix vs another column (independent variable - x axis) that has units of degrees.  If I add volts units to the dependent variable it plots fine but as soon as I eliminate the units then the error "The values in the axes placeholders must be real numbers or expressions. Make sure the values are of the same type in both placeholders" is returned.The plot with the errors has the Y variable as a column of the matrix that is unitless.  The one that works has been fudged by adding units to that column. 

I am a novice Mathcad Prime 6.0 user and want to purchase a suitable hardcopy [print] user’s manual to expedite my learning curve with this software. The closest match my online search has produced thus far is a 2013 Academic Press publication titled Essential PTC® Mathcad Prime® 3.0: A Guide for New and Current Users, by Brent Maxfield. It appears that no such version exists for Prime 6.0. Are there enough similarities between the Prime 3.0 and 6.0 codes to justify buying the aforementioned book? 

How to determine the directory to which the program is written so that I can read from that directory explicitly 

Mathcad Contest Idea - January 2022 Plane Truss Mechanics Can you use Mathcad to solve this problem?   This comes from page 88 of “An Introduction to the Mechanics of Solids,” by Stephen H. Crandall, Norman C. Dahl, and Thomas J. Lardner. This was the text for the first mechanical engineering class (2.01 Mechanics) that I took my sophomore year at MIT way back in 1989. You can find the book for as little as $5 on Amazon. It shows three different solutions for the problem, including: closed-form solutions involving equilibrium of forces and the beam-deflection equation a computer program called IBM STRESS Castigliano’s theorem which solves via elastic energy. Any introductory mechanics text or a Schaum’s Outline should guide you to a solution. As with the other contests that will follow this one, the point is not the answer to the problem, but your execution of the solution. Some ideas you may consider including in your worksheet: Allowing the user to change the material via a

Hi guys Im getting this error below when looking at range of values in a table and trying to match the relevant density.  Sheet is attached, thanks guys  🙂

when running mathcad 15.0, I get a message to repeat the licence wizard configuration. At the end of this, I get a message like "this demo is no longer available2", however the software is not a demo

Hi guys I have 2 sets of data kz.b and kc and the refence variable z.b currently i can interpolation to find what kc is when z.b is equal to a value hence the below; however there a various values of Kcphi which i may need to interpolate between such as if kcphi was 6 i would then need to interpolate the value between kcphi5 and kcphi10 to then return the value and interpolate z.b to return the vlaue i am after. i was wondering if there is a function that could be written to help with this Thanks 🙂

Hi, I'm trying to plot a function but I get an error and I'd like to ask:Can I define a variable in a range between two other variables? and if not, how can I do it differently. Please see X3 variable and Y3(X3) function. thanks,Eleni  

Hi guys I have developed at mathcad worksheet that wish to publish to clients, the client has Mathcad licences and therefore can access sheets or templated provided.  Is there a mechanism to allow me to provide controlled access to my sheets/templates ? I believe there are two options 1 - REST API - access external data source to validate user credentials 2 - Build worksheet template for HTML and provide control with access via the webpage  If anyone has any experience with this please let me know thanks 🙂
