Our Mathcad Community forum has an Ideas section. They don't let me in there for political reasons. Thank God they're still allowed in here.The best idea for Mathad is to take all the good things from SMath.I will post pictures here describing some of the benefits of SMath over Mathad.I ask those who have access to the Ideas section to transfer my drawings there.
Schönen guten Tag,wir haben eine Mathcad-Lizenz und nachdem ich nun einen neuen PC bekommen habe, funktioniert der Zugriff darauf jedoch nicht mehr.Wie könnte man das beheben?Nach Eingabe des Produktcodes sowie Eingabe der Kontoinformationen des PTC-Kontos (ich habe ein neues erstellt) kommt die Fehlermeldung "Der Remoteserver hat einen Fehler zurückgegeben: (403) Unzulässig."Viele Grüße
This month we have another 3D geometry challenge. We are projecting squares onto cylinders and spheres and measuring the perimeter. Create a worksheet that calculates any of the following: Challenge 1: Perimeter Calculate the perimeter of a square with a side length of 50 onto the following: A sphere of diameter 100. A cylinder of diameter 100 and length 100. Clarifications: Note that the square is projected from a plane that is parallel to a plane tangent to the sphere or cylinder. It is projected in a normal direction from the tangent plane as in the accompanying images. For the sphere, the square is centered on the point of tangency for the plane to the sphere. For the cylinder, the square is centered on the middle of the cylinder and the tangent point. If the intention is unclear, please refer to the images or post a comment where the community can help explain the scenario to you. Challenge 2: Area Calculate the area of the above projected squares.  
In the attached file - a collection of 100 fractals. Used IFS formulas. If you want to add a collection - you're welcome.Viktor
Hello againI have (yet another) possibly trivial question.I want to make a program loop that will add elements to an array as long as the user wants to.Is this even possible in MathCAD?In python the basic loop would look something like below (formating difficult): answer='Y'counter=0array=[]while answer=='Y': answer=str(input("Add another? (Y/n) :")) answer=answer.upper() array.append(answer)print(array) This can look like this when run in Python:Add another? (Y/n) : Y Add another? (Y/n) : Y Add another? (Y/n) : n['Y', 'Y', 'N']
Hi, I'm struggling with a function within a solve block that requires two inputs, a force and an angle as shown below So when I evaluate R3(F1a,_delta_) I get the error that it must be a 3 element vector. I'm pretty sure my mistake is simple, but I just can not work it out. Any help will be greatly appreciated Shane
I have been trying to activate license but it is saying License request failed invalid host
I have a series of calculations that I've been doing in Prime 10 with no problem. Now that it is opened in Prime 11, I get a plot error "These array elements must be scalar". The plot still generates.It will not pass to a chart element and work.See attached document and data file. Any ideas would be appreciated. Bob Adams
I am getting error for programming could someone please help
Anyone have success pointing Mathcad to the Anacona3 installation directory? I have Anaconda Python. Root environment is v3.11, but I have a personal v3.8 environment. Both are supported by Mathcad Prime 11 for Advanced Controls. My installation for Anaconda 3 is at: C:\ProgramData\Anaconda3 Note: Anaconda doesn't like paths with spaces, so it installs in C:\ProgramData by default. This directory contains python.exe, python3.dll and python311.dll. I think this is the correct "Python installation folder" that I have set in Options. I pointed the Mathcad Options item for the Python path to this directory. Restarted Mathcad Prime 11. It still can't find Python in my Custom Control script editor. Hopefully, someone out there has gotten this to work and can shed some light.
Hi everyone,I wanted to share an issue I ran into while working on stress intensity factor () calculations in Mathcad, and see if anyone has advice on how to resolve it. When I calculated , Mathcad returned results with strange units: ΔK(a0) = 6.013×10^6 lb / (ft^0.5·s^2). That term in the denominator makes no sense — stress intensity factor units should be something like ksi√in (force / length^1.5), with no time dimensions.It seems that Mathcad is treating lb as pound-mass (lbm) instead of pound-force (lbf). Because of that, it introduces extra time units through when it tries to reconcile the dimensions. This appears to be why an is showing up in the denominator. Even after trying to redefine lb as lbf in my worksheet, Mathcad still seems to carry the time unit into the result. I can’t just delete the s^2 term — it keeps reappearing.Has anyone else run into this issue where Mathcad sneaks in an term when working with fracture mechanics equations? How do you properly set up your units
I don't have a customer number or SCN, just a web account to manage my license.I have a version of Mathcad 14, I know it's old, but it works for what I do.My problem is reinstalling it on a new Windows 11 Laptop. It is on my Windows 10 Laptop but after a Windows update the operating system failed and is irreparable. The link I had to the Single User License is:https://support.ptc.com/appserver/lm/mathcad/call_logger/callLogger.jsp, and it worked but after entering the product code I get this error message:Invalid parameter values have been passed in. The application cannot continue. I couldn't log a case from that screen as well. From what I'm reading MathCad license retrieval may no longer be supported. I May have to abandon it and go to Smath Studio or some other program.
hello: I am relatively new to Mathcad and rusty on how matrices work within the program haha. I am trying to clamp a minimum value in a 5x1 vector in a spreadsheet i am generating for wind loads. I have a for loop that generates a 5x1 vector for one variable To which i use GCpnegzone4 5x1 to generate wind pressures in the following loop Which works... however i need to clamp the values to a minimum of -16psf per code. meaning it should look like this: the approach i have been using is taking the same for loop used for Pnegzone4 and adding a the min function in hopes that it will go by element and compare the min value and replace when necessary. However the code just reports the lowest value as show below: Any help on how it should look like would be appreciated! my file is attached Thank you in advance!
I am new to PTC but not new to FlexLM license servers. I have one server with 3 different apps with their own FlexLM. I have another server with just one application so wanted to install this new PTC license service on it. I was able to get it to install and the service to start but it will only activate one license at a time even though both services are started. Is it possible to run the PTC license service along side of another application? I found a KB that says yes, but does not explain how. The online instructions are not working as both are conflicting with one another.
Hello, I own a student license and I use a desktop to make my school work at home but i do own a laptop that I take to classes due to it's portability, even being worse than my home desktop, I would love to use Mathcad on both but when I try to activate my license on my laptop it says that the maximum number of license requests were made, if I can't use the software on both my desktop and laptop it gets slightly useless, so I would love to solve this issue
Buen dia comunidad, tengo un problema del grafico de una seccion rectangular donde deseo graficar segun las coordenadas de un matris como se ve en el archivo adjunto, por favor si alguien me pueda oreintar. Version de Mathcad prime V.10.gracias...
Hi, I need help. I don't know why it can't find the variables.I have Mathcad 9.
I define a vector variable X (using a program block) in one part of the MathCad document.The variable is computed correctly and I can access any element Xi later on by the expression Xi :=However when I try to call Xi inside another program block further down, I get "This variable is undefined" error.Would appreciate any suggestions.
Trying to make a plot where the line type is just a dot for every point. This is useful for eye diagrams. The interface behavior is really strange...It won't let you select it. I'm using 10.0.1.0
Hello,In mathcad prime, is there a reason why prime ( using P9) keep losing some images that i pasted in a sheet and replaces some of the images with " Browse for Image?Thanks,Sam
Hi,Find V2 voltage.
I am trying to do geotechnical calculations that I hope to refine.I hope someone can help me with whether it is possible to set up calculations via an input table with different soil layers, which give different stresses, which are used for equilibrium calculations.The simple problem below is solved as a simple hand calculation, but quickly becomes complicated when there are more soil layers, and when the rotation point jumps from different layers. is it possible to do an input tabel with "i" layers and devide all into "n" layers either by index methode ord vector. And then do the rotation calucation by means off "sum" or intregrate with their respektive "hn" I hope anyone can help me in the right direaction, i am not an expext in advanced use off mathcad
Hi, Prime 10.0.0.0 problem, when using the odesolve, I can display the displacement vector, but I can't list the first and second derivatives, when using the prime operator. I can ask for discrete values, but the range variable, only works for the displacement term. I get a message stating that the "calculation is not converging to a solution", although I can plot it. Can anyone assist?,
I need to print and add to word these mathcad calcs with a bunch of warnings saying that the variable is undefined since these are all symbolic calculations:so i am not assigning a value to any of these variables at any point.surprisingly to me when I print, they all come like this: how can I get mathcad not to display these messages and highlights? edit: I went here, and tried selecting/unselecting everything and no luck:
I have a set of commands that sort through a text file to get values, make some of those values a number and then name those values. (See Attached). When I calculate the sheet, I can literally see Prime paint the values into my sheet. Is there a faster way?
