This month’s challenge is about tautochrone curves and isochronous curves. They are very similar. Both involve placing an object on the curve and allowing it to slide without friction. With a tautochrone, an object placed at any point on the curve will take the same time to slide to the bottom. With isochronous curves, objects allowed to slide from any part of the curve will have the same period of oscillation. You can think of the tautochrone as “half” of the isochronous curve, as it is only concerned with how long it takes the object to reach the bottom.In this scenario, the “top” of the tautochrone curve is at a height of 10 meters on the left side. The end point is at ( 0, 0 ). (The “top” of the isochronous curve on the other side is 10 meters on the right side.) Design a curve such that an object placed at any point on the curve will take the same time to slide without friction to the end point under the effect of uniform gravity. Examples of three possible solutions from Creo 13.

Hello, I'm having trouble developing a loop that includes break and return statements for buckling analysis. I'm also having trouble generating a combo list for the K values.
I have purchased a new computer because my old computer can not be updated to windows 11. I have Mathcad 14, #15, Mathcad Prime 3.1 on my old computer. I want to put them on my new computer and my question is whether I can copy the files to a usb drive and put them onto my new computer? Or cand is download the from and old download file? Or do I new to get a new download from PTC?Your assistance would be greatly appreciated.
I need to evaluate anchored walls, according to FHWA Circular 10, for various strata, but I've had problems with the definition of a vector i. This new version of Circular 11 changes the definition of a vector, so could you help me with this problem?Regards.For loop and return for a vector i
We run FLEXnet on our company license server for Mathcad licenses. Currently on version 12. Our Mathcad license file has both permanent and subscription licenses of Mathcad Prime (and 15) in it. When a user runs Mathcad, the server first assigns a license from the permanent pool. If that pool fills up then it assigns a license from the subscription pool. The problem is when a user receives a license from the permanent pool, the license type shown within their Mathcad software says Home Use when it should say something like Commercial. This results in certain calculations being inaccessible and causing errors in their worksheet. But if a user receives a license from the subscription pool, the license type is shown as Subscription which should be fine.I would like to know why our Mathcad license server is serving us Home Use licenses instead of the commercial licenses we paid for, and how do we fix this?

Have just paid for a licence to upgrade from MathCad Prime Express 12.0.0.0 to the full Prime version, hopefully 12.0.0.1. Following "Options|Get Licence" I have encountered a prompt asking for my product code. Where can I find this? Do I need to log in to the Fullfillment portal? Does it use the same general ptc account? It didn't recognise mine. When looking for help I am told I don't have access permission and haven't paid for that level of support. Elsewhere it says I have "Gold" level support. I an angry that you have now pointed me to a public forum where I can't post useful identification data. What a horrible mess. Can anyone help me get into contact with someone at PTC?
Hello,I am new to developing custom functions for Mathcad Prime.I already managed to create a working custom function in C, but I still cannot understand how to do the same in C++.To be honest, I do not understand the internal structure of Visual Studio C++ projects yet. I am learning step by step and using AI to help me understand the code and project structure.My goal is to move large engineering calculations from Mathcad into C++ DLL libraries. I hope to use AI to help convert my Mathcad algorithms into C++, but first I need to understand how a working C++ custom function project is organized.At the moment I cannot even create a very simple function like:int add(int a, int b){ return a + b;}I am not asking anyone to write my project for me.I would simply like to have a minimal Visual Studio C++ project that builds into a DLL and is recognized by Mathcad Prime. Even a project containing only one simple function would be enough.Once I have one working example, I believe I will be a
Hi, as you can seeat the bottom of the picture, when evaluting the function “Iresonance”, instead of replacing the variable with the actual, it gives “function” in the result, but the function “wresonace” is already defined. How to subtitute it? Thanks
Hi There ,I have two functions are exactly the same but in two different sheet in the first sheet . it works perfectly and I’m getting the expected answers for f2In the second sheet it doesn't work and I suspect the reason is M has different arrays . How can I fix this function : the error says : This array index is invalid. The index must be an integer, not less than ORIGIN, and not greater than the last element."I can’t attached simplified sheet even in zip file. I hope you can help Thanks in advance , Yusra
Hi, I’m just trying to get the real and imaginary part from a complex number, but the result is just not right.
I can not contact a support department "access denied" to get a new licence file to install my Mathcad 15 on a new computer. Could you help me. I am desperate ! J.P. Collette jpcollette@walopt.com
Hi there , How can I work in Mathcad faster. it freezes when I use large data I have to use loop functions , however , it took so much time and doesn't calculate I have to close it and open it again and still doesn’t work Thanks, Yusra
I would like to use the result of a quadratic function for another mathematical operation. Example: F(x)=4x^2+x-3 gives the results -1.0 and 0.75. I would like to use the value 0.75 for another operation. Please give me some tips on how to write this in Mathcad.
Hi There , I always face this error and I don’t know how to solve this . I need to find the difference between 2 levels in same z which has 4 rows like it do the same calculation for each row separately Than I have to find the average and minimum value for this results I attached simpler mathcad in zip file
Hi. I am trying to use an advanced list box to select a beam section from the first column in a matrix that I can then use to lookup related properties further on in my calc sheet. The problem I have is that the selection does not get parsed to the output variable. Any help with this would be appreciated, I can’t seem to find anything useful online, but I am clearly missing some detail.Here is the list box code and MathCAD file attached. // TODO: Add your initialization code herefunction ListBoxEvent_Start(Inputs, Outputs) { // TODO: Add your code here};function ListBoxEvent_Exec(Inputs, Outputs) { // 1. Clear the list box contents FIRST to reset it ListBox.ResetContent(); var options = Inputs[0].Value; // 2. Loop through and add the strings for(var i=0; i < options.length; i++) { ListBox.AddString(options[i]); } // 3. Set your output Outputs[0].Value = options[ListBox.CurSel()]; //Outputs[0].Value = ListBox.get_text(ListBox.CurSel());};function ListBoxEvent_Stop(Inputs,
Hi community,I’m coping a program to make tables but get errors?What's wrong?Regards,CarlosRomero PD. This routine can be used with either vectors or your beloved ranges as arguments. First we create a function which tables a function with three arguments, so that the result is a nested array consisting of a vector of matrizes. Ever of those matrices shows the function values whith constant third argument z and x as rows and y as columns.
Hi Everyone I’m doing the same calculation in two different sheets , but I get errors in the another one although they are the same . why is that ? thanks Yusra
pls i need this thing
Hello Could you please assist us activating MathCad 14 license. If not possible, I also have a license file from a PC that need to be moved to another computer. Best regards,
Dear all, Hope everyone is doing well. I am using Mathcad Prime 8 and I am trying to find a way to convert a pdf (originally a mathcad file) into a mathcad file (e.g. mcdx). There are formula equations in that file and so far when I try adding the file into Mathcad, the formulas are not recognized. Is there any way to do this? Best regards,Vich
It seems that my Mathcad version I have just downloaded Is Mathcad express Prime and not the Mathcad prime. Please check.
How can I make sure that e_max is added correctly … non of them has units , but still getting this error Thanks Yusra
