Mathcad Community Challenge Index / Guidelines

PTC is pleased to announce the Mathcad Community Challenge, a bimonthly event where we’ll post an open-ended challenge for you to solve using PTC Mathcad Prime. Feel free to collaborate with other users and their worksheets by attaching your worksheet to your posts here.
 

In general, at the start of every other month, we’ll post a new thread with the challenge. You can post in that thread throughout the month with contributions. Around the middle of the next month, PTC and our affiliates will go through the contributions and create a resolution to it in the form of a Mathcad.com blog article discussing your interesting approaches to the problem. Then, we’ll post a new challenge at the start of the next month.

We hope you enjoy this challenge!
 

Some rules and guidelines:

  • Your contributions will be monitored by PTC and PTC-affiliated parties. We may use them in marketing material, including in post-challenge discussions hosted on PTC properties like Mathcad.com and PTC.com
  • Use PTC Mathcad’s documentation features in your contributions so everyone can follow along
  • Use units whenever possible
  • Only .mcdx (Mathcad Prime) worksheets will be eligible for participation.
  • It is greatly preferred to not use external custom function .dlls. While it's cool to show off Mathcad Prime's custom function feature, relying on them to solve challenges defeats the purpose that these are meant to be solved using Mathcad
  • Humans should create your solution, not an artificially intelligent (AI) bot. Show off your skills as an engineer or mathematician!

Look out for posts by Dave Martin, a former Mathcad instructor, author of Mathcad books, contributor to our PTC.com blogs, and occasional contributor to the Mathcad and Creo YouTube channels. He also runs the popular “Creo Parametric” YouTube channel. Learn more about Dave here.

Ah, sorry for the confusion!

(But also thank you for your interest!)

Definitely post your solutions to the individual challenge threads!

 

 

So in March, there'll be another problem in another thread and this thread will link off to that. This is more of a central "hub" post.
