General Information about SCUDEM
SCUDEM — SIMIODE Challenge Using Differential Equations Modeling is a 3-student group modeling challenge that runs over multiple days culminating in a strict limit 10 minute video which is reviewed by at least 3 judges.
Teams choose one of the Challenge Problems provided in the areas of
- physics/engineering,
- chemistry/life sciences,
- social sciences,
and develop a model using differential or difference equations and a presentation.
Teams and Coaches may meet remotely or in person. Student challengers must work with their team without other animate assistance, including from their coach, during the challenge period. Team submissions will be judged Outstanding, Meritorious, or Successful.
Read the Complete Rules for details of the challenge.
See problem statements and results for past events in our wiki. SIMIODE's YouTube channel features presentations of past Outstanding Award recipients.
As a Judge, you have the opportunity to help students develop their mathematical modeling skills. If you'd like to support our teams' intellectual growth, as well as help them to network, then please volunteer as a Judge for SCUDEM X 2025
Consider volunteering as a Coach for SCUDEM X 2025. Plan to start working with your team before SCUDEM begins in order to help prepare these energetic students for the modeling experience.
MathWorks software information
We are pleased to offer all SCUDEM X 2025 participants (team members and coaches) a complimentary MATLAB & Simulink license. For registered SCUDEM X 2025 participants you can visit this webpage and press "Request Software" to acquire your license. MathWorks customer services will send you a license key within 48 hours.
