SkyCiv Science Olympiad 2020 Competition App

Design and test your Boomilever structures, using the Science Olympiad App

SkyCiv has partnered with Science Olympiad to help digitize the Science Olympiad competition for the 2020-21 season! The app sits inside SkyCiv Structural 3D to simulate the competition testing. Not sure how to model or design your boomilever? See this article on how to model a boomilever in SkyCiv with video and a step-by-step guide.

The SkyCiv Science Olympiad App will auto-analyze and test your Boomilever based on the competition criteria. Instead of physically building the model and testing it under the load of a bucket of sand, the App will apply the load gradually and test it based on Finite Element Analysis. Key results are then displayed, with some insight into why the structure is failing.

The app will also test the rules and guidelines of the competition, including the load distance, structure width, material usage and more (see below).

Getting Started

After signing up for a Science Olympiad Account (or SkyCiv Student Account), login and visit your account settings:

Under Add-ons and Integrations, you should see a Science Olympiad app. Switch that on and click Save Settings. Once this is done, visit SkyCiv Structural 3D and you should see the Science Olympiad app under Add-ons in the top navigation bar:

Clicking this will launch the App and allow you to start testing your model. Not sure how to model or design your boomilever? See this article on how to model a boomilever in SkyCiv with video and a step by step guide.

Building Requirements

Each individual event, competition, or division may have its own set of building requirements, including contact depth, contact width, and minimum loading distance for the wall. However, there are some consistent building requirements for the app, that should be met regardless of what level of competition you’re in.

Area Loading

Your area load should be a Two-Way -60 kPa force over a 5x5cm square. Area load nodes (Corner Node IDs input) should be entered in a clockwise or anti-clockwise direction. Here is an example of a correctly applied area load:

Also note the variance is 0.00% this is also required for the successful solve of your Boomilever.

Building Direction

You will also need to build your boomilever in the X-direction (not the Z-direction). Again, here is an example of a correctly built Boomilever:

Results and Scoring

Main Results

The app will run through about a 100 iterations to calculate the load at which the structure fails (if in fact it fails). During this process, it will calculate the following results:

  • Max Stress: this is the stress that your members are undergoing under the peak load. If your structure is failing due to stress (stress exceeding 7MPa) then this result will hover under that stress limit.
  • Structure Weight: the weight of the structure. This value is used as the denominator in the calculation of the performance score. So the lower this value, the higher your score.
  • Deflection Check: does your structure deflect to a point where it comes in contact with the back wall?
  • Structure Capacity: how much weight did your structure hold (excludes self-weight)?
  • Performance Score: This is simply calculated as structure capacity/structure weight and is the score that is submitted for your team

Criteria Checks

In the background, the app will be checking the following:

  • What is the distance of the point load to the wall?
  • What is the width of the structure?
  • Materials used were one of 3 allowable Balsa Wood grades
  • Plus more

These results will be submitted with your overall score to ensure the rules and guidelines of the competition are met.

Competition Mode

On your designated event day, users will toggle on the Competition Mode in the top right corner. Important: Toggling on this switch will delete your model, remove some of the functionality in S3D and limit the number of solves for 48 hours. Please do not toggle this on unless it is your competition/event day. The blue Submit Score button will also become available where you can submit your final score via the below form.

Submitting your Score

When you are happy with your design you can submit it – but careful you can only do this once! This will submit your score to Science Olympiad to compete against other teams. You’ll need your Event ID and team ID which you should have from your state director.

In order to submit your score, you will have to be in Competition Mode. From there, you will need to rebuild your model from scratch and test it to get a score. Once you’re happy with your score, click Submit Last Score and fill out the submission form. This will confirm your score, and allow you to select an event name from a dropdown list:

Your score will then be lodged in CSV format for the event organizers to download from their custom links.
