Back in 2024 I presented a little introduction to simulation at PyCon.
Introduction to Simulation
And in that presentation I asked a fundamental physics question.
If a heavy cat sits on a bridge of ice. Does that bridge break?
But in that situation everything was simply two dimensional (to save time). But what if it wasn't?
Suppose we were to make a horizontal lattice of beams of ice, each just 0.1 m long. What is the smallest number of ice beams needed to hold up the cat? And in what arrangement?
The Geometry
- 1 m x 1 m square bath
- Edges are fixed in space
- The cat sits at its centre at the coordinate (0.5, 0.5) (or (0,0) if you'd prefer)
- The cat weighs 6 kg
- Ice beams have
- Square cross-sections 0.01 m x 0.01 m
- Length 0.1 m
- Density 917 Kg/m^3
- Young's Modulus 10GPa
- Yield Strength 6 MPa
- Poisson's ratio 0.33
The best answer will get featured on the developer portal in an upcoming blog post and a shout out on LinkedIn!
Make sure to show how you solved the problem using PyMAPDL or PyMechanical if you can!
