2 cards from this section. Quick, good the night before a test.
What is the purpose of discretization in FEM?
Think of how a large puzzle is made easier by dividing it into pieces.
What are shape functions used for in FEM?
They help interpolate values based on nodal information.
What is the primary purpose of the Finite Element Method?
Consider what this method is mainly used for in engineering and physics.
True or False: The mesh in FEM is a collection of elements used to discretize the domain.
Think about how you would define a 'mesh' in terms of its components.
Given a 2D domain with irregular shapes, describe the steps you would take to create a mesh and choose appropriate shape functions.
Think about how the geometry informs your choices.
Explain how changing the degree of polynomial in shape functions might affect the results from a Finite Element problem.
Remember the trade-off between complexity and accuracy.
