Question 1

What is the primary goal of verification in finite element analysis?

  • To ensure results match experimental data
  • To confirm models solve equations correctly
  • To establish project milestones

💡 Hint: Think about what it means for a model to be accurate.

Question 2

True or False: Validation ensures a model produces results that are not influenced by the mesh size used in the simulation.

  • True
  • False

💡 Hint: Consider the differences between validation and verification.

Challenge Problems

Push your limits with challenges.

Question 1

A mechanical engineer is tasked with designing a new bridge. They have run simulations using FEA but have not performed a mesh independence study. What risks might this pose to the bridge's safety?

💡 Hint: Consider how mesh size can influence the accuracy of model predictions.

Question 2

After testing a bridge design with FEA, an engineer finds their model's predictions differ significantly from measurements taken from a physical prototype. What steps should the engineer take next?

💡 Hint: Think about what factors could differ between simulation and reality.
