Finite Element Analysis

Question 1

What are nodes? State their significance in FEA

Answer 1

Calculations are done at each node and these results at each node approximate the result which indicate the effect of loading/condition of each element

Question 2

What are elements? State their significance in FEA

Answer 2

Elements are the area between the nodes in a model. They can be 1D, 2D or 3D. Allow complex geometries, varying material properties and complex loading scenarios to be analysed

Question 3

Matrix equation that FEA calculates based on each node?

Answer 3

Question 4

At _______ we solve for ________ when using Thermal conduction FEA?

Answer 4

Temperature

Question 5

At _______ we solve for ________ when using linear elastic structural FEA?

Answer 5

Displacement

Question 6

What are the four requirements of a physical model?

Answer 6

Physics model to analyse

Material Properties

Meshing

Loads and Boundary conditions

Question 7

cons to using lots and lots of small elements? (three)

Answer 7

More equations = more time = larger data files = need to be careful applying to 3D models
