ELEMENTS AND MESHING

Question 1

What is the DIFFERENCE BETWEEN FIRST AND SECOND ORDER ANALYSIS?

Answer 1

• The 1st order is only calculating deformation at the vertices while the 2nd order also calculates deformation at the midpoint of the element’s edges
• 2nd order is

Question 2

What is the difference between H-TYPE and P-TYPE ELEMENTS?

Answer 2

H-Type elements are made by decreasing the element size and increasing the number of elements while keeping the polynomial order the same.

P-Type elements are made by increasing the polynomial order while keeping the same number of elements.

Question 3

What MUST BE THE SMAE FOR TWO MESHES TO BE COMPATIBLE?

Answer 3

They must have the same polynomial order
