Question

In local mesh refinement, if very small elements are placed adjacent to very large ones, then the mesh becomes unacceptable.

(a) True

(b) False

I got this question in homework.

I'd like to ask this question from Modelling Considerations in section Interpolation Functions, Numerical Integration and Modelling Considerations of Finite Element Method

Answer 1

Right answer is (a) True

Best explanation: Generally, local mesh refinements should be such that very small elements are not placed adjacent to very large ones. A mesh can be coarse (i.e., have few elements) or refined (i.e., have many elements), and may consist of one or more orders and types of elements (e.g., linear and quadratic, triangular and quadrilateral).
