Question
I want to answer all the questions by handwriting.
Referring to the two-dimensional (2D) mesh configurations shown in Figure.4, critically analyze the finite
element mesh division and refining it to obtain accurate solutions by considering the followings:
1. What type of linear two-dimensional element do you recommend discretizing the curved boundary in
Figure.4a? justify your answer.
2. If region in Figure.4b, described a flow problem around the nose of racing car where the flow distribution
values are changing in a rapid manner, suggest an approach to refine the mesh size near the upper edge of
that region, justify your answer.
