Question

FIGURE E7.2. Transition meshing for Exercise 7.2 EXERCISE 7.2 [D:15] Part of a two-dimensional FE mesh has been set up as indicated in Figure E7.2 Region ABCD is still unmeshed. Draw a transition mesh within that region that correctly merges with the regular grids shown, uses 4-node quadrilateral elements (quadrilaterals with comer nodes only), and avoid.s triangles. Note: There are several (equally acceptable) solutions.

Answer 1
