WebIn this study, we address the relationship between venation pattern and wing flexibility by measuring the flexural stiffness of wings (in both the spanwise and chordwise directions) and quantifying wing venation in 16 insect species from six orders. WebApr 25, 2024 · a) spanwise is from root to tip, generally following the quarter-chord line, and chordwise is the direction that gives the shortest distance from leading edge to trailing …
WebAs said in the previous section, the ADI scheme leads to solving an implicit tridiagonal system in each direction by using the iterative Choleski algorithm. The periodicity in the spanwise direction (see section 3) leads to iterate from K=1 to K=NZ and then from K=NZ to K=1 and this can’t be done in a parallel way.
