Rotated 1D Problem
As shown in the picture, a 1D problem defined along
the direction which has an non-zero angle with respect
with respect to x-direction. Computation is conducted in
x-y coordinate (in region OABC ).The physical variables
in x-y coordinate are obtained from those in the new
coordinate, and vice versa. This is often employed to
test numerical methods for keeping constraint of for 2D
