Your task is to modify the code to implement elliptically-anisotropic wave propagation<br />
according to equation<br />
∂ 2 P<br />
∂t 2 = V 2<br />
1 (x) ∂2 P<br />
∂x 2 1<br />
+ V 2<br />
2 (x) ∂2 P<br />
∂x 2 2<br />
+ F (x, t) (17)<br />
You can test your implementation using a constant velocity example shown in Figure<br />
2.<br />
Figure 2: Wavefield snapshot for<br />
propagation from a point-source<br />
in a homogeneous medium. Modify<br />
the code to make wave propagation<br />
anisotropic.<br />
1. Change directory to geo384w/hw1/code<br />
2. Run<br />
scons wave.vpl<br />
to compile and run the program and to observe a propagating wave on your<br />
screen.<br />
3. Open the file wave.c in your favorite editor and modify it to implement the<br />
wave operator from equation (17).<br />
4. Run
