   I am simulating a 1D problem where the mass density of the fluid changes by several orders of magnitude between the beginning and the end of propagation from 1.2 to 10^-12 over 150 wavelengths. When doing so the code diverges (whether I use linear/nonlinear, attenuating/lossless propagation). When I impose such changes (with several orders of magnitude) to the wave velocity, the code runs without a problem. Did you ever encounter this problem? Any hint on why the code would diverge on big density changes would be useful.
   Thanks!
