comment Sweeby Lax-Wendroff flux
Ok found the misunderstanding... we want the upwind flux to appear in the scheme, and this will depend on the sign of the velocity. Making this appear in the lax-Wendroff formula changes the definition of the flux after little algebra.

comment solution of multidimensional PDE
For instance in cims.nyu.edu/~corona/hw/PDE%20NOTES%20Shatah%2009.pdf, they assume the coefficients are non zero, but in my case y, g1, z and x can be zero

comment solution of multidimensional PDE
I'm not really aware of this method, I've found many references on the web for "method of characteristics" but not specific enough for me to understand what to do. Despite, why are you talking about "initial" condition and not "boundary" condition?
