   Hi Mosina,

   The function kspaceSecondOrder which is used in this example is based on an exact Green's function solution to the homogeneous wave equation. Unfortunately this means the medium cannot be heterogeneous.

   Similarly, at this stage, we have not implemented initial velocity sources into the first-order simulation functions (kspaceFirstOrder2D, etc). An alternative would be to use a time varying velocity source with a short (but smooth) temporal pulse (e.g., a Gaussian), and then use source.u_mask to define your source distribution.

   Brad.
