[CIG-SEISMO] SPECFEM3D Tomography Model

[Dimitri Komatitsch]

Dear Yingzi,

That is not possible because a spectral element needs to be either 
entirely acoustic or entirely elastic (since acoustic-elastic coupling 
occurs at interfaces between elements but never inside a given element).

Best wishes,
Dimitri.
