add LDDRK4 support to SPECFEM3D #403

Closed komatits closed 9 years ago

komatits commented 9 years ago

The LDDRK4-6 high-order (more expensive, but much more accurate) time scheme is currently implemented in SPECFEM3D_GLOBE but not in SPECFEM3D. We should thus cut and paste it from there at some point.

This will be much easier once we make SPECFEM3D_GLOBE and SPECFEM3D much more similar, see https://github.com/geodynamics/specfem3d_globe/issues/26 .

Zhinan @xiezhinan is going to implement it.
