[CIG-SEISMO] variable mesh spacing

[Nicholas Mancinelli]

Hi,

I’m trying to use SPECFEM2D to simulate elastic wave propagation in the crust and lithosphere while including effects from reverberations in the water column.  Can you point me to a good method to generate a fine mesh (for the water column) atop a coarser mesh (for the lithosphere)?  It does not appear that the built-in (i.e., internal) mesher is capable of generating mesh layers with varying numbers of elements in the x-direction.

Thanks in advance for any advice!

Nick
