+Hi Dimitri,
+
+Sorry for delay! I finally had time to work on this.
+
+Attached complete mesh files and TRELIS/CUBIT files. Mesh quality is
+now improved from scaled jacobian 1.083e-02 to
+ 6.063e-02.  Those files are ready to run with specfem2d but still
+missing are Par_file and SOURCE files. As Yann previously mentioned,
+material properties file needs to be decoded! I did not delete or
+merge any surfaces, therefore the original material properties file
+should work as is once decoded to specfem2d format.
+
+I put the origin on the top left corner, define the absorbing
+boundaries on left, right and bottom, and free surface on top.
+
+Please note that the .trelis and .cub files are not compatible with
+old Cubit version. Since smoothing/blending/chamferring sharp corners
+is a manual process, creating a Journal file is unrealistic.
+
+Let me know if you find any issue/s.
+
+Best,
+Hom Nath
