+- suggestion 40:
+----------------
+Currently, the way of PML implemented for acoustic/solid simulation is memory consuming. we should
+in future reduce the memory usage in following way:
+1: replace the rmass_acoustic_interface(nglob_acoustic)  with rmass_acoustic_interface(nglob_acoustic_solid_interface)
+2: replace the potential_dot_dot_acoustic_interface(nglob_acoustic)  with potential_dot_dot_acoustic_interface(nglob_acoustic_solid_interface)
+where nglob_acoustic denotes the whole point set inside acoustic region, nglob_acoustic_solid_interface denotes the point set on acoustic_solid_interface
