Hi
Yes, you are right, that's a good idea to view the mode profiles at different x position. BTW, I have solved the mesh multiplier issue.
I can first add FDE and then select the mesh to set the multiplier setting.

addmesh;set("x min",-L_buffer_in);
set("x max",L1+L2+L_buffer);
set("y",0);
set("y span",Wwindow);
set("z min",-2*tBOX);
set("z max",-tBOX);
set("override x mesh",false);
set("override y mesh",false);
set("override z mesh",true);
set("name","Si substrate override");
addfde;
select("Si substrate override");
set("set mesh multiplier",true);
set("z mesh multiplier",4);
