Hi Sharmita,
the issue is quite simple and there are many ways, how
to do it in Ansys. You simply create 2 areas, one
smaller (60 x 60) and one overlaping bigger. There is
a function of "overlap" or something like that in
"operate" menu. THat would create new area 100x 100 um
with cut of hole of 60 x 60 but that would be glued to
the internal square. After that you define a
multilayer under real constant and there would be
either two layer inside or two layers outside, choise
is yours. If you are interested, send me an email and
I will send you a script file. That is trivial.

HI all,

I am modeling a pressure sensor in Ansys. The
dimension of the membrane
is
100*100 micrometer.  I have used shell 93 for meshing.
Now I need to
model
this membrane by adding a layer of another material in
an area of 60*60
micrometer on top. I have tried many Boolean
operations in Ansys but
unsuccessfully. Can somebody suggest a way of doing
this?
Thanking you in anticipation

Regards
Sharmita
