3D crack modeling using CTMOPT macro in ANSYS

Hello Everybody..

I am MS student in University of cincinnati, Oh, USA. I am working on
fractures in thin film and for  that i need to model 3D cracks. Problem
is i cant just use extrude comand becuase, crack is not throughout tht
length of the film ( So i cant use th eapproch mentioned above). there
is CTMOPT macro in ansys which allows to desgin meshing at the crack
tip. I am struggling with the ewxplanation given there. If anybody has
detail information in how to implelment this macro, please let me
know. 

Thanknig you,

hi 

i am doing my PhD in  "smart composites"

i am working on piezoelectric composite materails... 
i will be greatful to you if anyone can suggest me  how to model the piezoelectric materials in ANSYS.i am having some doubts in meshing and giving the voltage input to ANSYS.

if i directly glue actuator to the beam using volume glue  then i am getting problem while meshing volume as "invalid topology for mapped brick mesh". how can i glue two volumes in ansys and avoid the problem in meshing???

expecting a response ....
