problem 3d scroll - no remeshing -

*** I am a student who is writing her thesis on a scroll-type expander volumetric and I encountered some problems using the dynamic mesh fluent in package ansys 13.
1) I used to build the tetra mesh from ICEM, correct? or should I use a mesh with hexahedral?
2) the UDF is right? -->
DEFINE_CG_MOTION(wall_pale_mobili, dt, cg_vel, cg_omega, time, dtime)
real freq = 0.13695;
real amp = 0.0067;
real ampy = -0.0067;
velx = amp*sin(omega*time);
vely = ampy*cos(omega*time);
cg_vel = velx; /* x-velocity*/
cg_vel = vely; /* y-velocity*/
cg_vel = 0.0;
NV_S (cg_omega, =, 0.0); /* no angular motion */
3) I used remeshing local cell and 2.5 D. .. what do I need to concentrate?
4) dynamic mesh in the preview, you see only smoothing and remeshing, why?
thank you very much
