Axisymmetric mesh in ANSYS Workbench

Hi everybody,

I am trying to investigate a biaxial
membrane inflation experiment of human aortic tissue by the help of
ANSYS Workbench. Before examining the actual anisotropic tissue I
however am trying to create a model based upon a hyperelastic, but still
isotropic, material. I have chosen the pre-listed neoprene rubber in
ANSYS Workbench.

However, my results sreem to be a bit
differing from the "actual truth" where I expect an axisymmetrically
distributed stress when applying the pressure on my circular specimen. I
was after this recommended by my supervisor to make an axisymmetric
mesh on my circular model, however I am not sure how to create such a
mesh in ANSYS Workbench?

 Do you know, and can you help me to make
an axisymmetric mesh on my circular sample? 

 Thanks for your
help.
