Inkjet and axis-symmetry
 

Dear Sirs,
I have to simulate a drop formation in a microfluidic inkjet system.
I use cylindrical coordinate and cylindrical mesh; when I set 30 degree of mesh axis-symmetry is automatic? Or is necessary to set-up something other?
And if I set 20 or 40 degree is the same?
Thank you.

For an axisymmetric problem, set any angle (preferable less than 90 degrees), one cell in the azimuthal direction and symmetry BC at front and back mesh boundaries. 20, 30 or 40 degrees should make no difference.

If you leave no input for all these parameters, they will default to axisymmetric setup with 30 degrees.
