2D antisymmetric orientation in the y-axis?
 

Hi,

I'm trying to model a droplet of water falling into a beaker with a heated base. It's a 2D model, so I'm looking at a cross section. I've used an antisymmetric model, using the y-axis as a the mirror axis. The model is running, albeit very slowly. Is this something to do with me not using the x-axis as the axis of rotation?

Thanks in advance for any help!

I think the slow running is a separate problem.

But you should fix your configuration to use the x-axis as the axissymmetric axis.
