Hello,

I am trying to study droplet generation using 3D geometry.

I have used triangular mesh with a maximum element size of 7um and the result obtained is good. But whenever I try to decrease the element size(increase no of elements) to less than 7 um, it gives me an error saying "Nonlinear solver didn't converge"(also attached a photo).

What can be the possible solution for this?

Thank you
