I am trying to mesh a model which has a significant size jump in its geometry. Unfortunately, with no success.
Let my try to explain what I mean: there's a model of a colloid mill which works on a rotor-stator principle. Also, there is an extremely small shear gap (0.09 mm) between rotor and stator. The model I try to mesh is the fluid which fills the colloid mill; this narrow gap is also filled.
I have no problems with meshing the whole model except for the gap: Ansys Meshing has big issues in that region. Currently my assembly contains two bodies: rotor and stator with a cut made in the middle of the gap, which means each gap half belongs either to rotor or stator.
The only solution I have found is to slice this gap from the rotor-stator system and somehow mesh it separately, in other words: I will have stator, a part of the gap which belongs to stator, a part of the gap which belongs to rotor, and rotor. Please note, here I am talking about the fluid model, the one I need to put a mesh on. Also, I need to have at least 10 elements in each gap half.
My question is: is there another possible and preferably an easy way to do it?
Thank you in advance!
