Different elements sizes

Postby albasha » Sun Jan 20, 2019 9:48 pm

Hi there,
I am creating a model with different parts. I am trying to mesh each part with different elements sizes, however when I am meshing one part with different elements sizes, the other adjacent parts also affected by the new elements sizes. Kindly, could you let me know the possibility of defining different elements sizes for each part without affecting the adjacent parts?
Kind regards

If the parts are connected by some shared line then by continuity one part affects the other part!!

If they are non connected at all then maybe are affected by the 'Automatic correct sizes' (that will decrease big sizes assigned close to small sizes)
To do it go to Utilities->Preferences... Meshing->General, try 'Automatic correct sizes' to None, but then you must assign sized accurately to be able to generate a mesh.

If your parts are connected but your physics really doesn't require this continuity you can try to modify the geometry with the tool
Geometry->Edit->Uncollapse
in order to create a duplication of entities for each part.

You can assign to each geometric entity the approximated mesh size that do you want, when the mesh will be created
