Vertical Manifold

[sidnigam]

Created 3 stls -- 1 for the outlet (simple cylinder), 1 for the box with a cylindrical hole, 1 for the vertical manifold.

copy pasted them into 1 stl, and snappy compiles but mesh isn't right - it's hollow and doesn't have the vertical manifold cylinder with holes

Judging by the STL rendering on GitHub, it looks like the outlet face of the manifold (inside the box), might be a "solid" circular surface.

[sidnigam]

better now with the outlet and inlet, but I suspect the small cylinders (supposed to be holes) might be too small for the mesh to work properly?

[sidnigam]

based on the branch sidmanifold water.stl file

Maybe you need to refine near those edges and surfaces more in snappyHexMeshDict or refine the background mesh a little.

[sidnigam]

i tried changing the refinement to 4 4 level for it, and doing searchable cylinders and searchable box, but no luck

[petebachant]

Hmm, is the point in mesh in snappyHexMeshDict actually set to be inside the geometry?

[sidnigam]

yeah, i think the problem is when snappy is running, it moves some points -

Calculating patchDisplacement as distance to nearest surface point ... Wanted displacement : average:0.00042282558 min:1.8461472e-05 max:0.0010438124 Calculated surface displacement in = 0 s

Figured it out! :dancer: :smile:
