how to fix not closed surface and unconnected parts in stl file
 

Hi,

I am beginner to use snappyHexMesh tool. I generate a stl file about barecylinder from solidworks. When I use surfaceCheck to check this file, it shows some issues.

Firstly, the surface is not closed since not all edges connected to two faces. I use admesh to fill these holes.

Secondly, there are seven unconnected parts. And it generates seven .obj files.

Can someone help me on how to fix these issues.

Many thanks.

Charlie

export to step file and make surface mesh using gmsh

Hi, I think you can try 3D builder in the windows store. It's a 1 click repair which works for my case. Note that your output may be shifted after that, if it lies in the negative coordinates.
