I am struggling with the following meshing problem. I am trying to mesh a straigth section of a tube to a conical section of tube. However I cannot get the mesh to connect properly.
The model was made using the geometry-surface-cilinder function for the conical section and extruded the straight sections.
To mesh the model I used the following steps:
- Assigned a plate property to the surfaces (mesh control - attributes on surfaces)
- Set the mesh size on all curves (mesh control - size along curve)
- Meshed all surfaces (mesh - geometry - surface)
Does anyone have a solution for this meshing problem?
Thanks for your help.

This problem is very easy to mesh, your mesh is not coincident because you have two curves, one belonging to each surface: the key is to have only ONE sheet body, not isolated surfaces. You can use use two methods: either create a NonManifold-Add sheet body, or stitch surfaces. My preferred method is always stitching surfaces, the benefits are multiple: the command will do the job of properly have a consistent normal of all surfaces, all surfaces will have the same normal. But NonManifol-Add command simply add all surfaces as they are, not checking normals, then when later you mesh surfaces with shell elements you could have a problem of lack of consistency in shell normals that could cause problems when plotting stress results in TOP/BOTTOM faces, or when applying a pressure load.
In summary, you can do the following:
