Form Closed Triangulation

Note: This tool does not require any setting from the user. Simply select Surface Triangulation Tools and run the command.

It takes the selected surfaces and attempts to form one or multiple closed boundaries, depending on the shape of surfaces.

Before- Multiple disjointed surfaces

After- One closed boundary

A new option has been added when the user clicks on Geometry > Surface Triangulation Tools > Form Closed Triangulation.

This option is only triggered and prompted to the user if more than 1 geometry has been selected.

If the user clicks on Yes, the behaviour of this command is exactly the same as before. The new option is chosen if No is selected.

The new option really is a convenient option. It's there so that if you want N objects processed independently, you don't have to run this command N times (e.g. pick one and form closed triangulation, and repeat for N times).

Example 1: Open the attached project "Combine selected to form closed triangulation" and select both planes and run the command

Yes: Creates a box from the two planes

No: Error is returned as each plane is processed independently. You would get the same result as if you select only one plane and run this command. It is not well defined how a convex hull can be created from a planar object as it has no volume.

Example 2: Open "Form closed triangulation of each object independently" and run this command with both boxes selected

Notice that the two boxes have a missing face. This is where the new option is useful.

No: The two boxes are filled independently. Notice that Form Closed Triangulation is an alternative method to remove any hole on a supposed volume. If you have many of them, it would be a lot easier if you can run this on a batch of objects in one run.

Yes: This behaves the same as before. The two boxes are now created as one.

The following problems have been addressed:

• Divide all, Add to external, Segmenter
• • Improved material assignments to ensure that the new external pieces inherit from the correct parent pieces.
  • Efforts have been made to identify the boundaries of the solid pieces in cases where highly complex and poorly intersected geometries present in the process.
  • Fewer sliver or high aspect ratio pieces
• Volume meshing
• • Improved speed and accuracy in determining the material assignment of solid elements.
  • Feedback with greater detail has been added to inform the user of problems with the geometries.
