To repair objects, from the Geometry toolbar, Defeaturing and Repair () menu, select Repair (). You can also right-click the Geometry node and select the same option from the context menu.

Select the objects to repair in the Graphics window. They appear in the Input objects list.

The software tries to repair defects and remove details smaller than the Absolute repair tolerance. More precisely:

Select the option Simplify curves and surfaces to also simplify within the Absolute repair tolerance the underlying curve and surface manifolds of the geometric entities. Repairing objects with this option may improve both the performance and reliability of geometric operations on some imported geometry, for example it may help in some cases when Boolean operations on the imported objects fail. Simplification means that the manifolds are converted where possible to analytical form: linear, circular, and elliptical curves; and planar, spherical, cylindrical, conical, and toroidal surfaces. Manifolds that are converted are B-spline curves and surfaces, or certain surfaces generated by operations such as sweeping, revolving, and filleting.

Select the Repair face-to-face inconsistencies in solids check box to try to repair solid objects with this fault reported by Import, Check, or Repair features.

When the option Check resulting objects is selected the repaired objects are checked for remaining problems. Warning nodes appear with details about the detected problems, if any. Use the Zoom to Selection button next to the Entities list in a warning node to locate the problematic edges or faces. For information on geometry problems see the Check feature.

If you want to make the resulting entities contribute to a cumulative selection, select a cumulative selection from the Contribute to list (the default, None, gives no contribution), or click the New button to create a new cumulative selection (see Cumulative Selections in the COMSOL Multiphysics Reference Manual).

Select the Resulting objects selection check box to create predefined selections (for all levels — objects, domains, boundaries, edges, and points — that are applicable) in subsequent nodes in the geometry sequence. To also make all or one of the types of resulting entities (domains, boundaries, edges, and points) that the resulting objects consist of available as selections in all applicable selection lists (in physics and materials settings, for example), choose an option from the Show in physics list: All levels, Domain selection, Boundary selection, Edge selection, or Point selection. The default is Domain selection, which is suitable for use with materials and physics defined in domains. For use with a boundary condition, for example, choose Boundary selection. These selections do not appear as separate selection nodes in the model tree. Select Off to not make any selection available outside of the geometry sequence.

From the Construction geometry list choose On to make the resulting objects available only in the feature’s geometry sequence. The default option Inherit from input means that the resulting objects become construction geometry if all input objects are construction geometry. Choose Off to never output construction geometry objects. For more information see Construction Geometry in the COMSOL Multiphysics Reference Manual.
