There are four options for how the healing should be done:

Automatic

This will first attempt Natural Healing, including an additional internal method that sometimes allows a smooth ‘natural’ healing when the standard Natural Healing fails. Then, if both of those fail, Patch Healing is attempted. An error will only be reported if none of these methods succeed. This is the default for new features.

Natural Healing

For this option select the faces such that upon removing these groups, the surrounding geometry can extend naturally to cover the wound(s) left by the removed faces. If a suitable extension cannot be determined, the feature will report an error stating that it cannot heal the wound. This is the default for features created prior to Ansys DesignModeler 11.0.

Patch Healing

This method takes the edges surrounding the selected faces and tries to create a single face to cover the region.

No Healing

This is a special option for dealing with Surface bodies. It allows for the deletion of faces from surface bodies without any healing. This can be useful for cleaning up some models. This can result in multiple surface bodies if deleting the selected faces leaves faces that are no longer connected. If faces from Solid bodies are selected with this option, it is treated like "Automatic" for them.

Example 85: Forms of Healing Illustrated

Suppose this hole is to be deleted from this model. Select these two faces.

Using Automatic or Natural Healing results in the following:

Using Patch Healing the result would be as follows:

For surface bodies the No Healing option may be applied:

Deleting with the No Healing option yields this result:
