You can use this repair feature to remove small faces from the model.
Fault Finding Criteria
DesignModeler uses the area of the face as the criteria to search for small faces in the model. A face whose area lies between the minimum and maximum limit is determined to be a fault. If all faces of a body are chosen as faults, then the entire body will be deleted.
Methods Available
Automatic: First, a Face Merge method is used to fix the fault. The small face is merged with one of the adjacent faces. If this method fails, an alternative approach is used to fix the small face.
Face Merge: The small face will be merged with one or more adjacent faces. Ansys DesignModeler automatically suggests one adjacent face for merging. You can change this selection if required. However, a face needs to be specified for the operation to be successful. Note, while manually selecting faces for the face merge operation, you can select only those faces that use the vertices of the face or the adjacent to the face.
Note: In case of Repair Faces, Ansys DesignModeler suggests Automatic method for fixing all the faults. You can change the repair method to Face Merge if desired.
Example 93: Using Repair Faces Function
As an example of Repair Faces operation, consider the figure below. If you search the fault entities with default settings then two faults will be listed. For both the faults, the Automatic method is suggested
Results are shown in the figure below after Generate.
