- •
Simultaneous shape optimization of the curved surface and attached holes is modeled.
- •
A moving bounds strategy is carried out to determine the parametric reference domain.
- •
An arc-length rule is proposed to calculate allowable bounds of the reference domain.
- •
Design variables related to the hole shape are normalized to obtain fixed bounds.
