Used for

The body outline, sound-hole apertures and cavity of the six earlier-design studies, and the body and neck basis of the Auxetivarius preview.

Changes

Earlier-design studies: the body outline and apertures were used to build a reduced-order structural and acoustic model. Neck position, depth and cross-sections are idealized. Top-skin thickness, back thickness, cavity depth and port size were varied across six calculated studies.

Auxetivarius preview: rod-free neck; modified body with a flat closed back, auxetic cells and new assembly components; simplified setup parts; display mesh coordinates rounded.
