Version 1.2 - Transonic correction and analytical gradients
This version mainly features a transonic solver and analytical pressure derivatives.
Changes
Add transonic correction
Add analytical gradients
Add feature to deform the body
Fix calculation of motion-induced velocity and unsteady pressure
Refactor APIs and utilities
Notes
Transonic correction
The unsteady pressure solution can now be corrected by higher-fidelity data (typically obtained from CFD) to include transonic and viscous effects. Analytical gradients
Although CoDiPack works well, its memory footprint is too large for practical unsteady cases (see #6). Analytical pressure and aerodynamic forces gradients have therefore been implemented so that flutter constrained optimization can be performed within a reasonable computational time. Body deformation
The body nodes can now be set to new positions for aeroelastic and optimization purposes. Formulation fixes
The calculation of the surface velocity induced by a rigid pitching motion has been corrected to use original instead of compressible coordinates. Additionally, a mistake in the calculation of the unsteady pressure coefficient has been fixed. Refactoring
The default values in the API have been refactored. The slicing utility now also outputs z-coordinates.
