Tucan 4.0

This version contains a complete new set of tools to model and analyze propellers.

• A new Surface derived class can generate the propeller mesh from parametric data (diameter, twist, chord, pitch, etc.) .
• The propeller model is converted automatically into a proper calculation model (set of lattices, wakes, etc.).
• The console includes a batch command to run a complete propeller analysis (Ct, Cp and Eta as functions of J).
• The rotation of the flow has been reviewed (it was not suitable for large rotations). This affects the free flight module in some degree.

Be aware that this new feature may contain bugs.

Tucan 3.3

This version contains important corrections in the structural model (affecting the modes in some cases).
There are no new features compared to the previous version.

Tucan 3.2

Correction and new functions

Tucan 3.0

This release:

• A new free flight simulator has been included.
• The aeroelastic module has been revised.
• The console accepts extra commands.
• The results form has been retouched.
• VOG files have been adapted (backward compatibility is lost for some variables).
• The result files and result model have been adapted to accept frames.
• The unsteady calculation mode has been removed.
• The velocity plane has been removed (no longer compatible with the results model).

Tucan 2.2

• Important bugfix on induced drag calculation (downwash)
• Bugfix on lifting surface twisting

Tucan 2.1

++ Import/Export STL and native
++ Interoperability with Console (remote calculation)
++ Intel MKL wrapper
++ Minor bugfixes

Tucan 2.0

This is the first version containing the new algorithm to calculate air-loads over closed surfaces.

Tucan 1.3

This version contains several corrections in the kernel and additional features.

Tucan 1.2

This version contains important changes in the calculation core.
Bug-fix: corrected the asymmetry of the potential functions that caused twisted panels to behave differently when changing the order of the nodes.
New feature: imported surfaces.
Other changes: some of the nodes of the XML res files have been renamed, old res files need manual adaptation or recalculation.

Tucan 1.1

This version contains a critical bug-fix not seen in the version 1.0.
