(Included in the latest version) This update URGENT! Control and Fixes database performance profiles that include defects in offsets impacts. Some corrupted data décallent point Finnesse max up to 3 degrees! At launch, the update control your database and proposes two correction solutions: SOLUTION 1: Proposed by default, you can apply the new database naca_heliciel3 data, which is a corrected version provided with the update. (This solution is very fast and highly recommended, a backup of the last database is created)

SOLUTION 2: You can keep your last database used, and run a correction procedure via the menu of the interactive data base: data bases Files Management / Automatically correct basis. This procedure looks for erroneous profiles and recalculates all polar erroneous profiles. This second option is useful only if you have calculated the polar for a series of profiles and created a database of personal data that you want to keep

It is now possible to display the pressure on the surfaces of the blades in the 3D model. A wide color matching / pressures can clearly see the pressure zones. This feature is particularly useful for the optimization of propellers or foils subject to the constraints of cavitation:

• 
• One option for creating polar "Low Reynolds" has been added in the interactive data base. This function increments the Reynolds 10000 to 10000 in the low Reynolds, and a parameter optimization calculation was conducted Xfoil. The computation time was reduced by polar.
• Few changes in the presentation of some polar graph were made.

• 9.0.0.21 version of September 30, 2011
  • A results message for the wings were added to the list of message, some changes in the presentation of values ​​in the force diagram and viewing the downwash at the particles in the interface of the 3D model. The profile schema that appears for each element has been modified at the visualization of the downwash.
  • The ability to modify the parameters Xfoil added in "Settings Xfoil" tab at the interactive data base.Ceci helps control the parameters of the function that is executed when panneling calculations Xfoil. The panneling is to decompose the profile panel which is just manage the distribution. The convergence of calculations Xfoil is strongly influenced by the panneling. The panneling function was also added al interface tracking profile as an additional tool for editing profiles.
  • A Reynolds 50 000 was added as a second pole at the calculation procedure of polar patterns. The list is now calculated polar 10000, 50000, 100000, 200000, 300000 ..... 1000000, 3000000, 5000000.
  • The edition of the boundary layer has been improved, the calculations are now stored in the database each time that an edition of the boundary layer is demandée.Ceci avoids to restart Xfoil at each calculation, saving time is therefore.
  • The calculation of polar for a given profile was accelerated at the registration procedure points calculated (time savings is substantial for the database with many profiles)

• 1 version 9.0.0.20 September2011
  • the update's available now display automatically in the software opening: During this operation no information is sent from your computer. Heliciel just trying to connect to internet and will read the latest available version of heliciel.com, this function is deactivated on if you do not want to update.
  • The edition of the boundary layer has been corrected to better manage cases of non convergence calculations Xfoil.
  • The parametrage radius of the blade root has been changed to allow better accuracy, this parameter is given in% of the radius at the blade tip by a cursor, the cursor increment was reduced 0.5%
  • few mods at the material editor ...

• 9.0.0.18 version of August 29, 2011

Improved editing 3D boundary layer model and data base: Xfoil settings have been modified to improve convergence so the quality of the results of calculation of the boundary layer. The visualization of the boundary layer is used to control the interaction between the blades. If the boundary layer of a blade makes contact with the following blade, it is estimated that there are between the blades disturbance

• 9.0.0.17 version of August 26, 2011

An edition of the boundary layer is now possible from the 3D model and data base.

A retro design defect has been corrected (the selection button profile law profile should not be accessible in retro fashion design, so it was soon on when the retro design mode is enabled)

• 9.0.0.15 version of August 25, 2011

A bug on the reverse engineering has been reported to me by a user (appeared in version "9.0.0.13 of 20 August 2011"), to this course was corrected urgently. Thank you for your vigilance and your constructive criticism, do not hesitate to contact me any bugs or problems to: _contact@heliciel.com_.
