[Technical] how to change geometry and related mesh automatically

immortality · April 13, 2013, 10:27

I want to work on a naca0012 airfoil with a flap and want to find an aerodynamical design for more cl/cd.this optimization should be done according to an algorithm like ant colony.how can i change geometry and mesh automatically during run with OpenFOAM?
is there an open source software like dakota for changing in mesh?

Hi Ehsan,

It sounds like you want to do shape optimisation? Maybe you could benefit from a look on the adjointShapeOptimisation solver in OpenFoam (I have never tried it, though).

With respect to mesh motion, then OpenFoam comes with a large suite of mesh-deformation utilities, and in OpenFoam-1.6-ext some code also allows for complex topological changes of the computational domain through a linking to the mesquite software package.

Kind regards,

Niels

Greetings to all!

BladeDesigner comes to mind... there was a brief talk about it here on the forum: http://www.cfd-online.com/Forums/ope...-aerofoil.html

Best regards,
