Test case for rans optimization?
Hello developers.
Are there any test cases for rans optimization? thanks |
Hi,
There are a number of shape design examples that can be found in the TestCases directory. Please see TestCase/optimization_rans/ for a set of several examples. You should find rans-based design cases for both an airfoil and a wing there. Hope this helps, Tom |

and another question, i want to carry out some optimization for super/hypersonic flows. can SU2 realize it? or can u give me some suggestion.? Thank u |

Now i have other questions. i tried to realize rans optimization with my own grid! but some times the optimization converged only in the first step! some times the optimization collapsed after 2 steps due to the large grid deformation, and there are negative volumes or bad quality grids.. how to solve this problem?? i know that SU2_CFD support Hexahedral elements, could i use Hexahedral elements in optimization...does FEA mesh deformation support this kind of elements? because i have seen the test case of rans M6 used Tetrahedral boundary layers, bui i don,t know how to creat this kind of mesh with pointwise. |

Using pointwise to generate Tetrahedral elements as boundary layer is quite basic and easy, you could use the T-rex functionality of Pointwise V17. Here is a link of video on youtube, I think it is a good toturial for you to learn Pointwise as a beginner. http://www.youtube.com/watch?v=uz661XzE1QE How T-Rex Unstructured Meshing Aids Transonic Aircraft Drag Reduction Tommy |
