Finer mesh input set file

ucmsuri · March 21, 2018, 06:49

Hello,
I am very new to CFD/SU2. I am looking for a finer mesh input file for onera M6 turbulence simulation model. I can see that the current SU2 file has 43,008 hexahedral elements and 46,417 nodes.

I am looking forward to generate a SU2 file around 50 million nodes. Though there are methods on how to generate it using external tool am not able to get them working as they are propreitary. (

Similar to the square.py, is anyone having a source file for onera M6 simulation? Else, kindly suggest the simplest way of generating this with opensource.

Hello, Inorder to get finer and denser mesh for Onera M6 wing, I am trying the following procedure and am stuck in my last step when converting CGNS to SU2 with mis-match in the markers.

Procedure:
1. Downoaded the grid generator from NASA's TRM website (https://turbmodels.larc.nasa.gov/one...ics_grids.html)
2. Generated a wing prism model in *.ugird format.
3. Used the aflr3_to_cgns using the cgnstools (https://gitlabext.iag.uni-stuttgart....ools/utilities)
4. Changed the input mesh format to CGNS in turb_ONERAM6.cfg and tried generating *.SU2 output file but this is failing due to mis-match in markers.

Please find the error in the attached pic.
