Poor quality of mesh after deformation (SU2-5.0.0)
5 Attachment(s)
I used SU2_DEF to evaluate CRM wing grid deformation, but the quality of my structured mesh is pretty bad. My question is whether the FFD box settings could affect the grid deformation,for example the distance of FFD box from the wall. Another question is whether the strctured mesh doesn't fit SU2_DEF?
Could anyone help with this ? thank you! Here are my FFD boxes, configuration file and slice of my wing (red color is deformed grid, the black one is original grid) |

There are some deformation settings that can be altered to get a smoother deformation, see the GRID DEFORMATION PARAMETERS section of the config_template.cfg file provided with the code. You may also want to check whether the FFD box boundary intersects the geometry at any point (which would freeze a plane of the box). |

The grid deformation method uses the spring analogy, which does mean that shapes that would be unstable in a physical structure (ie, a square vs a triangle) suffer from the same problems in the mesh deformation. One thing to try is using the stiffness parameters, ie using wall distance which will better preserve the shape of the mesh near the wall, or increasing the constant stiffness (with DEFORM_ELASTICITY_MODULUS, which defaults to 2E11) |
