meshing in Salome

i've been playing around with the mesh and now it looks much better, but i have a question:

- how can I do so that the mesh is more accurate at some points, for example in front of the aerofoil?

AFAIK that isn't possible (unfortunately) yet, but if you have round shapes and use Netgen with a sufficiently low length on the 1D algorithm, you will get a fine mesh around the airfoil and course around the outer edges

Hi,

you should be able to refine your mesh locally if you use "submeshes":
submeshes let you define actually local meshing rules while the global meshing options apply everywhere else (=default meshing rules)
1) create a "coarse" global mesh with
1D hypothesis = average length and 1D algo = Wire discretisation
2D hypothesis = Triangle (or Netgen 2D)
=> compute the mesh
2) select your Mesh object and in the menu, run "Create Submesh"
select a region of your geometric object (you can partition your curves or "explode" your geometry object into edges). The simplest procedure is to "select from a mesh element".
- pick an edge to refine
- choose 1D algorithm = Wire descretization
- create a new 1D Avergage length hypothesis with a smaller size
validate and compute your mesh

You can have a look at the Geometry ad Meshing tutorial on the Wiki: it is outdated but the principle is still the same.
