Hello J.,
I have found the easiest way to change the mesh resolution in gmsh is the
following:
1) open the associated ".geo" file:
a) using gmsh - Modules->Geometry->Edit file
- If gmsh cannot find the editor you may need to
configure Tools->Options->General->Advanced
b) or using a text editor
2) edit the scaling parameter in the point definition:
for example if the point is defined as "Point(1) =
{1, 1, 1, 0.1};",
- the value in parenthesis is the
"point id"
- the first 3 values in braces are the
coordinates
- the last value in braces is the mesh
resolution at the point
3) reload the geometry: Modules->Geometry->Reload
4) mesh
hope this helps.
there may also be a gui only way.

Hi, I have a very small mesh of 2cm x 1cm (2D) and I have a problem optimising
the cell sizes in Gmsh. At this point I do it by hand with trial and error and
also I saw that the triangulation algorithm affects my results. For example if
I select Frontal I get quite different results.
Could you please kindly suggest me any settings that could balance precision
and performance for such a small size?
Moreover, is there any auto optimisation tool that could help selecting the
optimum cell sizes?
Thank you very much!
Kind regards,
J.
