Grading in gmsh
 

Hi all,

I am trying to grade cells approaching a line (the bottom of my domain) and am wondering if there is a way to do this similar to blockMesh's simpleGrading tool. See the image below for what I have (left) and what I would like to have (right).

I know you can specify the grid size on individual points in gmsh but can't find anything in the documentation about specifying it over a line.

This is only possible for structured mesh (transfinite line). You can give a geometric ratio either for one end (Using Progression) or for both ends (Using Bump).

See more in the documentation: Structured grids

Thanks Mikko, I had missed that in the documentation.
