Here is a quick and dirty solution:<br>
<br>
// --- scalpel2.geo ---<br>
Merge "scalpel2.step";<br>
Mesh.CharacteristicLengthMax = 2;<br>
Mesh.Algorithm = 1; // MeshAdapt<br>

The picture of the mesh I got is attached.<br>

If you share that example of a scalpel with Compound

<div style="overflow:hidden"><span>Hello,<br>
In this picture the top is the
original mesh of the scalpel. In
the bottom<br>
I defined some compound surfaces.
The mesh changed but the problem
is that<br>
even in the one compound surface
the mesh goes from point to point
and is<br>
smaller in the areas where there
used to be a smaller surface. I
would like<br>
to be able to have a uniform mesh
across surfaces. Does this make
the<br>
problem clear? Thanks for your
help.<br>
