[Gmsh] Fourth Parameter in "Point" geometry..?

[rakesh patil]

Hello,

I am new to GMSH and was just going through the tutorial. In the Geometry
module, I just happen to come across this point:

Point ( expression ) = { expression, expression, expression <, expression >
};

It says that first three expressions on the RHS is x, y, and z values of a
particular point. What is <. expression> used for? It is mentioned in the
documentation that

the optional last expression sets the prescribed mesh element size at that
point

Any examples over this issue, so that the element size can be controlled by
this optional parameter.?

Thanks in advance.

Regards
Rakesh Patil
