meshL sequence does not exist


I wanted to solve1D FE problem, for this purpose I have tested the very simple program :

meshL Th=segment(10) ;

An error message appears : “The Identifier segment does not exist”. I am working with FreeFEM v4.12 (the last version I suppose). What is wrong?

You have to use

 load "msh3" 

before in the script.

Thanks, the confusing point is msh3 lets think to 3D mesh.
