[Gmsh] About the correct definition of the background field to combine size fields

Hi everyone,

I have a model that consists of several non-geometrical volumes 
(complex, not cubes or shperes..). There are some volumes for which I 
would like to set the target element size. For that purpose, I used the 
MathEval size field by specifying a constant expression (equal to the 
element size that I want) for the regions of interest.
The problem is the definition of a correct Background Field. Indeed, if 
I use Min, Max or MinAniso, I don't get good results since the element 
size will be the same for all the mesh..
Is there a way to combine the size fields to solve my problem ?

Thanks for your help,

Best regards,
