[Gmsh] adaptive meshing and pos fomat

[walter steffe]

Good morning

  In the gmh tutorial there is an example (t7.geo) which merges a
"bgmesh.pos" file containing the target mesh sizes.

May you please explain the format of this file ?

According to the extension it should be a "POS ASCII file format
(Legacy)" which is documented in section 9.3.3 of user manual (version
4.0.0). But the format of "bgmesh.pos" doesn't follow this
specification. Would it possible to have the specification of the
format used in "bgmesh.pos" ?

Thanks
