<div>My gmsh reader relies on the fact that each physical number is unique across dimensions. Are you saying this is no longer happening?</div>
<div> </div>
<div>This is going to be a few hours effort to change my algorithm, so please help me understand all of the ramifications correctly.</div>
<div> </div>
<div>I then need to check the dimensionality of each element I am reading in and assign it to a different group according to number and dimension? Why can't we just use names instead of numbers, and ensure that the names are unique across all dimensionalities?</div>

The motivation,according to doc/VERSIONS.txt is `bumped mesh version<br>format to 2.1<br>(small change in the $PhysicalNames section, where the group dimension<br>is now required)'.<br><br></blockquote><br></div>Exactly: it's a very small change, only affecting the optional $PhysicalNames/$EndPhysicalNames section.<br>
<br>The problem was that with version 2, we did not save a dimension (0D, 1D, 2D or 3D) together with the name. Hence we could not guarantee a one-to-one mapping between physical names and physical numbers. Indeed, physical numbers need only to be unique per dimension (you can have Physical Point(1) and Physical Line(1)).
