[Gmsh] element size

[Sebastian Theilenberg]

Hi all,

i'm having trouble finding out what exactly the size of a
three-dimensional element in gmsh is, since this size is specified via a
length.

Does the size match the shortest or longest edge? Or is some volume
computing involved?

And is there an easy way to determine the expected size of hexahedrons
after recombination? I believe the specified element sizes are used to
create the tetrahedral mesh, and after recombination the elements are
much smaller.

Thanks in advance for your help,
