During the runtime, the user is notified about completion of individual phases of the mesh generation, about the number of generated mesh entities, about the nominal profile before and after renumbering (if nodal renumbering was required), about the mesh quality (if quality report was required), and about the time (if running without graphic interface) and memory consumed by the mesh generation (only mesh entities are considered).

The number of mesh entities is provided separately for the total
number of mesh entities in the mesh (total) and for the number of the
mesh entities in the output of finite element mesh (FE).

The nominal profile is defined as number of entries in the upper
triangular part of the connectivity matrix (Laplacian matrix of the
mesh graph), which have at least one nonzero entry with the same column
index and smaller row index, increased by number of nodes. In the case
of quadratic elements, the full connectivity is considered. The
nominal profile multiplied by square of degrees of freedom per node
can be used to estimate memory requirements for characteristic matrix
of the discretized governing differential equation in the finite
element analysis.

The quality report depends on the actually used ** -q** option. It
usually provides the arithmetic and harmonic means of selected quality
quantity, the worst quality, and the distribution of the quality into
three quality intervals expressed as the number of elements falling
into each interval and corresponding percentage of the total number of
elements. If required, a more detailed quality distribution is
generated.
