Hi,

The mesh statistics is independent of which physics interface you use. Right-click the Mesh node and select Statistics. Note, however, that the number that you get reported as Mesh vertices is the number of corner nodes. Mid-edge, mid-face, and centroid nodes are not included. That is, it is the number of nodes if a linear discretization is used.

If you want to know the number of nodes actually used, it will in general be the same as the number of degrees of freedom when you use the the acpr interface, since there is one degree of freedom per node. (This is not the whole truth, since some boundary conditions, for example, could add extra degrees of freedom).

Regards,
Henrik
