Compute the second moments and product moment of area for a given 2D element about its centroid. These are:
I_xx, the second moment of area about an axis through the centroid of the element parallel to the x-axis;
I_yy, the second moment of area about an axis through the centroid of the element parallel to the y-axis;
and I_xy, product moment of area through the centroid of the element.
Formulae for these quantities may be found e.g. in the following reference:
Mechanics of Materials James M. Gere (Author), Barry J. Goodno. Cengage Learning; 8th edition (January 1, 2012)
This method is used within GetShortAxisOfElement() to compute the direction of the shortest principal axis passing through the centroid, or 'short axis', of the element.
Note that by definition, the second moments of area must be non-negative, while the product moment of area may not be.

Calculate the polygon distribution for the mesh: number of {0, 1, 2, 3, 4, 5,..., 12+}-gons. Note that the vector will always begin {0, 0, 0, ...} as there can be no 0, 1, or 2-gons, but this choice means that accessing the nth element of the vector gives you the number of n-gons which seems to be most natural. All 12-sided and higher order polygons are accumulated in the array[12] position.

c_vector< double, SPACE_DIM > ImmersedBoundaryMesh< ELEMENT_DIM, SPACE_DIM >::GetShortAxisOfElement | ( | unsigned | index | ) |
Compute the direction of the shortest principal axis passing through the centroid, or 'short axis', of a given element. This is the eigenvector associated with the eigenvalue of largest magnitude of the inertia matrix
J = ( I_xx -I_xy ) ( -I_xy I_yy )
whose entries are computed by calling the method CalculateMomentsOfElement().
Note that if the nodes owned by the element are supplied in clockwise rather than anticlockwise manner, or if this arises when any periodicity is enforced, then the sign of each moment may be incorrect change. This means that we need to consider the eigenvalue of largest magnitude rather than largest value when computing the short axis of the element.
If the element is a regular polygon then the eigenvalues of the inertia tensor are equal: in this case we return a random unit vector.
This method is only implemented in 2D at present.

Determine whether each element is on the boundary or not, and call the element's SetIsBoundaryElement() method.
It is not possible to define in precise terms whether an element is on the boundary (as there is no commonality of nodes as in a vertex population). Instead we use information from the node locations voronoi diagram. Any nodes with infinite voronoi edges are certainly in boundary elements, as well as nodes in elements whose voronoi cells are "too big".

void ImmersedBoundaryMesh< ELEMENT_DIM, SPACE_DIM >::UpdateNodeLocationsVoronoiDiagramIfOutOfDate | ( | ) |
Update mNodeLocationsVoronoiDiagram if it is out of date, which is the case when mSummaryOfNodeLocations is out-of-date, i.e. nodes have moved location. This ensures the update is performed at most once per time step.
