Create macro elements for « static substructuring » calculations or for « structural modification » calculations.

In the case of « static substructuration » calculations, the macroelement is calculated by assembling ordinary finite elements and condensing the matrices to « external » degrees of freedom.

In the case of « structural modification », the macroelement is calculated by expansion and condensation of the modal model identified (measured) at « external » degrees of freedom.

Produces a macr_elem_stat data structure.
