**d4.08.03** sd_macr_elem_dyna data structure
===================================================

**Summary:**

The sd_macr_elem_dyna data structure contains the projection of the stiffness, mass and possibly damping matrices of a substructure on a previously defined basis.

It also contains the projection of the load if a loading is applied to the substructure.

This data structure is used for dynamic substructuring calculations. The dynamic macro element created can also be used as a supermesh in a mixed model.
