* @brief Solid mechanics model using the embedded model.
*
* This SolidMechanicsModel subclass implements the embedded model,
* a method used to represent 1D elements in a finite elements model
* (eg. reinforcements in concrete).
*
* In addition to the SolidMechanicsModel properties, this model has
* a mesh of the 1D elements embedded in the model, and an instance of the
* MeshGeomContainer class for the computation of the intersections of the
* 1D elements with the background (bulk) mesh.
