If you need to change the nodal positions of an existing model, the “ModifyModel” component is useful. The “Pt” input expects the list of new points to be used as the model's new nodal positions (see Fig. 3.1.3.1). This can be used, for example, to impose imperfections based on the structure's first buckling mode.
