Hace los cambios oportunos cuando se ha producido un cambio en el domain.

NOTE WE CAN't DO TOGETHER BECAUSE DOF_GROUPS USING SINGLE VECTOR ****** for (int i=0; i < id.Size(); i++) { int loc = id(i); if (loc >= 0) { (*U)(loc) = disp(i); (U.getDot())(loc) = vel(i); (U.getDotDot())(loc) = accel(i); } }
