Lagrangian Coordinates

</dt>
1. A system of coordinates by which fluid parcels are identified for all time by assigning them coordinates which do not vary with time. Examples of such coordinates are: (a) the values of any properties of the fluid conserved in the motion; or (b) more generally, the positions in space of the parcels at some arbitrarily selected moment. Subsequent positions in space of the parcels at some arbitrarily selected moment. Subsequent positions in space of the parcels are then the dependent variables, functions of time and of the Lagrangian coordinates. Also called material coordinates. Compare Eulerian coordinates. See Lagrangian equations. </dd>
2. Same as generalized coordinates. [[/a>|/a> ]]
