Menu: Geometry->Covering mesh
Another feature in GiD is the calculation of the involving mesh of a set of points or nodes. To switch the visualization of this mesh on and off just select Geometry -> Covering mesh. After saying 'Yes' to the visualization of the covering mesh, you will be asked for a number. This number is the distance between the covering mesh and the points.
This option is not only available for points, but also for every mesh/set present in GiD.
Note: This covering mesh is recalculated when the mesh is deformed. So in a particle movement system the covering mesh will also move along with the particles.
This mesh can also be saved through Files -> Export -> Cover mesh.
