Hi all,

I am currently investigating the possibility to reduce the output written by our DEM software. One case we often have is that a PolyData object is written every n time steps and we are not interested in any fields on this rigid mesh object only the current location of this object. The naive approach is to write the full information of this object using the vtkXMLPolyDataWriter during each output step. However, since the mesh is rigid and we have no active fields on this mesh it would be sufficient to save this full information at time 0. Then at each successive output all information we need would be the offset and rotation with respect to this initial object.

Is something like this possible with VTK?

Kind regards,
Arno
