[vtkusers] Joining 2 strutured grids

[Fred Fred]

Hmmm, my problem is not here I think but rather on how to connect both grids by tetrahedra so as to have a multiblock dataset emcompassing the whole 3D area, ie the original low-resolution grid, since the reason I have to face this issue comes from the fact I have run a more accurate simulation on part of the original grid and to do it I have oversampled the grid in a specific zone.

Hi "Fred Fred",One way would be to create ImplicitDataSets for each of your structured grids and then use the ImplicitBoolean to combine the two datasets into one.

Hello,
I have 2 structured grids of different granularities, one of them being partially included in the other. When I try to render these grids, there is of course an overlapping region in which the visualization is not nice. So I can just visualize the non overlapping regions of both grids but this yields to a gap of course. My problem nom is: how to join these 2 grids, ie how to tetrahedralize the gap between them? I need some tetra Delaunay. I suppose this problem has been addressed by several vtk or PV users and may be I could get some hints here.


Thanks in advance for your help.
