Hi,<div><br></div><div>I am starting to use paraView to visualize geophysical property models, with good success. </div><div><br></div><div>However, I have been running in to some issues/questions will </div><div>1. What is the NaN value in codes? I have region (the air) in a rectilinear grid that I would like to exclude from the rendering. I would prefer not having to use the threshold filter, since it changes the model into a unstructured grid.</div>
<div><br></div><div>2. Using occtree meshes in paraview. I have been able to import octree mesh made in an independant program in to paraView as a legacy unstructured grid of the octree cells. I was that there is a .vso file format for octree, but I haven't able to find any further information about the file format. Can anybody recommend some sources? As well, is it possible to generate octree grids in paraView, that I could export and use elsewhere?</div>
<div><br></div><div>3. Have been running into issues with extract subset filter. When I save the state and load the state up, a get a strange behaviour for the boundary values. All of the Voi's become -1 and can't adjust them. The pipelines that follow still work, but if I re-apply the extract subset filter, everything breaks. What could be the cause for this?</div>
<div><br></div>

Are there any know issues that could cause this?</div>
<div><br></div><div>Thanks very much in advance for the help.</div><div><br></div><div>Gudni Karl Rosenkjaer</div><div>PhD student </div><div>UBC Vancouver, Canada</div><div><br></div>
