I'm still not completely understanding what you want done. Since the two data sets have significant space between them do you want to fill in that space with extra cells or do you want to translate one of the data sets to get rid of the space between? If you want to add in cells then it might be easiest to merge the data sets (GroupDataSet filter and then MergeBlocks filter like below) and then use the vtkDelauney3D filter to create a new grid that keeps the point data. <br>
<br>If you want to translate one of the grids to get rid of the space between them you'll need to use something like the CleanToGrid filter to get an unstructured grid from your rectilinear grid. Then you can use the Transform filter to move it to the proper position (in this case -0.10000001489999999 in the z direction for <a href="http://test.2.nc">test.2.nc</a> since the vtkCleantoGridFilter is quite finicky). Then use GroupDataSets filter to merge the data sets into a multiblock (right click on the GroupDataSets filter to select one of the test.*.nc files and the the Transform filter). Finally, you'll need to use the vtkCleantoGrid filter again to get the proper connectivity. You'll want to check what it does with the point data at the merged points though.<br>
<br>If neither of these is what you want then you'll need to be very descriptive of what you hope to accomplish in order for me to help you any more.<br><br>Andy<br><br><div class="gmail_quote">On Thu, Jan 28, 2010 at 5:51 AM, Julien Bodart <span dir="ltr"><<a href="mailto:julien.bodart@gmail.com">julien.bodart@gmail.com</a>></span> wrote:<br>

But looking at the problem, I am afraid you will tell me that there is no solution.<br>
As you will see there is no duplicate points, thus Paraview cannot guess it.<br>
What is the best way to make them paraview-compliant? Add duplicate cells?<br>Thanks.<br><br>Julien<br><br><div class="gmail_quote">2010/1/27 Andy Bauer <span dir="ltr"><<a href="mailto:andy.bauer@kitware.com" target="_blank">andy.bauer@kitware.com</a>></span><br>
<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">To be clear, I meant first use the group data set filter or merge block filter to put all of the cells in the same data set and then use the clean to grid filter to get rid of duplicate points. Points won't get merged if they are not within a certain distance from each other. So again the real problem isn't that all of the cells aren't in the same data set but the fact that the grid connectivity is not correct. If you are doing this in parallel this can also have an affect on appearance due to not having the correct connectivity between cells on different partitions/processors.<br>
<br>If you can give me a more detailed description of the problem and send the grid I can take a closer look at it.<br><font color="#888888"><br>Andy</font><div><div></div><div><br><br><div class="gmail_quote">

Well, actually I think I tried all the filters, included the clean to grid one.<br>In my case there is actually no duplicate point between files:<br><br>for example:<br><br>file-1, z-coord: 0.0,0.1,0.2<br>file-2, z-coord: 0.3,0.4,0.5<br>
<br>And the grid is structured.<br><br>Maybe in this case there is no way to make a single dataset?<br><br><br><br><div class="gmail_quote">2010/1/27 Andy Bauer <span dir="ltr"><<a href="mailto:andy.bauer@kitware.com" target="_blank">andy.bauer@kitware.com</a>></span><br>
<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Try using the clean to grid filter. Although all of the cells are in the same data set (probably an unstructured grid), the filter does not realize that there are duplicate points and because of this the grid connectivity is probably not what you're expecting.<br>

Hi,<br><br>I am new to Paraview, thanks to the new Netcdf Reader of 3.6 release. (Thank you very much for that)<br>Therefore my problem is probably really trivial but I can't get it resolved...<br>I am reading 2 or more netcdf file describing several part of the grid.<br>
The complete domain is a cube(rectilinear grid), sliced in a given number of files. There is no ghost cells so there is no obvious match between files.<br>When I try to merge the different block (using the group dataset filter or merge block), I end up with a split domain, leading to a visual gap between each sub-domain, whether I am plotting contour , vertical plane or whatever.<br>
Is there a way to "really" merge those subdomain to end up with a single domain.<br><br>Thanks in advance!<br><font color="#888888"><br>Julien<br><br>
