Dennis,

What version of ParaView did this? I just tried 5.2, and could not get
"new" datasets to be loaded in the manner you described. Could you provide
more details?

Thanks,

Re: [Paraview] unknown properties returned by ListProperties?

[Cory Quammen]

Roman,

Looking at your original problem with the error:


   File 
"/opt/paraview-5.3.0_GL1/lib/paraview-5.3/site-packages/paraview/servermanager.py",
line 375, in SetPropertyWithName
 prop.SetData(arg)
   File 
"/opt/paraview-5.3.0_GL1/lib/paraview-5.3/site-packages/paraview/servermanager.py",
line 1296, in SetData
 self.SMProperty.AddProxy(value_proxy)
TypeError: AddProxy argument 1: method requires a VTK object


You are hitting this when attempting to set the DataAxesGrid, which is a
ProxyProperty. In your dictionary, this entry has value 'None', but it
looks like setting a property to value 'None' is not handled correctly in
servermanager.py. As a workaround, I suggest filtering out properties from
your dictionary that have 'None' as a value, i.e., do not add those
property values to your dictionary.

HTH,
Cory

Re: [Paraview] [EXTERNAL] [ParaView] find the surface area

[Cory Quammen]

Mathi,

Look in the upper right corner where it says "RenderView1", then click the
toolbutton with the square the has a vertical line running down the center
("Split Horizontal" tooltip). Click the button at the bottom that says
"SpreadSheet View". In the SpreadSheet view, change the "Showing" pop-up
menu to "CellSize1", and change "Attribute" to "Field Data". An array named
"Area" will be shown which has one entry, the area of the surface.

[Paraview] Conversion error

[Nitisha Ahuja]

Hello all,
I am facing an issue in which, I am trying to convert post.out files from
Converge into paraview files. For few files I get the following error
:

I am not sure whether this is the right place to ask this question, as the
problem can be in my software too.

But if anyone knows what could be the reason behind failure in conversion
of these file, please let me know.

P.S.. I see this error on some random files.

Best regards

By far, the easiest way to go is to use ParaView 5.5.0, out within the next 
month.  There is a shiny new filter called Cell Size, that will give you 
volumes, surface area, etc of your dataset.  It is available in Paraview 
5.5.0-RC3, from the paraview.org website.  Please let us know if you find any 
issues.

Re: [Paraview] [EXTERNAL] Re: ParaView 5.5.0-RC2 tagged, binaries available

[Scott, W Alan]

Hmmm...  No, another configuration file isn't necessary.

Could you give us the dataset (if it is small) and a File/ Save State file?  I 
tried replicating this with Wavelet, and everything looks fine...  Ditto a 
slice of disk_out_ref.  I'm wondering if it has to do with the dataset type or 
the extents (bounds, on the information tab).

[Paraview] vtkTable display

[Manochehr Bahavar]

Hello,

I am creating a Python programmable filter and I need to provide user some 
additional information. I have been using RenameSource to pass the needed 
information to user using pipeline object names. The rather long pipeline 
object names have not been causing an issue. However, I just tried to display a 
vtkTable and realized that because of the long names, the drop-down in the 
table panel takes too much horizontal space and causes the table panel to be 
too wide! Is there a better way of displaying the information or is there any 
way I can force the table panel to open under my display table and not next to 
it.

I will appreciate any help

Best,

Re: [Paraview] structured to unstructured when using multiblocks filter

[Andy Bauer]

Hi Ufuk,

It looks like you're already using multi-channel input as you're adding
since you have " g_coprocessorData->AddInput(strarr[i]); " unless that's
always just called once. We're just trying to clarify the "inputs" by
naming them channels -- I'm not sure it makes it easier to understand but
it makes it easier to talk about with others that understand that concept
in Catalyst.

Setting whole extent would look like the following at line 129 in
adaptor.cpp:
if (vtkDataSet* grid = vtkDataSet::SafeDownCast(g_coprocessorData->
GetInputDescriptionByName(name)->GetGrid())) {
ParaViewCoProcessing::ClearFieldDataFromGrid(grid);
g_coprocessorData->GetInputDescriptionByName(name)-> SetWholeExtent(ilow,
ihigh, jlow, jhigh, klow, khigh);
} else {

Here, *low and *high are global values. For example, for a 1D case if each
process has 5 points and you have 3 mpi processes
ilow=jlow=jhigh=klow=khigh=0 and ihigh=12. The
vtkStructuredGrid::SetExtent() would look like:
proc 0: 0, 4, 0, 0, 0, 0
proc 1: 4, 8, 0, 0, 0, 0
proc 2: 8, 12, 0, 0, 0, 0

This looks like you're doing it properly in grid.cpp though but I didn't
set the SetWholeExtent() in adaptor.cpp and I'm guessing that's what's
missing.

The multi-channel input should work in 5.4.1 but I found a bug that's been
fixed in the upcoming 5.5 that was affecting Live. See
https://gitlab.kitware.com/paraview/paraview/merge_requests/2212 for
details on that. It's fairly small so you can probably backport that to
your 5.4.1 build if you're more comfortable using 5.4.1.

Cheers,
Andy

Re: [Paraview] structured to unstructured when using multiblocks filter

[Andy Bauer]

Hi Ufuk,

Currently a multipiece data set always has to be nested under a multiblock
dataset. This definitely seems like an unreasonable limitation on a
structured grid under a multipiece dataset but I suspect we just haven't
had the resources to put into making this work properly. My suggestion
would be to try just having your Catalyst adaptor provide a structured grid
directly, assuming you only have one grid per mpi process, and then try
volume rendering like that. If you do this though, make sure to set the
whole extent with vtkCPInputDataDescription::SetWholeExtent().

A thought here -- instead of changing your adaptor to generate the
structured grid directly instead of a multipiece dataset, maybe create a
second "channel" through a second vtkCPInputDataDescription that provides
just a structured grid. This way you can provide both dataset types as
needed instead of having to modify code back and forth, recompile, etc. to
get different functionality. See the
Examples/Catalyst/CxxMultiChannelInputExample in the 5.5 source code for
some more details on this.

I can't remember if you were using the editions or just the full ParaView
Catalyst build but in 5.5 there will be a volume rendering Catalyst
addition.

Note that the multiblock/multipiece hierarchy will be undergoing a
significant change in the near future.

Best,
Andy

Re: [Paraview] [EXTERNAL] Help regarding visualization of velocity vector

[Andrew]

Hello.
I always use glyphs for this and they work great. It may be neccesary to
check the "Orient" option. Along with this, you usually only need to adjust
vector size and add Surface Vectors filter before Glyphs to get the surface
projection (if needed).
If you don't see the option for selecting velocity then there is something
wrong with dataset or ParaView. The "Vector" option is always there, and,
if you only have one vector variable, it is not clickable but it's there.

Re: [Paraview] Idea: move from mailing lists to discourse

[Andrew]

I think that the forum is the great idea (it has been already was proposed
earlier on this list). IMHO, forum mode is more friendly and useble for
most users.
