[Paraview] Multi-block Inspector - unexpected result
Greetings, When using the Multi-block Inspector I see behavior that I don't expect. After setting colors and opacity for individual blocks, if the model is then colored by a nodal scalar variable the solid colors persist. This isn't what happens if I add an extract block filter for each block. It gives weird effects if opacity is less than 1 in a block, where other blocks (not transparent) viewed through the transparent block are rendered by the scalar variable, but if viewed directly are rendered in the prescribed solid color. Is this a expected? I'm using the latest stable 4.2 on Windows 7 x64, with an EnSight Gold format reader.

Re: [Paraview] Colour bar and scale missaligned
Thanks Burlen,
I'll try the nightly build (if that's what 'git pull' is?). Your scalar bar
does indeed look just right; would you be willing to share the script code?
I've noticed another ugly quirk with the new default scalar bar, the number
format applies to all values except the limits, so there seems to be no way of
suppressing a limit value from being displayed as 0.11 (for
example).
Regards,
Bob

Subject: Re: [Paraview] Colour bar and scale missaligned
I just tried to replicate on a recent
git pull and I was not able to. It may be fixed. but I'd like to
confirm that the scalar bar widget has been a bit flaky lately.
One thing I'd like to point out about your screen shot is the use
of too many different font sizes in the lables. Your examples only
has 2 sizes, but I've seen examples with 3. This makes the color
bar unusable for me. I end up generating my own in a post
processing step for this reason.
it would be really nice to have a simple nice looking scalar bar
for plots. A single font size is a key feature. Also I like to see
all of the labels on one side, and evenly spaced. The logic for
deciding on which side of the widget seems to be easily confused
and I've seen some crazy looking results.
Simple is better. Here is an example(made by my post processing
script) of how this looks

Hello,
I'm using 4.0.1 64 bit on Windows 7. When I limit the number of
discrete contours there is a misalignment of the scale and the
colours in the colour bar. I've attached a plot and a state file
that demonstrate the issue; a simple plane coloured by
x-coordinate with the colour bar aligned above the plane to show
the missalignment.
Is this an issue with my specific set up (graphics drivers ...)
or do others see it too?
Thanks for your time,

Re: [Paraview] Colour bar and scale missaligned
Hello Burlen, That was very kind of you to share your scripts. I fear you may be casting pearls before a swine, but I will attempt to run them on my PC. The plots are very impressive; van Gogh meets Munch at Sheldon Cooper's flat. I'll send you a picture if I have some success.

[Paraview] Getting Python commands from the trace module (or other)
Hello, I'm using the lastest nightly build of ParaView 4.0.1 Windows 64bit on Windows 7. I'm try to develop a Python macro that will allow me to setup the scalar bar after applying some other filters to the pipeline. I'm trying to establish the required Python commands by turning on the trace feature, changing things in the GUI (specifically: Color Scale Editor - Interpret values as Categories - Color Legend Tab, change font size, tick flip labels, tick show NaN, label as "texty foos"), and then stop trace. I'm starting and stoping the trace directly in the Python Shell using: from paraview import smtrace smtrace.start_trace(CaptureAllProperties=True) # Do stuff in GUI smtrace.stop_trace() smtrace.print_trace() However the results is always: try: paraview.simple except: from paraview.simple import * paraview.simple._DisableFirstRenderCameraReset() Render() But none of the commands for fonts, text, NaN etc are there. I've tried many variants of dir() and help() for various combinations of objects, but have had no success and have spent far too long on something that should be trivial. Any help greatly appreciated.

Re: [Paraview] Scalar bar ranges jump around
Hello Ken, Maybe you are seeing something different to what I see when playing the different time steps. I see the relative size of each of the discrete colours in the scalar bar, changing in a random way. The ticks don't move and the numbers change appropriately, but the length of each colour is not constant. I've attached an image that shows the scalar bar from three time step of the data set in the state file I posted yesterday. One (t=96) has a good scalar bar and the other two are wrong. Just to clarify, I'm using ParaView 5.0 RC3 64bit on a Windows 7 machine. Thanks for your help, Bob On 29 December 2015 at 17:49, Moreland, Kenneth wrote: > Bob, > > I am confused.

[Paraview] Custom filter - coloring multi-block dataset
Hi, Is it possible to edit the *.cpd xml file (or other technique) of a custom filter so that the resulting multi-block geometry has a specific color (and opacity) applied to each block, and the "Coloring" in the "Display (GeometryRepresentation) is set to "Solid Color" rather than "vtkBlockColors"? The output from my custom filter has quite a few blocks that would each require the color/opacity to be set manually using the multi-block viewer. I thought of calling the custom filter from a Python macro, but when tracing the action of changing the colors and opacity via the multi-block viewer, nothing is recorded in the trace.

Re: [Paraview] Ansys to ParaView
Hi Anxo, If you're using Ansys MAPDL aka "Classic", then you have a lot of flexibility to code something in apdl to output mesh and results in a format that suits you (and ParaView). For efficient code you would need to make use of the vectorised functions like *vget, *vfun, *voper etc. If you're only going to want to do this once and therefore can't invest the time, upload your database and solution file and send me a link (or send me your apdl input files) and I'll try to upload something you can open in ParaView, less than 1 million nodes is fine. If you're using Workbench, then I believe it writes the apdl commands to define the mesh, loads and BCs, to the project directory along with the solution file *.rst (extension depends on the physics).

Hi Anxo, By upload, I mean to your dropbox account, not the ParaView server:) Regards, Bob ___ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the ParaView Wiki at: http://paraview.org/Wiki/ParaView Search the list archives at: http://markmail.org/search/?q=ParaView Follow this link to subscribe/unsubscribe: http://public.kitware.com/mailman/listinfo/paraview
Re: [Paraview] Ansys to ParaView
Hi Anxo, I don't what the capabilities of the Paraview Ansys reader are, but I don't think it can read results data, but that may have changed since I last looked. Try writing the cdb file as "unblocked" and then renaming the extension as *.inp. This may get the mesh in to Paraview but not the results. If your model isn't confidential or too large, you can upload the *.rst file to your Dropbox account and I'll try and convert it for you (*.rst files zip well). I can't give you the apdl scripts to do this as they belong to the company I work for.
