Re: [Paraview] Fetching data from xdmf temporal collection

In practice you shouldn't feel a difference, since all the heavy data handling is anyways done by VTK. Anyway, I attached a script that shows you how to read XDMF data, step through the time steps, wrap the data for numpy and print out some basic infos. Regarding the GetOutput() method, to get data object from the XDMF reader you have to use the GetOutputDataObject(0) method. But I don't know the difference between the two of them, and this also may depends on your VTK version, I'm using 6.2. -Armin On 03/23/2015 03:15 PM, Jean-Michel wrote: > Armin, > > you said you would rather use vtk directly to access raw data in xdmf > files.

[Paraview] Import h5py in python shell
Dear all, I am currently trying to use the h5py module in the Python Shell in ParaView 4.3.1 (64 bits). On my system, h5py comes from my installation of python-xy and works fine outside of ParaView. I tried to import the module by providing the path to the package, using mainly two methods: - append the path to the package with sys.path.append before doing the import - import the module using the imp package and providing the full path to imp.load_source However, both methods failed to load h5py, returing the following error : "ImportError: DLL load failed: %1 is not a valid win32 application".

Re: [Paraview] Fetching data from xdmf temporal collection
Hi Tim, Thank you very much for the input. However, the animation works fine for me from the xdmf time series. From what I understand, your script handles several separate files to generate an animation. My problem is rather to retrieve the point data values at each time step from a unique xmf file for further manipulation in python. Anyway, thank you again for your suggestion.

So we instead just got in the habit of looking at individual snap shots and if we wanted to do an animation, we would use the Python trace feature to set up our view and then make some small modifications to the generated trace script. We would wrap all of the contents in a function that took in a file name/number and output an image at the end and then we would write a small driver program that would call that function, looping over our temporal series that way. It has the added benefit of running the visualization on a cluster where each process is serial and handles a range of data files. Hopefully somebody who has gotten temporal series to work can help you out. If not, I'll be happy to share some example scripts for processing time series data as snapshots using pvpython.

Note that the font size is more of a recommendation - ParaView will pick a font size for the label based on size constraints and the number of digits in the label format.

Re: [Paraview] Custom filter: exposed properties of a Calculator filter
Cory, Thank you for your answer, you understood my problem perfectly. I noticed the problem is somewhat similar when trying to incorporate a Python calculator to a custom filter and exposing the property name (in this case, the name remains 'Expression' no matter what you specify when creating the filter). The reason I asked this question is that I need to design a filter that asks some input from the user before performing some calculations. The way I used to do this was by creating a calculator with the name of the quantity the user has to give. However, I'm afraid I'm not sufficiently skilled in C++ to delve into custom widgets. I'll try to find a workaround. Thanks again, Jean-Michel De : Cory Quammen [mailto:cory.quam...@kitware.com] Envoyé : mercredi 23 septembre 2015 15:11 À : Jean-Michel Lucas Cc : ParaView Objet : Re: [Paraview] Custom filter: exposed properties of a Calculator filter Jean-Michel, Thank you for clarifying, I think I understand now. So you see the calculator buttons and text field for entering the expression? And you want the name of the property to appear in the label? For this property, a custom widget is used in the Properties panel that does not display the property name. Hence, the property name does not show up. I see that in 3.14 the Function is displayed with a simple text field - you don't get the calculator buttons. We'd have to change the custom widget to display the property name. This would be a relatively simple change that I could walk you through if you'd like to contribute to the ParaView source code. Let me know if you are interested.

I did remember to click the + sign, and in fact the property shows fine when playing the filter later on. Only the property name, which you can choose when designing the filter, doesn't appear in ParaView 4.3. If I open the same custom filter in ParaView 3.12, the name does show up.

Did you remember to click the + sign when adding the property? The first time I tried I forgot to do that, and the Function property was not exposed in my custom filter. When I did add the property, it was exposed. HTH, Cory On Tue, Sep 22, 2015 at 5:07 AM, Jean-Michel Lucas wrote: Hi, I am trying to create a Custom Filter in ParaView 4.3.1. I am having trouble with the exposed properties of a Calculator filter: when defining the properties for my custom filter, I am selecting the "Function" property and setting the property name for this Calculator. However, when using the custom filter, this property name does not appear in the Properties panel of the Object Inspector. Is this a known bug or is there something I'm missing ? Also, is it possible to hide the calculator buttons and only leave the blank field ? This was the default behavior in (at least) ParaView 3.12.0. Thank you for your help.

[Paraview] Customize programmable filters: copy arrays
Dear all, I have been using this method (http://www.kitware.com/blog/home/post/534) to create programmable filters as XML plugins, and things work fine. With this method, is there a way I can copy the arrays in the input data to the output ? Programmable filters have a box 'Copy Arrays' that you can check: I am looking to access this property in my script so the python_filter_generator can translate it.

Re: [Paraview] Customize programmable filters: copy arrays
Thank you for your answers, both methods work fine. I am also adding new variables to the output, so if I understood Dennis' answer correctly, I should be using DeepCopy() ? However, using PassData(), it seems to me the new variable is only added to the output. Jean-Michel From: Dennis Conklin To: Berk Geveci Cc: "Paraview \(paraview@paraview.org\)" Subject: Re: [Paraview] [EXT] Re: Customize programmable filters: copy arrays Message-ID: Content-Type: text/plain; charset="utf-8" Berk, I generally want to add some new variables to the output ? if I don?t DeepCopy, then these new variables get added to the input which violates the vtk rule that a filter can?t change the input. This is the main reason that I advocate adding the capability for PointData and CellData to be partially DeepCopy (new variables added in Filter) and partially ShallowCopy (input variables just along for the ride). I suspect most filters are going to generate new variables, so DeepCopy seems to be appropriate. Please correct me if I misunderstand this.

Use ShallowCopy() instead. You don't need CopyStructure() by the way. Alternatively, you can use PassData().

[Paraview] Optimize Programmable Filter execution
Dear all, I currently have a Programmable Filter that takes a long time to execute and I am looking for a way to optimize it. The code loops over a large number of points and I have a lot of operations involving numpy arrays. What are the possible steps that I could follow to make the execution faster ?

[Paraview] Parallel visualizations of Xdmf datasets
Hi everyone, I am trying to use ParaView for parallel visualizations. I have successfully compiled ParaView 4.3.1 and tested it by creating a sphere on several processors and visualizing the Process Ids. When reading an Xdmf file however, it seems that only one processor is loading the data: am I correct in assuming that this is the normal behavior for unstructured datasets ? I used the D3 filter to do some load-balancing after reading the data, but I don't know if this is necessary for subsequent filters to work in parallel ? Also, it seems from the memory inspector that ParaView duplicates the memory footprint of the data on each processor, which quickly becomes a problem for large datasets. Is this the expected behavior, or does it depend on the reader/data format ? Any information on this matter would be greatly appreciated.

Re: [Paraview] Python script for aero-optic analysis of CFD
Dear Ben, Your data reside on the server side of ParaView, so you can't access it through ParaView proxies (like plotOverLine). Proxies only let you access some info about the data, like min and max. You have two options to access the whole array : - fetch the data from the server to the client using servermanager.Fetch (this may be computationally costly depending on the size of the data) ; - or access the data on the server side using a programmable filter.
