[Paraview] Multipiece unstructured grid field data (PVTU reader)
Hello, I've saved data as multi piece unstructured grid (pvtu) format which is composed of a set of vtu files and one pvtu. When I load the pvtu using a vtkPXMLUnstructuredGridReader, I get the compound data of all the vtu files. This is true for point and cell data, but field data does not have the same behaviour. Indeed, it seems that only the last vtu file field data appears in the final data set. I see in the vtk sources that the code used for field data is a little bit different (as seen in int vtkXMLPDataReader::ReadPieceData()in file vtkXMLPDataReader.cxx:380). Field data use a simple copy for each piece, and point/cell data use specific methods that offsets the memcpy of arrays for each piece in the resulting data set... Is there a mean to get the compound field data in final data set ? How can I retrieve all my pieces field data ? Thanks in advance for your support, Yves ___ 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 Follow this link to subscribe/unsubscribe: http://www.paraview.org/mailman/listinfo/paraview
[Paraview] VRPlugin - VRPN ModelTransformMAtrix Grab problem
Hi guys, i am testing the VRPlugin (VRPN connection only at the moment due to the issues i had with the VRUI connection) with a Razer Hydra joystik. The tracking of the position is fine, but when i connect one of the two joysticks and its three buttons to the grab of the ModelTransformMAtrix, i get a weird problem with the translate. The rotation and the reset word ones work like a charm, but when i click the translate world button (in the state file below, the Hydra.L2) the scene starts bouncing and flickering almost out of control. I see that it also translates, but it rotates around with this flicker also if i'm not even touching the tracked wand. Any idea on what might be causing that?

Re: [Paraview] Surface LIC Problem
Hi Burlen, Richard, Utkarsh, Thanks for your advices. I misunderstood that the Surface LIC Plugin should calculate some kinds of the vector fields on surfaces. My models are generated by NS solvers, so the surfaces have non-zero vectors without slipping or moving wall. For example, can I calculate surface friction vectors with ParaView? I have flow fields and other physical constants. # Extracting issue was solved by using Extract Subset filter. # My meshes were structured grids of turbomachinery in this time, # so all the walls can be extracted by the ijk coordinates.

With Euler CFD results, the velocity vector is not zero at the wall, and you can use this vector. With Navier-Stokes CFD results, the velocity vector is zero at the wall, and you have to use the skin friction vector instead.

First I applied Surface LIC to the walls, the results are something wrong. Next to the fluids, they are OK. But there are extra walls which I don't want to visualize (ex. Inlets/Outlets, external boundaries). Maybe the reason of the walls are that they don't have the velocity values of main flows. I also tried the Resample with Dataset filter for linking main flows to the walls. The results are roughly good, but sometimes the resampling qualitys are poor (dropping the values). Is there a good way to visualize the part of the walls' LIC? My sources have complicated shapes, so I want to make the best use of the information of blocks of walls.

Re: [Paraview] Surface LIC Problem
Hello. What are these non-zero surface vectors without slipping or moving walls ? With NS solvers, the velocity vector in an axis system bound to a wall should ALWAYS be zero at the wall (moving wall or not moving wall): this is the adherence condition. As LIC needs a non zero vector at the wall in an axis system bound to the wall, you cannot use the velocity vector, and you MUST use the skin friction vector. My NS solver gives the three components of the skin friction vector in an axis system bound to the wall as three scalar arrays. So I have to use the PV Calculator filter in order to build the vector array from these three scalar arrays, something like Friction_vector = x_component*iHat+y_component*jHat+z_component*kHat But you may also use the Calculator filter to build the friction vector from the stress tensor and the normal vector at the wall. It depends on the output of your solver. Richard Le 14/02/2014 14:34, Magician a écrit : Hi Burlen, Richard, Utkarsh, Thanks for your advices.

[Paraview] Load state error with MPAS Ocean NetCDFReader data type
Dear Paraview Mailing list, I am a developer on the MPAS-Ocean project and we are having trouble with saved states in Paraview corresponding to loading the netcdf (*.nc) data file, loading and plotting a variable (say kineticEnergyCell), saving the state as a psvm file, and then reloading it. At a minimum, the plotted quantity is not accessible and it doesn't appear that the data structure for MPAS-O is reloaded properly. This is the simplest reproducible error. John and Boonth (cc'd) recommended I email this list with this issue. A link to the files for debugging/ testing is https://www.dropbox.com/s/b4a0b056ks3i30r/mpaso_paraview.tgz. A work-around is to simply save the variables of interest as unstructured vtku files, but this is an imperfect solution (if only because multiple vtku files in time then become required). If vtku files are utilized there is no problem with the save/load state function. My present configuration is ParaView 4.1.0 64-bit for mac via the dmg installer (ParaView-4.1.0-Darwin-64bit.dmg).
