Re: [Paraview] Assemble Variables into Tensor

[Nicholas Richmond]

Hi Utkarsh,

Using the script you wrote with the Programmable Filter does the job
nicely! Thanks so much for going above and beyond to help me assemble the
arrays into a tensor. Programmable Filter never occurred to me and I am now
looking forward to exploring Chapter 13 of the Paraview Guide to see what
else I can do with it.

Many thanks,
Nick Richmond

[Paraview] Assemble Variables into Tensor

[Nicholas Richmond]

Greetings,

I have a vtk Polygonal Mesh with six separate arrays (sigma_xx, sigma_yy,
sigma_zz, sigma_xy, sigma_yz, sigma_xz). I'd like to assemble these into a
tensor so that I may apply the Tensor Glyph filter.

After reading that the paraview.simple.TensorGlyph

expects
a symmetric tensor with the order XX, YY, ZZ, XY, YZ, XZ, I tried to
assemble the six separate arrays into a single array with the Python
Calculator, but have been unsuccessful.

I've tried a variety of approaches, including:

*Expression:* np.array([sigma_xx, sigma_yy, sigma_zz, sigma_xy, sigma_yz,
sigma_xz])
*Array Association:* Point Data

I can make a vector of the normal stresses using the "make_vector" function
from paraview.vtk.numpy_interface.algorithms, but there is no "make_tensor"
function to assemble both normal and shear stresses into a single symmetric
tensor.

Any guidance would be most appreciated.
Many thanks,
Nick Richmond

Re: [Paraview] Compiling ParaView for Windows x64 Release

[Nicholas Richmond]

​Hi Yoshimi,

I copied the six DLLs from Qt into the Release directory and it worked!
Thank you very much for your help with this.

Best wishes,
Nick​

[Paraview] Compiling ParaView for Windows x64 Release

[Nicholas Richmond]

Greetings,

I've been having some trouble building ParaView 5.4.1 on my system. I'm
hoping a Windows-savvy user might be able to lend some insight. ParaView
builds just fine under "Debug" mode, but when built as "Release," I get
four errors signaling that "The procedure entry point...could not be
located in the dynamic link library" for paraview.exe,
vtkpqPython-pv5.4.dll, vtkpwWidgets-pv5.4.dll, and vtkpqCore-pv5.4.dll.

The debugger shows:

Exception thrown at 0x7FFD18054B90 (ntdll.dll) in paraview.exe:
0xC139: Entry Point Not Found.
Exception thrown at 0x7FFD18054B90 (ntdll.dll) in paraview.exe:
0xC139: Entry Point Not Found.
Exception thrown at 0x7FFD18054B90 (ntdll.dll) in paraview.exe:
0xC139: Entry Point Not Found.
Exception thrown at 0x7FFD18054B90 (ntdll.dll) in paraview.exe:
0xC139: Entry Point Not Found.
The thread 0x4fcc has exited with code -1073741511 (0xc139).
The thread 0x6c7c has exited with code -1073741511 (0xc139).
The thread 0x65a0 has exited with code -1073741511 (0xc139).
The program '[15092] paraview.exe' has exited with code -1073741511
(0xc139) 'Entry Point Not Found'.

In case it matters, the only thing I'm changing in CMake is the python
version (to 3).

Any help would be most appreciated.
Thanks,
Nick

[Paraview] Importing paraview.simple with Python 3

[Nicholas Richmond]

​Greetings,

First things first, I'm using the most recent (RC3) Win64 ParaView 5.4
binary. I'm working on a project with Python 3.6, and I'm having difficulty
importing the paraview.simple module. Attempting to import (from
paraview.simple import *) results in the following error:

*ImportError: dynamic module does not define module export function
(PyInit_vtkCommonCorePython)*

*During handling of the above exception, another exception occurred:*

*Traceback (most recent call last):*
*  File "", line 1, in *
*  File "C:\Program Files\ParaView
5.4.0-RC3-Qt5-OpenGL2-Windows-64bit\bin\Lib\site-packages\paraview\simple.py",
line 43, in *
*from paraview import servermanager*
*  File "C:\Program Files\ParaView
5.4.0-RC3-Qt5-OpenGL2-Windows-64bit\bin\Lib\site-packages\paraview\servermanager.py",
line 53, in *
*from paraview import vtk*
*  File "C:\Program Files\ParaView
5.4.0-RC3-Qt5-OpenGL2-Windows-64bit\bin\Lib\site-packages\paraview\vtk\__init__.py",
line 7, in *
*from paraview.vtk.vtkCommonCore import **
*  File "C:\Program Files\ParaView
5.4.0-RC3-Qt5-OpenGL2-Windows-64bit\bin\Lib\site-packages\paraview\vtk\vtkCommonCore.py",
line 9, in *
*from vtkCommonCorePython import **
*ImportError: dynamic module does not define module export function
(PyInit_vtkCommonCorePython)*

I saw this March 10 message from Utkarsh:

"*Python 3 is supported with 5.3 (except for ParaViewWeb components). We **have
dashboards testing it too. There still may be some leftovers, so **please
report if you catch anything that we missed.*"

Does this fall under the category of "please report if you catch anything
that we missed" or is it due to a lack of understanding on my part? I've
been able to successfully import this module when using a Python 2.7
environment, but I'm trying to stick to Python 3.6. Any insight would be
most appreciated.

Many thanks,
Nick Richmond
