Hi, I am postprocessing an OpenFOAM CFD simulation in ParaView using python script and paraview tracer. I want to obtain slices with total pressure coefficient plots (managed to get this working ok) and velocity LIC. Unfortunately I am struggling to change slice representation to Surface LIC - all the plots I am getting from this script use “Surface” representation.

Scroll to line 274 to see how exactly I am trying to switch to LIC.

If you have any ideas on how to troubleshoot this I’d really appreciate help!  
Regards!

I tried a simpler script that seems to work perfectly on paraview master.[test.py](https://discourse.paraview.org/uploads/default/original/1X/994cb70fd64749e8c06d67940253e52653f12842.py) (5.5 KB)

Hi Mathieu,

Thanks for getting back to me!

1. When I try to just run your script I get a message

_Traceback (most recent call last):  
File “test\_LIC.py”, line 36, in   
wavelet1Display.GaussianRadius = 0.1  
File “/usr/lib/paraview/site-packages/paraview/servermanager.py”, line 453, in **setattr**  
“to add this attribute.”)  
AttributeError: Attribute GaussianRadius does not exist. This class does not allow addition of new attributes to avoid mistakes due to typos. Use add\_attribute() if you really want to add this attribute._

1. I tried following your advice though and modifying my original script to use

_slice1Display.SelectInputVectors = [‘POINTS’, ‘U’]_

slice definition, however this also results in the following error:

_Traceback (most recent call last):  
File “postProZ\_v1lic.py”, line 237, in   
slice1Display.SelectInputVectors = [‘POINTS’, ‘U’]  
File “/usr/lib/paraview/site-packages/paraview/servermanager.py”, line 453, in **setattr**  
“to add this attribute.”)  
AttributeError: Attribute SelectInputVectors does not exist. This class does not allow addition of new attributes to avoid mistakes due to typos. Use add\_attribute() if you really want to add this attribute._

Any ideas how to troubleshoot this?

Thanks,

I’m sorry, I always forget that generated python script are not retro compatible.  
With which version of ParaView are you working ?

Thanks, managed to get it working now 🙂
