Problems with Lagrangian particle visualization in ParaView

[wyldckat]

This was a question sent to us via contact form recently:

Greetings!

This is actually a problem in many versions of paraview, but I encountered in BlueCFD 2020-1 too and I have to use this version with windows...

So, when lagrangian particles used (current example: coalChemistryFoam/simplifiedSiwek), I cant visualize the particles in paraview(initialized with paraFoam command). I am sharing the error below, it is pretty self explanatory but It is impossible to change lines in all timestep data. Is there a way around for this?

Best regards,

For this, we developed the following function object: https://github.com/blueCFD/lagrangianExtraFunctionObjects

Usage instructions are provided in the README.md file and look into the respective branch for more instructions: https://github.com/blueCFD/lagrangianExtraFunctionObjects/branches

Greetings Mr. Santos!

I actually saw that link while looking for a solution, but there were no files (and there are still no files) so asked directly to you. Now I found this link, I guess it is already compiled with 2020 version, and this instructions will save me I think.

Thank you for your time,
Have a great new year,
Eren.
