Paraview is as important as the meshing and solvers. It is the prime way to access results. More than half of the queries/problems posted on these boards and others regarding openfoam are related to paraview and parafoam and the special readers.

Couldn't a knowledgeable person go over the paraview related queries, the installation scripts (which fail in many cases) and the documentation concerned with paraview access using parafoam and the special reader. Many people don't have the perseverance I do in getting this running and likely give up and move onto other software.

I think these issues need to be resolved and are essential for the increase in the size of the openfoam community.

I am new to openfoam. I just installed openfoam2206 on Ubuntu 22.04 LTS using WSL on windows 10. But wen I check the
PHP Code:
I get the following report.

Software Components
Software Version Location
flex *** not installed ***

make *** not installed ***

wmake *** not installed ***

gcc *** not installed ***

g++ *** not installed ***

icoFoam *** not installed ***

Base configuration ok.
The foam installation contains 2 critical error(s).

Could anybody help me or someone had the same issue already?

Hello everyone,

I installed openfoam2106 on ubuntu 22.04 and everything goes well (see installation output attached).
When I run cavity test case everything goes well.

But since I want to work with multiphase, I run the tutorial DTCHull and the simulation crashed (the time continuitu error exlplded and the forces also...).

But if I installed openfoam2212 everything works fine....

I'm confused... Can someone help me explaned what is happening?

Kind regards,
