OpenFOAM sometimes uses name prefixes of the function object infront of the outputed field, like this
_ **functionObject:field** _
Paraview is then completely oblivious to these fields.
Weird things is, it only happens on Windows. Ubuntu distribution for example displays these fields without a problem.

Sorry it took that long. Here it is

The OpenFOAM version is v2312. I also noticed a few things, only the _.foam_ reader is faulty, when I used _foamToVTK_ to open a _.vtm_ file in Paraview, I could see the fields containing a colon in the name. However the _.vtm.series_ file also did not display the fields with a colon.
PS: Windows blocks zipping the files because of the colon in the name of a file, so I had to do it in the Ubuntu distro using WSL. I guess the same tactic would have to be used to unzip the files.

I confirm the field appears correctly in Linux. I’ll need to check windows when I can.
