tfisherira is on a distinguished road
I've successfully converted a .unv to foam with the command ideasUnvToFoam. This is the output:



Code:
Of 11686 so-called boundary faces 8380 belong to two cells and are therefore internal
Sorting boundary faces according to group (patch)
0: firebrick is cellZone
1: fluid is cellZone
2: heater is cellZone
3: fluid_inlet is patch
4: firebrick_external is patch
5: firebrick_inlet is patch
6: firebrick_outlet is patch
7: firebrick_to_fluid is faceZone
8: heater_external is patch
9: heater_to_firebrick is faceZone
10: heater_to_fluid is faceZone
11: heater_outlet is patch
12: heater_inlet is patch
13: firebrick_to_heater is faceZone

Constructing mesh with non-default patches of size:
    fluid_inlet    90
    firebrick_external    2151
    firebrick_inlet    206
    firebrick_outlet    152
    heater_external    625
    heater_outlet    31
    heater_inlet    51

Adding cell and face zones
 Cell Zone fluid     67488
 Cell Zone firebrick     74315
 Cell Zone heater     1639
 Face Zone heater_to_firebrick     240
 Face Zone firebrick_to_heater     52
 Face Zone heater_to_fluid     189
 Face Zone firebrick_to_fluid     7899

End
I try to split the regions using splitMeshRegion -cellZones -useFaceZones -overwrite

The intent is to be able to see all of the separated regions in paraview. Unfortunately, I am only able to see the volume regions (cell zones) for each part of the mesh and none of the boundary regions (patches) using the Extract Block filter. I can see all the regions fine with vtkBlockColors.

Hello Terence,

How do you load your case in ParaView ? with paraFoam or with the ParaView native OpenFoam reader ?

In ParaView, do you see patches in the Mesh Regions zone?
