Hello there,
I wrote a conversion utility to transform point data into hexahedral cell data which is then being reshaped into the form of a blockMesh dictionary. Running blockMesh on the resulting dictionary outputs the required polyMesh data set. My approach is to consider each hex cell a single-cell hex block. Thus, the blockMeshDict contains solely hex blocks, each made of exactly one cell.
Everything seems to work just fine, even application of boundary conditions (checked using ParaView). But when I run OpenFOAM (e.g. icoFoam), the converged results show only the boundary values interpolated over the cells adjacent to their related patch (see picture).

Hence, I assume the cells are not properly connected. Web and forum search didn't help me in finding a way to connect the cells.
Is there anybody who can give me a hint, where to look at or is my cell:=block approach too poorly suited?

Thank you very much in advance!

Well, I don't know what I did wrong previously, but now it works just fine
