Dead cell causes singularity?
I have a mesh where there is a cell which is totally surrounded by walls, i.e., it is a "dead" cell. This cell is isolated from others.
When I do icoFoam, it exited with a segment fault.
So what could be the problem? Does this cause singularity? Or the status of the system is undetermined?
One thing I might do is to delete these "dead" cells from the mesh since they don't contribute to anything. But how can I do that?
Greetings Xiaofeng Liu,

You can use those instructions as a reference to the steps you need to do:
Thanks for the reply, though you answer is not relevant.
I have figured out this. For the record, it seems that those dead cells has no effect on the solution at all. They are not participating in the calculation since no flux could pass through the surrounding walls.
You might be able to subSet these cells out but again it is not necessary.
Well, I can't always be right ;) But still, I did (sort-of) answer your last question on the initial post:
