open area mismatch at inter-block boundaries of all blocks
as % of total open area at these mesh boundaries = 8.55612E-11

hello everyone!I have a question about simulation.
first,I do not know what mean for "warning - surface area for component 1 is zero".I set component 1 as a porous component.second ,I have set inter-block by fixed point,why it tells me "open area mismatch ".
so I want to ask if they affact the result and how to solve them?thank you!
