"Section must be closed for this type of feature."

I think this error means, the shape must form one closed loop by properly connecting endpoints. In your figure, if you need to divide the shape into smaller cells, you can use the partitioning cell feature to refine the mesh or create regions with different properties. Or you can draw seven parts for your figure.
