Could you please put the images inline into your post since we (ansys employees) can not download them.
In any case you would need to split the geometry up where you have different shell sections.
Below is a simple example where the centre has a different section to the surrounding shell. We have two parts thus that share topology (so they are fully connected at their interface) and then we assign the different sections as shown to each of them .
Thank you
Erik
