Regions / cells
This could be our first attempt to combine the four bodies/surfaces from the previous screen:
A_in;
A_out;
B_in;
B_out;
to form volumes (regions/cells):
OUTSIDE (1 zone);
INSIDE (3 zones);
PIPE (2 zones).
OUTSIDE, zone #1¶
INSIDE, zone #1¶
INSIDE, zone #2¶
INSIDE, zone #3¶
PIPE, zone #1¶
PIPE, zone #2¶
However, the geometry isn’t what we wanted. The two pipes aren’t connected at the joint. Instead, they’re sticking out at each other.
