I am having some problems in the pdetool toolbox (Using Matlab 2017a): My code defines the outer geometry of my system as the domain number 1 for a certain geometry:
However, for a second geometry (similar to the previous), the code labels the outer geometry as a different number (3 in this case).
I need to have different PDE coefficients in the outer domain. Is there a way to know which domain number is the outer rectangle of my system?
