Hi everyone,
here is the description of the problem.
I have a rectangle with some circular holes in it, the inner part of the domain (denoted with D) is defined by the difference between the rectangle and the disks and the outer part is the union of the disks.
The boundary of the domain is the union of the edges of the rectangle and the circumferences.
I would like to define a boundary-distance function phi(x) that is non-negative if x is in D and negative otherwise.
I have already used the general extrusion operator to define a distance function on D and a negative distance function on the complement of D. Is there a way to "paste" the two functions?
Hi René, thank you for your reply!
I'll try to apply your suggestion.
I have already tried to use the built-in operator "isdefined" that works like a characteristic function. I have defined my "pasted" function like this:
isdefinde(f1)*f1+isdefined(f2)*f2
I wonder if this my way is different from your way...
Hi Filippo. There are probably different ways to reach the same results; it often takes some tinkering ;-)
