Hi there,

I'm having trouble figuring out how to get topoSet to do what I want...

Basically, I want to create a compound mesh where each region has different material properties. Making single simple shapes such as rectangles, cylinders and an annulus is straightforward enough, but making more complicated shapes such as the quarter-cirle annulus I've (poorly) illustrated below are eluding me.

In particular, it seems to me that it should be possible to make something like the below image by using some boolean operations--create an annulus and remove some of it by removing the portion that intersects a box. I don't know if this is actually possible via topoSetDict though.

So, any suggestions? If boolean operations are not possible via topoSetDict, how else might I be able to accomplish something like this?

Thanks in advance for any help.
