comment NDSolve PDE, not enough boundary condition?
Maybe adding some background of the PDE will attract more attention?

Well, you should not place a space between "@" and my name, or I won't get the reminder.

comment About Compile Function
Considering the code you showed in your previous question, I want to remind you that Compile isn't a panacea for speed, it'll lead to more limitation in programming and may bring you endless grief indeed. Have you already read this and this post?

comment How to define two polyhedron intersect or not?
Well, if you want to call someone who isn't the original poster that appearing in the comment, you need to add @someone in your comment, or others won't see the reminder. RegionIntersection can be used for 3D object, for example d1 = {{0, 0, 0}, {1, 0, 0}, {0, 1, 0}, {0, 0, 1}}; d2={{0,0,0},{1/2,1/2,1/2},{1,0,0},{1,1,0}};r=RegionIntersection@@(Tetrahedron/@{‌​d1,d2});RegionMember[r,{x,y,z}]//Reduce
