Hi everyone, first of all I was looking for a section where to introduce me, but I did not find it, I will do it here.
I'm Gaetano and I'm a student in Palermo University.

I'm trying to make a mesh of a piece of beam with stirrup and bars, but I'm having some trouble with stirrup, it is inside the main domain, and I do not know how to solve it. I'm attaching the .geo file, hoping someone could help. Maybe there are other way to mesh it, I do not know.

Thank you

// Input
Rectangle(1) = {0, 0, 0, 300, 300, 0};
Disk(2) = {50, 50, 0, 10, 10};
Disk(3) = {50,250,0,10,10};
Disk(4) = {250,250,0,10,10};
Disk(5) = {250,50,0,10,10};
Rectangle(6) = {30,30,146,240,240,10};
Rectangle(7) = {40,40,146,220,220,10};


// Start Operations
s() = BooleanFragments{ Surface{1}; Delete; }{ Surface{2,3,4,5}; Delete;};
ext() = Extrude{0,0,300} {Surface{s()}; Layers{10}; Recombine;};
st() = BooleanFragments{ Surface{6}; Delete;}{Surface{7}; Delete;};
Recursive Delete {Surface{7}; }
Extrude{0,0,10} {Surface{22}; Layers{10}; Recombine;}
BooleanFragments{ Volume{5}; Delete;}{Volume{6}; Delete;}

// Mesh Options all elements needs to be Hexa
Mesh.RecombineAll = 2;
