Hello everyone!

I am interested in simulating the discharge of a pollutant in the atmosphere by a chamine and for this I decided to use OpenFOAM. I used gmsh to create the geometry. I created one block for atmosphere and another for the chimney. I performed a boolean union operation with the intention of connecting the two blocks. The problem is that when converting the mesh to OpenFOAM the block associated with chamine disappears. Anyone have any suggestions on how to connect the two blocks? Or some better idea to create the desired geometry?
