I am doing an analysis of a building in ansys cfx and recently I moved from the ansys mesher to ICEM.
Despite following tutorials and looking up on lectures and posts in this forum, I am having a problem I could not yet solve. The mesher is generating elements outside of the fluid domain.
The geometry was made in SpaceClaim, the domain included. Once inside ICEM, I used "build topology" and tried diferent things: 1) fluid and solid bodys, but in this case it created mesh inside the solid also; 2) created only fluid body, but it is creating mesh outside fluid domain; 3) with no body, the mesher create some CREATED_MATERIALS but still with elements outside of fluid domain.
All cases I used Octree Mesh Method.

siw will become famous soon enough
Odd, as you said you ran Build Topology first to generate the curves and points, did you alter the options here, see the User Guide.
