There is a class of face topologies for which Inflation can be performed, but where the results might not be what you expect. An example is shown in the picture below.
If you try to perform Inflation with such a topology, you will not get a uniform thickness of inflation near where the triangular Face A touches the inflation face. Instead, the number of layers of inflation at the point where Face A meets the inflation face will be reduced to zero; as one moves away from this point, the number of layers will increase by 1 in successive elements, until it reaches the number of layers that you requested.
There are two ways of overcoming this problem:
Redefine the non-inflated faces to be inflated ones. In this case the inflation will cause elements to be produced normal to these faces, and the problem does not arise.
You can edit the non-inflated faces by merging them, and so removing one of the internal edges. One way to merge the faces is to make use of the Merge Topology feature in DesignModeler; another way is to use the Virtual Topology feature in CFX-Mesh.
