I am attempting to create a mesh of a volume with a rounded cone inside. After meshing, I assign a total of 4 sidesets to the top, lateral, and side walls, and the rounded cone inside. However, when I export the mesh to fluent, a “wall_0”, in addition to walls 1-4, is automatically generated (as shown at the end of the .msh file). How can I avoid creating wall_0? Here is my journal file.
