I have 2 geometry 1 pipe and 2 fluid that flow in tube.i sketched it in DM. i use from Ansys Mesh. in ansys mesh i define 3 face as inlet outlet and body of tube.but when export to fluent i see this situation as boundary condition

body of tube
outlet
inlet
fluid
solid
interior-fluid
interior-solid
wall-fluid
wall-solid

everything which is 3d is considered as interior-fluid...
