Hi there, i have a solidworks based final year project, mainly flow simulation and FEA analysis, i have made a wind tunnel for my wind turbine which is sealed from all the sides, both sides with seperate lids, and when i try to do the flow simulation, the computational domain does not fall on the lids (it does not recognize the lids) it forms on the wind turbine or the assembly, and when i try to manually extend the computational domain on to the lids, this error occurs " Face@LID7-1 is not laying on the boundary between solid and fluid region error
