Verifying Surface Normals in Integral Calculations

Problem: How do I verify the direction of my unit surface normal vectors to make the correct integrations? If my surface normals point in an inconsistent direction from one timestep to another, how do I correct the value of my integral? From the User’s Manual: “Integrations involving surface unit normals, such as Mass Flow Rate, and Forces and Moments integration, rely on surface unit normals pointing in a consistent direction. […]
