  Internal flows are defined by moving fluids surrounded by solid surfaces. For example water flowing inside a pipe.
  External flows instead are unbounded flows that move over bodies. For example air moving over a car.
  For detailed discussion on aspects of internal and external flows, check out the respective courses that are part of the Basics of Fluid Dynamics Learning Track on the Ansys Innovation Courses webpage.
