Reply To: Correct CFX Pre Setup to avoid isolated fluid regions

[Kelsey O'Donnell]

Hi Mark,

I believe my issue then is that I am creating walls to separate the "mussel" geometry from the outer fluid domain. Specifically I am selecting and am setting all of those faces that make up the mussel geomety as being non-slip walls (as well as the sides/bottom of the outer enclosure). How should I set my boundary conditions so that the solid objects within the domain are seen as such with flow going around them instead of through them but are not creating isolated fluid regions?? Is there a different way I should be designating those objects?
