How is it possible to have a p0 and T0 boundary condition without having velocity field at inlet in groovyBC?just these stagnation properties are known.its important for me.sorry for repeat.

thank you treima
But I think velocity should read from outside of the grid domain.due to characteristic law you may know that tell at inlet 5 property should be assigned from out and only 1 from inside the domain and vice at outlet for stability of solution.
But velocity have 3 components
But ill examine your good suggestion if it didn't have stability problem all is ok.
Thanks.
