private

Set boundary conditions which can be: a) Wall and Symmerty BCs implemented at CompressibleFlowSystem level since they are compressible solver specific; b) Isentropic vortex and Ringleb flow BCs implemented at EulerCFE level since they are Euler solver specific; c) Time dependent BCs.

Parameters

inarray	fields array.
time	time.
