Converged values and boundary conditions

viveksubu · July 11, 2011, 19:57

i was running a simulation and after the solution converged the results did not make sense.
the problem is that :
my inlet velocity condition is 1.96 m/s and
my outlet pressure condition is 0 guage pressure.
but the results after the convergence of the simulation did not match for either of the two , that is the inlet velocity and outlet pressure were not anywhere close to the boundary conditions.
can any1 tell me as to why that might be?

First of, your BC's cannot change during the solution, they are fixed values. I'll need more details on what you are analysing to help you.
