Hi,

1) I want to give time dependent mass flow inlet as BC. below is the conditions.

Total physical time is 1.0 s
Mass flow inlet starts @ 0.2 s and ends @ 0.6 s

Can somebody guide me how to give this ?

2) Also for first 0.2 s i want to use 0.0001 time step.
From 0.2 to 0.6 s i want to use 5.0 e-06 time step.
from 0.6 to 1.0 s i want to use 0.0001 time step.

Can somebody help me in this ?

Thanks,
Arjun
