inletvalue and value in inletoutlet BC
what are inletvalue and value must be assigned for inletoutlet or outletinlet BCs?if inletvalue is velocity whats value?

value is just a default value that will be changed at runtime and calculated.
inletValue is the value of the velocity when the flux is negative at the outlet, i.e. inflow.

then value isn't important and relates to inner calculations of openfoam?could it be set as (0 0 0) for convenience?

yes, you can set it to


value uniform (0 0 0);
for examples, you can search in the tutorials directory with


grep -R "inletOutlet" .

thank you dan.whats about calculated BC?as instance density in perfect gas solutions can be set as calculated?if we dont set it so how can we draw its field with paraview after solve?
And If we determine a value in this kind of BC it has any effect?
Thank you again so much.
