Incompatibility between 2 boundary conditions in Pitzdaily case
I've just noticed something weird in the 0-directory for the velocity U:
referenceField uniform (10 0 0);
fluctuationScale (0.02 0.01 0.01);
value uniform (10 0 0);
inletValue (0 0 0); // I thought it was (10 0 0) no ?
value (0 0 0);
Indeed, I can't understand this latter, although the inlet velocity is defined by (10 0 0), we use a different one for the outlet BC.
Does anybody know the reason ?
Moreover I don't know why we have to specify the keyword ''value'' ? besides, in some cases it doesn't appear.
Thank you in advance!
The inletValue in the inletOutlet boundary condition specifies the inflow velocity at your outlet - normally you want it to be zero to prevent inflow.
Thank you for answering so quickly,
nevertheless, I've seen the documentation for "turbulentInlet" and it doesn't specify anything about the keyword "value", so what is the purpose of it ?
Same question concerning "inletOutlet", because there is no change when we delete it.
By looking at the U file at other time, I think, value specifies the velocity at ascribed path. so, at time 0, the inelt velocity is uniformly 10, but it varies for other time.
yes, I think so as well.
