Summary0001943: Boundary condition uniformInletOutlet does not update its value in time.
DescriptionIn transient case, I have used boundary condition uniformInletOutlet with values read from .csv file and I found, that it does not update its value over time, the inlet value is still the same. When I restart the computation from non-zero time, in first iteration the boundary condition sets the proper inletValue from my .csv file, but then again it stays the same for the rest of the computation.
I did inspect the source code for the boundary condition and I believe that in file uniformInletOutletFvPatchField.C in function Foam::uniformInletOutletFvPatchField<Type>::updateCoeffs() there needs to be something to update refValue. For myself, I fixed it by adding following two lines of code in Foam::uniformInletOutletFvPatchField<Type>::updateCoeffs():

const scalar t = this->db().time().timeOutputValue();
this->refValue() = uniformInletValue_->value(t);
Steps To ReproduceRun arbitrary transient case with uniformInletOutlet condition working in regime of fixedValue, where inletValue is time dependent and it is read from .csv file.
TagsNo tags attached.
