Hello,

I am using a cyclic boundary layer for an atmospheric boundary layer condition. Here I need to give a velocity profile and turbulence profile at the inlet using the fvOptions. I am currently only able to give a fixed value.

Can you please help me to input a profile, extracting the data from a CSV file, or any other way possible? I tried using the fixed profile function but I can't make it work. I could use the fixed profile option to define the boundary conditions, but can't make it work here.

Your help will be deeply appreciated.

Thank You.

With best regards,
Saugat



This is for the fixed value of velocity

momentumSource
{
type patchMeanVelocityForce;
active yes;

patchMeanVelocityForceCoeffs
{
selectionMode all;
fields (U);
patch inlet;
Ubar (0 8 0);
relaxation 0.2;
}
}

I tried this it doesn't work (its more like a wild guess):

momentumSource
{
type patchMeanVelocityForce;
active yes;

patchMeanVelocityForceCoeffs
{
selectionMode all;
fields (U);
patch inlet;
U
{
type fixedProfile;
profile csvFile;
profileCoeffs
{
nHeaderLine 0;
refColumn 0;
componentColumns (1);
separator ",";
mergeSeparators 0;
outOfBounds clamp;
file "C:\Program Files\blueCFD-Core-2017\ofuser-of5\run\manualK_20210812\0\Book2.csv";
}
direction (0 0 1);
origin 0;
}
relaxation 0.2;
}
}
