Y+ calculation

[parisipa]

Hello all,

Has anyone found a way to calculate the y+ of your mesh in BaramFlow?

Hello @parisipa.
This is Donggyu from NEXTFOAM. Thank you for your interest in BARAM.

We have the plan for monitoring y+. We also know that it's important to monitor y+ for turbulence users.
So could you just wait until we implement it?

Thanks

Regards

Hi all,

In case anyone encounters this thread with the same question, you can use the following solution:

echo "functions { yPlus1
{
// Mandatory entries (unmodifiable)
type yPlus;
libs (fieldFunctionObjects);

// Optional (inherited) entries
writePrecision  8;
writeToFile     true;
useUserTime     true;
region          region0;
enabled         true;
log             true;
timeStart       0;
timeEnd         1000;
executeControl  timeStep;
executeInterval 1;
writeControl    timeStep;
writeInterval   1;

}}" >> system/controlDict

When you calculation runs, open a linux terminal (or WSL) and get into the case directory. Use this command to manually add the y+ function to the controlDict while your simulation runs.

Thank you very much.
