Hi everyone,

I am facing a case where I would like to change velocity field in a special position throughout solving time. I use funkySetFields as follow:

funkySetFields -field U -expression "U+vector (1,0,0)" -time ':2' -keepPatches -condition " pos().y > 0.48"

However, velocity fields despite being defined correctly in the beginning, gets modified based on equations in later time points.

Therefore, I would like to ask how one can modify a field in a time-dependant manner?

Thanks and best,
Shayan

Dear shayan
if i understand your question properly, if you want to manipulated internalField you can use manipulatedField, but if you want to manipulated boundary condition, you should use groovyBC
