Hi foamer,

I would like to setup oscillatingFixedValue with the equation

u = 2.7 + 16(sėn2pit/16)

I saw the guide at

https://openfoamwiki.net/index.php/M...tingFixedValue

if I understand exactly, the inlet velocity will:
inlet
{
type oscillatingFixedValue;
value uniform 0; // Initialization value
refValue uniform (1 0 0); // Reference value for oscillation
offset (1.7 0 0); // Oscillation mean value offset
amplitude constant 16; // Amplitude of oscillation
frequency constant 0.0625; // frequency
}
Following the equation, I set offset 1.7 will it plus 1 to 2.7?


Thank you
Thanh
