Properties🔗

• Applies a force to maintain a user-specified volume-averaged mean velocity, e.g. useful for channel flow cases

Usage🔗

The option is specified using:

meanVelocity1
{
    type            meanVelocityForce;
    selectionMode   all;
    fields          (U);
    Ubar            (10 0 0);
}

Currently only available to incompressible solvers
