Detailed Description

Limits the maximum velocity magnitude to the specified max value.

Usage

Minimal example by using constant/faOptions:

<faOption>
{
    // Mandatory entries
    type            limitVelocity;
    active          yes;
    selectionMode   all;
    max             <maxValue>;

    // Optional entries
    U               <UName>;

    // Inherited entries
    ...
}

where the entries mean:
