Detailed Description

Calculates and applies the random OU (Ornstein-Uhlenbeck) process force to the momentum equation for direct numerical simulation of boxes of isotropic turbulence.

The energy spectrum is calculated and written at write-times which is particularly useful to test and compare LES SGS models.

Note This random OU process force uses a FFT to generate the force field which is not currently parallelised. Also the mesh the FFT is applied to must be isotropic and have a power of 2 cells in each direction.

Usage

Example usage:

OUForce
{
    type    OUForce;

    libs    ("librandomProcesses.so");

    sigma   0.090295;
    alpha   0.81532;
    kUpper  10;
    kLower  7;
}
