WebMay 3, 2024 · Its settings are described in the system/fvOptions file. The strength of damping is gradually increased from radius1 to radius2 and full damping is applied in the region where r > radius2. The maximum value of damping coefficient is defined as follows: \begin {align} \nu_ {max} = w \times frequency. \tag {1} \label {eq:maxnu} \end {align}
