+### BET Metrics Output Variables
+
+The `betMetrics` and `betMetricsPerDisk` output fields provide Blade Element Theory (BET) metrics for analyzing rotor and propeller performance. These fields are available when using BET models in volume zones. The `betMetrics` field includes data from all BET disks with possible overlapping, while `betMetricsPerDisk` provides separate outputs for each disk to avoid overlap.
+
+The following variables are included in the betMetrics output:
+
+1. **`VelocityRelative`** – Relative velocity with respect to the rotating reference frame (non-dimensional).
+
+2. **`AlphaRadians`** – Local angle of attack in radians.
+
+3. **`CfAxial`** – Axial aerodynamic force coefficient.
+
+4. **`CfCircumferential`** – Circumferential aerodynamic force coefficient.
+
+5. **`TipLossFactor`** – Factor to model the effect of blade tip.
+
+6. **`LocalSolidityIntegralWeight`** – Local solidity multiplied by the integral weight.

 ### Hybrid RANS-LES Output Variables
 
 The `SpalartAllmaras_hybridModel` and `kOmegaSST_hybridModel` output fields provide diagnostic variables for hybrid RANS-LES simulations. The specific variables included depend on whether you're using **DDES** (Delayed Detached Eddy Simulation) or **ZDES** (Zonal Detached Eddy Simulation) as the shielding function.
