### 15.5.2. High Resolution

With this setting, the blend factor values vary throughout the domain based on the local solution field in order to enforce a boundedness criterion. In flow regions with low variable gradients, the blend factor will be close to 1.0 for accuracy. In areas where the gradients change sharply, the blend factor will be closer to 0.0 to prevent overshoots and undershoots and maintain robustness.

Note that for vector quantities it is the components that are bounded between 0 and 1. Therefore, the magnitude of for a vector quantity can be as large as .
