  What are the main benefits of using SPH Adaptive Size, and what types of applications benefit most from it?
  
  Key benefits include:
  Improved accuracy in critical flow regions;
  
  Reduced computation time compared to uniform fine resolution;
  
  Lower memory usage, especially for large 3D problems.
  These advantages are most noticeable in problems with localized flow complexity.
  
  SPH Adaptive Size is particularly useful for:
  - Nozzles and spray flows;
  - Free‑surface impacts and splashing;
  - Hydraulic components and valves;
  - Flows over complex obstacles;
  - Narrow gap or clearance flows (e.g., e‑motor or lubrication cooling).
  Any application where high gradients exist only in limited regions is a strong candidate.
