Correct answer: A
Adaptive grids (used in numerical methods, PDE solving, image processing, CFD, etc.) adjust the grid resolution dynamically depending on the solution behavior. They aim to balance: Accuracy → higher resolution where needed
Efficiency → avoid unnecessary computation in uniform regions
Hence, adaptive grids provide high accuracy while maintaining computational efficiency . Adaptive grids dynamically adjust grid resolution based on solution behavior.
Regions with rapid changes or high gradients use finer grids for better accuracy.
Regions with smooth or uniform solutions use coarser grids to save computation.
This approach reduces unnecessary calculations compared to uniform grids.
Adaptive grids are widely used in numerical methods, PDE solving, CFD, image processing , and simulations.
They provide a balance between high accuracy and computational efficiency .
Adaptive grids also help in reducing memory usage and execution time .
