How is SPH Adaptive Size different from standard SPH in Ansys FreeFlow?

In standard SPH simulations:

• All SPH elements have the same size and spacing.
• Resolution is fixed throughout the simulation.
• Improving accuracy requires globally reducing SPH elements spacing.

With SPH Adaptive Size:

1. Element size can change locally during simulation.
2. Resolution is higher only in selected regions or near boundaries.
3. The overall number of elements can be significantly reduced compared to a uniform fine-resolution model.
4. As a consequence of a lower number of SPH elements, the simulation execution time can be reduced.
