What is SPH Adaptive Size in Ansys FreeFlow?<\/strong><\/h1>\n

SPH Adaptive Size<\/strong> is a capability in Ansys FreeFlow that automatically adjusts the size (resolution)<\/strong> of SPH elements during a simulation. Instead of using the same element size everywhere, you can define where higher accuracy is needed, and then the SPH solver will dynamically refine or coarsen SPH elements.<\/p>\n

The main purpose of the SPH Adaptive Sizing method is to improve computational performance for problems in which accurate physical resolution is required only in specific regions of the domain.<\/div>\n

Instead of uniformly refining the entire fluid domain, the SPH Adaptive Sizing Method<\/strong> allows higher resolution to be applied only in regions of interest. By refining SPH elements locally, while keeping a coarser resolution elsewhere, the method reduces the total number of SPH elements and, consequently, lowers computational cost and simulation time without compromising accuracy where it matters most.<\/p>\n
