Blender uses position-based dynamics with a mass-spring system with discrete collision detection, it is fast, however is less accurate. HiPhyEngine uses finite element discretization with continuous collision detection. HiPhyEngine's simulation result is more physically accurate, and guarantees intersection free, even with complex and multi-layered collisions, and no matter how fast an object is moving, or how thin it is.

HiPhyEngine's finite element discretization has the benefit of resolution independence. Using lower resolution simulation for iterative parameter tuning in HiPhyEngine will guarantee the same large scale behaviors when increase the simulation resolution.

HiPhyEngine is parallelized and vectorized to fully utilize all CPU cores. Even with the complex collisions, each frame will only take seconds.

HiPhyEngine gives user full artistic controls. Most simulation parameters can be animated and mapped. In Blender, user can utilize attributes and geometric nodes to create animated simulation parameter maps for HiPhyEngine. HiPhyEngine also provides integration with the expression language SeExpr2 to give user more ways to create force fields and attributes.

HiPhyEngine is a fully coupled physics simulation engine for five different material models. Need to couple cloth and rigid body? Cloth and hairs? Soft bodies? No need for the extra set up! HiPhyEngine will take care of all the interactions!

HiPhyEngine guarantees intersection free simulation. No matter how fast things are moving, how thin, if there is a intersection-free solution, HiPhyEngine will find it! To give user maximum control, user can use animated maps to activate/deactive collision on demand anywhere, at any frame.

Gravity is pulling your carefully groomed hairs down? No worries! HiPhyEngine has an inverse simulation technique that automatically generates the rest shape that compensates for gravity and other external forces. Animators are handing you meshes that go through themselves? HiPhyEngine's soft collider feature will automatically clean up incoming animation mesh makes them intersection free and ready for simulation. HiPhyEngine also has solver space, unit conversion, time scale, and tons of other features to explore!

HiPhyEngine also provides a MPM solver, that is capable to simulate variety of phenomenons with fluid/solid mixture, such snow, sand, mud, or even bread dough!
