FishGym: A High-Performance Physics-based Simulation Framework for Underwater Robot Learning
Wenji Liu, Kai Bai, Xuming He +3
Bionic underwater robots have demonstrated their superiority in many applications. Yet, training their intelligence for a variety of tasks that mimic the behavior of underwater cre…
GPU Optimization for High-Quality Kinetic Fluid Simulation
Yixin Chen, Wei Li, Rui Fan +1
Fluid simulations are often performed using the incompressible Navier-Stokes equations (INSE), leading to sparse linear systems which are difficult to solve efficiently in parallel…
Vectorizing Quantum Turbulence Vortex-Core Lines for Real-Time Visualization
Daoming Liu, Chi Xiong, Xiaopei Liu
Vectorizing vortex-core lines is crucial for high-quality visualization and analysis of turbulence. While several techniques exist in the literature, they can only be applied to cl…
Phononic Helical Nodal Lines with Protection in MoB
T. T. Zhang, H. Miao, Q. Wang +9
While condensed matter systems host both Fermionic and Bosonic quasi-particles, reliably predicting and empirically verifying topological states is only mature for Fermionic electr…
Dynamic Upsampling of Smoke through Dictionary-based Learning
Kai Bai, Wei Li, Mathieu Desbrun +1
Simulating turbulent smoke flows is computationally intensive due to their intrinsic multiscale behavior, thus requiring relatively high resolution grids to fully capture their com…
Continuous-Scale Kinetic Fluid Simulation
Wei Li, Kai Bai, Xiaopei Liu
Kinetic approaches, i.e., methods based on the lattice Boltzmann equations, have long been recognized as an appealing alternative for solving incompressible Navier-Stokes equations…
Towards High-quality Visualization of Superfluid Vortices
Yulong Guo, Xiaopei Liu, Chi Xiong +2
Superfluidity is a special state of matter exhibiting macroscopic quantum phenomena and acting like a fluid with zero viscosity. In such a state, superfluid vortices exist as phase…
Relativistic superfluidity and vorticity from the nonlinear Klein-Gordon equation
Chi Xiong, Michael R. R. Good, Yulong Guo +2
We investigate superfluidity, and the mechanism for creation of quantized vortices, in the relativistic regime. The general framework is a nonlinear Klein-Gordon equation in curved…
