Parameter-free inexact block Schur complement preconditioning for linear poroelasticity under a hybrid Bernardi-Raugel and weak Galerkin finite element discretization
Weizhang Huang, Zhuoran Wang
This work investigates inexact block Schur complement preconditioning for linear poroelasticity problems discretized using a hybrid approach: Bernardi-Raugel elements for solid dis…
MCTR: Midpoint Corrected Triangulation for Autonomous Racing via Digital Twin Simulation in CARLA
Junhao Ye, Cheng Hu, Yiqin Wang +6
In autonomous racing, reactive controllers eliminate the computational burden of the full See-Think-Act autonomy stack by directly mapping sensor inputs to control actions. This by…
An inherent regularization approach to parameter-free preconditioning for nearly incompressible linear poroelasticity and elasticity
Weizhang Huang, Zhuoran Wang
An inherent regularization strategy and block Schur complement preconditioning are studied for linear poroelasticity problems discretized using the lowest-order weak Galerkin FEM i…
Efficient parameter-robust preconditioners for linear poroelasticity and elasticity in the primal formulation
Weizhang Huang, Zhuoran Wang
Poroelasticity problems play an important role in various engineering, geophysical, and biological applications. Their full discretization results in a large-scale saddle-point sys…
A general regularization strategy for singular Stokes problems and convergence analysis for corresponding discretization and iterative solution
Weizhang Huang, Zhuoran Wang
A general regularization strategy is considered for the efficient iterative solution of the lowest-order weak Galerkin approximation of singular Stokes problems. The strategy adds…
New finite volume element schemes based on a two-layer dual strategy
Weizhang Huang, Xiang Wang, Xinyuan Zhang
A two-layer dual strategy is proposed in this work to construct a new family of high-order finite volume element (FVE-2L) schemes that can avoid main common drawbacks of the existi…
