Numerical analysis of finite element method for a stochastic active fluids model
Applied Numerical Mathematics(2024)
摘要
In this paper, we first investigate the well-posedness and regularity of mild solution to a stochastic active fluids model driven by the additive noise. A fully-discrete scheme is proposed for solving the given model, which is based on the finite element method for spatial discretization and the backward Euler method for temporal discretization. By overcoming the difficulty of error analysis caused by the discrete Laplacian operator, we obtain the convergence results of the developed scheme. Finally, some numerical examples are privided to validate the theoretical results and we also simulate the motion states of the active fluids.
