摘要: Abstract We present a simple method for the numerical calculation of noise distribution in multicomponent functional Langevin models. The topic is considerable importance, view increased interest application mesoscopic dynamics simulation models to phase separation complex fluids polymer and surfactant industries. show that computational methods can be derived few (non)linear cases. analysis contains three distinct steps: (1) factorization diffusion operator, (2) generation auxiliary random fields (3) Cholesky decomposition mobility operators.
