DOI: 10.1063/5.0256668
Abstract: A continuum-particle coupling approach based on Bayesian regression, the micro–macro-surrogate-sparse method, is presented. In contrast to the domain-decomposition technique, we use Bayesian linear regression to infer constitutive and boundary-condition corrections from limited direct simulation Monte… read more here.
