Description

The databases contain the inertial stress tensors for the equilibrium state of DNS simulations of an RVE for given Id1 (and Id2). For more details see (paper in revision).

Steps to reproduce

Inputs: Id_{ij} = G_{ij}H^2/nu for a pure shear configuration of gradients G. Outputs The nine components of the fine inertial stresses tensor <uf_i*uf_j> where <.> indicates temporal mean of spatial average, and uf is the perturbation of the RVE solution uR, this is uR_i = G_{ij}*x_j + uf_i.
