sigma_cpu Module Reference

Implements the CPU kernel for the sigma_t type. Following Nicoud et al. "Using singular values to build a subgrid-scale model for large-eddy simulations" https://doi.org/10.1063/1.3623274.

Functions/Subroutines
subroutine, public	sigma_compute_cpu (if_ext, t, tstep, coef, nut, delta, c)
