Functions/Subroutines

subroutine les_model_init_base (this, dofmap, coef, nut_name, delta_type)
 LES model factory. Both constructs and initializes the object. More...
 
subroutine les_model_free_base (this)
 Destructor for the les_model_t (base) class. More...
 
subroutine les_model_compute_delta (this)
 Compute the LES lengthscale. For each GLL point, we take the distance between its neighbours in all 3 directions divided by 2 with the exception of face nodes, where only one neighbour exists. To form the lengthscale the distances along 3 directions are multiplied, and a cubic root is extracted from the result. This roughly corresponds to a cubic root of the cell volume in FVM computations. More...
