public subroutine brn_init(n, nblks, mth, f, e)

Performs initial setup.

Arguments

Type IntentOptional AttributesName
integer, intent(in) :: n

Size of the mobility matrix.
integer, intent(in) :: nblks

Number of B.dW vectors to generate for the same mobility matrix. 1 <= nblks < n.
character(len=4), intent(in) :: mth

Method for calculating the Brownian terms. mth = 'CHOL' for Cholesky decomposition; mth = 'LANC' for KSP-based method.
integer, intent(in), optional :: f

For KSP-based method, maximum number of iterations. Must be present if mth = 'LANC'. f must be less than n.
real(kind=rp), intent(in), optional :: e

For KSP-based method, error threshold for convergence. Must be present if mth = 'LANC'.
