Detailed Description

CP2K transport environment and related C-interoperable types.

History: 05.2013 created C-interoperable matrices [Hossein Bani-Hashemian] 07.2013 created transport_env [Hossein Bani-Hashemian] 11.2014 revised into CSR matrices [Hossein Bani-Hashemian] 12.2014 merged csr_interop and transport [Hossein Bani-Hashemian]

Function/Subroutine Documentation

subroutine, public transport_env_types::transport_env_release ( type(transport_env_type), pointer transport_env )

releases the transport_env

Parameters

[in,out] transport_env the transport_env to be released

Definition at line 138 of file transport_env_types.F.

Here is the caller graph for this function:

subroutine, public transport_env_types::csr_interop_nullify ( type(cp2k_csr_interop_type), intent(inout) csr_interop_mat )

nullifies (and zeroizes) a C-interoperable CSR matrix

Parameters

[in,out] csr_interop_mat the matrix to be nullified

Definition at line 177 of file transport_env_types.F.
