how to increase cores number when we use CFX and ansys solvers

hi every one !
in two- way fsi use cfx and ansys by .inp file. how to increase cores ansys solver in paralel environment .
as follows :*** NOTE *** CP = 4.056 TIME= 11:34:39
No input port number for master code; an available port will be
obtained for socket connection and it will be saved to: ANSYS.port.
Port number = 51382
Master Socket number = 1
Number of codes = 2
Slave ID: 2; Socket number = 2

FIRST SYNCHRONIZATION POINT OF MASTER CODE:
GET CODE INFORMATION FROM SLAVE CODES

ANSYS solver only use two cores .
Total number of cores available : 8
Number of physical cores available : 8
Number of cores requested : 2 (Shared Memory Parallel)
so i want to increase cores in ANSYS SOLVER .
I need everyone' help.
thank you !

The command that launches the ANSYS solver needs to include:
-np 4
for example (to solve on 4 cores). If you are starting from the CFX Solver Manager then you can type the above into the "ANSYS Arguments" field.
