how to set the airflow direction

[yuyachannpo]

Hello everyone,

I would like to simulate the air distribution in a room using the following FDS Codes.
But I am unsure how to set the airflow direction. Could you please give me some help me?
&SURF ID='BLOWER', VEL=-5, TMP_FRONT=50. /
&OBST XB= 0.0, 0.2,3.2, 3.6, 2.0, 2.2 /
&VENT XB= 0.2, 0.2,3.2, 3.6, 2.0, 2.2,SURF_ID='BLOWER',COLOR='RED' /

Thank you very much.

Best regards,
