hello

i am a beginner of fluent. Hope to obtain your help!

i want to simulate the concentration of toxic gas and airflow pattern in a building(toxic gas is released through a inlet into the building). Would you like to tell me:

1)what kind of model should i use in fluent? can i choose species transport?

2)how to obtain the plot of airflow pattern?

3)how to set the boundary conditon?

4)what is trajectory?
