Transient simulation
 

Hi every one
I have a problem with transient simulation, when I use steady simulation for my system (thermal energy storage system in packed bed of rocks ) it works normally (I talk about temperature decrease in the tank) but when I choose transient simulation I obtain anormal results
can someone help me please

Which solver you are using? What kind of transient scheme you are used.

I use ansys fluent 16
about what transient scheme ,I can't understand because am a new user of ansys fluent
