pressure load at inlet
 

Hello every one,
in a transient cfd problem there is a time depndent pressure load at inlet
(like: P=sint).for this boundary condition i used CEL in cfx11.0.
which one of "atstep","ctstep" or "t" should be used as time?
regards,
s.ghassemi.

Hi,

This is discussed in the documentation. Look under the CEL Expression Language Reference guide.

Hi Siavash,

"t" is the time variable based on your initial start time and will increase with physical time steps. then using "t" as the time variable, will do it.
