Transient UDF
Hi there. i wanna ask a question about making of a time-dependent user defined function.

i have a 2d case which has 2 cell zones. Solving it laminar since inlet speed is slow enough.

i want to set an udf regarding cell-zone temperature fixed value. i want that valueto be fixed at 500K for 0.5 seconds, and then cease it's fixed temp. effect.

how can i do it? i've already tried DEFINE_ADJUST to set temperature of its cells manually (by cellzone ID and interior part ID) ,it won't work, and tried to use DEFINE_PROFILE too.

You do not have to use UDF. Use the fixed value option of zones from the GUI.

not really,
i need to use udf because i need a time dependent fixed value. i need udf to set fixed value to 500k then set it automatically to "none".

is there any way of doin this ???
