How to activate interface BC in sequence
 

Does anyone know how to simulate several domains exchange pressure in sequence?

one way is just to manually create the interface BC between different domains one by one, which needs to stop the simulation to change the settings.

is there any smarter way to make it automatic, so that the simulation just needs a one-time setting according to a sequence rule?

If stopping and restarting your simulation is the issue you are trying to overcome, you could just learn some scripting (i.e. record a macro) that does this so you don't have to manually stop and start during runtime.

Thanks for your reply.

This case is to simulate the instantaneous temperature in one target room, and this room is connected to three or four other sealed rooms by doors. The initial temperature in each room is different, and these doors open in sequence. So here comes the problem that if I use domains to simulate the room, how to make these domains start to exchange data at different time points.
