Replace Zone
 

Hi,
In order to model a problem of valve, i can't use the dynamic mesh method (not enough time and licence for parallele in my school)...
i want to change a solid zone into fluid zone during the simulation.
i have divided my geometry in 2 and during the simulation i change the solid zone into a fluid zone.
i change the wall into interior and i calculate again with this new configuration with a very small time step (10-13 s).
Do you know what Fluent do in this zone (what values is it in this zone when i start again the calcul)? and have you got any advice?
Thank you
