Sub domains?

February 22, 2008, 14:59

Hi, i have a question regarding a model i am trying to build in cfx. Basically I am modelling the dam break problem using a VOF method. The basic models are running ok, however i am now trying to simute the DBP using 2 volumes of water (ie the large normal volume and a smaller volume which will be encompased when the larger volume collapses). My "gut" feelings would be to use a subdomain, but I have never used these before. Is this the correct way of doing this or does someone know of a better method. thanks Chris

Hi,

Why are subdomains required? A subdomain may be useful to define the initial condition.
