OUTLET in domain
 

Dear all I have 2 queations: 1)I want to kown what is the 'High' or 'Low' side meaning about the OUTLET in domain. And in this case, if the OUTLET likes a mass 'source' or 'sink' ? 2)my OUTLET is greatly 'small' in size(about 1/500 size of domain),i have already refine the grids around it, sould that still bring me large error? thanks

Re: OUTLET in domain
 

OUTLET will just try to fix the given pressure at its location and no need to worry about source/sink. since u have fine grid , u shouldnt face any problems.
