 August 21, 2007, 11:16 adjacent cell zones #1 Louisa Guest   Posts: n/a Hey, When I check my grid as soon as I import it to fluent I get a message about a zone that has 2 adjacent cell zones. What does this mean? And how can I overcome this? Regards, Louisa

 August 21, 2007, 13:03 Re: adjacent cell zones #2 Joe Guest   Posts: n/a A zone has two fluid zones on either side of it. This shouldn't happen e.g. a fluid zone on either side of a symmetry plane.

 August 21, 2007, 13:59 Re: adjacent cell zones #3 Louisa Guest   Posts: n/a so what do u suggest I do to overcome this? the certain zone it refers to is the pressure-inlet from which water enters a porous zone both on the positive and negative y-direction..

 August 31, 2007, 02:55 Re: adjacent cell zones #4 Volker Pawlik Guest   Posts: n/a you mean the pressure inlet lies inside the porous zone, i.d. on both sides it is surrounded by the fluid zone of type porous? This does not work. A pressure inlet (all zones of the type inlet and outlet) can have only one adjacent fluid zone. The only way to have one inlet at the same position with the inlet normal pointing in 2 directions is to "slit" the inlet-zone via the TUI (/grid/modify-zones/slit-face-zone) into 2 zones with the same properties. Before you can do that you have to change inlet to wall, I think, unless Fluent alread did that for you. Or: The grid already mustn't be connected at the inlet position. BUT: remember that the two inlet zones do not "know" each other. They are completely independent.

I will try your sugesstion to "slit" the inlet-zone! Thank you so much! Louisa
