CFD analysis of packed bed reactor with porous catalysts
 

Hi,
Looking for assistance in how to create a hemisphere (type= real) in ansys gambit.
Also what are requisites to define a spherical face as porous in gambit and also accepted by fluent6. Actually when define so error received is as:

"Inappropriate zone type (porous_jump) for one-sided face zone 4.Changing to wall."

in the error it occurs

"Cannot change porous_jump.9 to porous-jump because
there is only one adjacent cell thread."

Can anybody please say how to rectify these errors and what do they imply

you can create with rotate a semicircle in gambit.it is very easy.for defining porous jump boundary you should have a boundary like interior(i.e. this boundary must have in both side cells zone) , so you should make a zone about this hemisphere and indisputable it has a fluid.
