Hi all,

I am facing some irregularities in my result of pressure drop.
Actually I have 5 fluid domains - inlet pipe,inlet tank,core(porous medium),outlet tank,outlet pipe.

Pressure drop in outlet tank should be lower than inlet tank.
Problem is
the pressure drop is higher in outlet tank.

Pressure drop calculated between inlet tank entry pressure to core inlet pressure i.e.inlet tank pressure . As viceversa for outlet tank pressure.. core out pressure to outlet tank out pressure.

But my fine mesh quality and mesh size also good. Iam using cyclicAMI noOrdering transform for this case.
Is this any problem with assigning of cyclicAMI boundary conditions in ( U,p,T,k,E,nut) ? May i know why this problem occurs?????

Thank you in advance,
Vishsel.
