Turbulent combustion error... XiFoam model
 
Hi,
I am working on Gas turbine combustion simulation. I tried to use XiFoam model. The following error was displayed.

Create time

Create mesh for time = 0

Reading combustion properties


Ignition switched off

Reading g
Reading thermophysical properties

Selecting thermodynamics package hhuMixtureThermo<homogeneousMixture<sutherlandTran sport<specieThermo<janafThermo<perfectGas>>>>>
min(b) = 1

Reading field U

Reading/calculating face flux field phi

FOAM aborting

--------------------------------------------

There is a problem with dimensions. I am not able to locate it as I am new to OpenFOAM. Could someone please locate the problem?

Thank you,

you did an error in the input dimensions!
a typical case is when you copy the Bc from an incompressible case to a compressible one.. in these two cases the pressures are measured in a different way (one is scaled by the density).
i hope i helped you!
cheers
