Hi everybody.
I model simple bunsen flame with pilot by xifoam solver of openfoam 1.4.1. but tempreture in some cell (in premixed core) is lower than 300k and finaly it aborted by out of janafthermo error.(my lowest Tin boundary is 300k)
I do anything such as low curant number(co=0.1) , finner mesh, chaneg tolerance, increese piso corection, channg discretization scheme,... but is not benefit and abort by that error.
Can someone help me?
if anyone havw a case by this solver please send me.
Thanks a lot.

Tavasoly, You can make a ca
 

Tavasoly,

You can make a case for XiFoam by modifying the Xoodles tutorial case, $FOAM_TUTORIALS/Xoodles/pitzDaily.

You will also need copy information from:
"constant/turbulenceProperties"
"system/controlDict"
"system/fvSchemes"
in $FOAM_TUTORIALS/XiFoam/moriyoshiHomogeneous and copy "0/epsilon" from $FOAM_TUTORIALS/simpleFoam/pitzDaily

Also, a schematic of the problem/system you are trying to solve might help the readers of the forum provide additional strategies to stabilize the simulation you are currently working on.
