janafThermo warnings with ICE RCCI combustion simulation

Hello,
I have a question regarding multiple warnings I'm receiving during my OpenFOAM simulations. I constantly encounter FOAM Warnings about janafThermo being out of temperature range (so temperature being below 300 [K]). A little background on my project. I'm trying to simulate RCCI combustion within an ICE, using IC8H18 as a low reactive PFI fuel and NC12H26 as a high reactive DI fuel. This engine is simulated from crankangle -153 aTDC till 150 aTDC. For the boundary conditions at crankangle -153 I used GT-Power to determine the conditions like pressure, temperature etc. The solver which I'm using to simulate is a solver from the LibICE library, called TDACCCMdieselEngineDyMFoam. Everytime I run my case I get these janafThermo warnings and after a while the simulations stops with errors. I tried different cases using different boundary conditions, but still the temperature diverges beyond the temperature range. I also tried reducing my time step for the simulation, still the same problem. I was wondering if anyone could help me out ? I'm fairly new to OpenFOAM as this is my first time working with OF. Thanks |
