 July 10, 2013, 07:33 janafThermo Warning #1 New Member   Luca Franceschini Join Date: Aug 2012 Posts: 29 Rep Power: 6 Hello, l have modified the turbulentTemperatureCoupledBaffleMixedFvPatchScala rField BC in order to include a surface source term. My results seems reasonable but Foam keep giving me the warning: --> FOAM Warning : From function janafThermo::limit(const scalar T) const in file /home/OpenFOAM/OpenFOAM-2.2.x/src/thermophysicalModels/specie/lnInclude/janafThermoI.H at line 108 attempt to use janafThermo out of temperature range 200 -> 5000; T = 5497.566 Clearly at one point the solver sees temperatures higher than 5000... My problem is that i do not understand where this happens. If i plot the results the maximum temperature that i have in the filed and in the patch is of around 1100. As also proved by the log : Min/max T:min(T) [0 0 0 1 0 0 0] 300 max(T) [0 0 0 1 0 0 0] 1096.741 Does anyone knows where there may be the problem? Thank you in advance for any help, hint or suggestion

By the way, how do you check the max. temperature. Are you using the "max" or the "gMax" function? Christian

I solve U, Y and E in order and i get this warnings just after the solution of U. Best... Thank you a lot
