Hello everyone,
I am looking into reactingTwoPhaseEulerFoam and I am trying to find out how to implement some simple chemical reactions in to a case of modelling a circulating fluidised bed cold model. The case has been modeled succesfully with twoPhaseEulerFoam. My starting point is to look at the tutorial bubbleColumnEvaporatingReacting (Openfoam 3.0.1) and replace the liquid phase with particle phase. I only changed the initial values and phaseproperties to represent the partclee phase. I did no modifications to the reactions in constant/chemistryProperties.gas, constant/reactions.gas and constant/thermo.gas. My idea was to first make the tutorial case work with particle phase instead of liquid phase and after that try to add a more meaningful reaction. I managed to set up the case so that it starts calculation, but it stops as soon as it starts to calculate the volume fraction of CO.gas. Here is the log: Code:

Hello, I know this is an old post, but did you manage to get this working? I am currently having the same issue. I would greatly appreciate any feedback
