Please could someone explain me the reason why the simulation is not running?

I am working with OpenFOAM-v1912 and using reactingTwoPhaseEulerFoam solver. I am applying reactingTwoPhaseEulerFoam tutorial (laminar fluidised bed) modified using chemistry from other reactingTwoPhaseEulerFoam tutorial - bubbleColumnEvaporatingReacting.

Here is the result I got:

After that the simulation is stopped.

Who knows the reason or at least possible reason your suggestions are highly appreciated.

can you share your phaseProperties-file input?

well, from your first post, i can see that the solver stops when the phaseproperties dict is been read.
i can't judge if you incorporated everything correctly though.

the simulation doesn't even start, so i won't think that its something related to BC's or IC's.

if something you entered is not in the options list, then openfoam should normally tell, which options are possible.

those crashes without any error output are hard to find the origin of the failure.

i suggest that you start with the example tutorial and then change the settings step by step.at every new step run the solver just to see if it stops working or if its continues. it will be easier to find the cause.
