Hello,

First, thanks for all the useful threads in this forum!

I got an odd result. Why are two reactions occurring at the same place in a fluid although they shoudln't?

According to the 'reactions' file I specified, each reaction should only occur when certain species are available.
But the Openfoam result shows that everything happens at the same time without even taking in account the necessary species.

How is that possible? Am I missing something?

The reactions file :

reactions
{
    1stReaction
    {
        type     irreversibleArrheniusReaction;
        reaction     "GLUC + GDH = 2H";
        A        5.2e16;
        beta     0;
        Ta       15;
    }
    2ndReaction
    {
        type     irreversibleArrheniusReaction;
        reaction "4H + O2 + LAC = GLUCAC ";
        A        5.2e16;
        beta     0;
        Ta       15;
    }
}

Actually it was purely a numerical error. Increasing the mesh density and lowering the time step solved it all.
