Hello World.

I'm working with a combustible particle in the Discrete Phase Model.
I have switched on Species Transport Model and Surface Reaction for the Coal Particle (which I have initialized with the Coal Caluclator).

When I am post processing the particle I see that the particle law reaches no. 5, corresponding to the surface combustion. This is exactly as planned, BUT the law is never finised - so I suppose the particle is either burning very long, or not burning at all (because the char fraction is not changing after reaching the surface combustion law).

Any ideas whats wrong?

S.

I faced the same issue as well. Does someone know how to fix this problem?

I was so blind when I had this problem.
I forgot to initialize the oxygen species in the flow field.
So, without oxygen there was no combustion ;-)
