Hey,
I'm calculating a coal combustion with fluent, but I noticed that there are no Residuals plotting for energy.
The solver just writes a nan instead of an Number. The energy equation is enabled so I have no clue why it won't calculate.
Does anyone has an idea?

Thanks

No one? I also noticed that the energy residuals show up as soon as I disable the species transport.
I'm really confused

Ok never mind, the problem seems to be with the UDF's for the absorption.
