How to set up a hydrogen combustion reaction

[gdut21122]

In reactions, select Add From Library, and select HYDROGEN. In Fuel Species, select HYDROGEN or REAC-FUEL.At the same time, why the hydrogen combustion reaction temperature I set is very low, only tens of degrees, is the reason not to produce smoke?

1. I guess you refer to Pyrosim interface.
2. What value do you refer in terms of FDS parameter?
3. Do you mean soot by smoke?

Make sure you have read all of the FDS (and not just Pyrosim) documentation. This is the first source of information for questions on FDS.
