mech.dat file for hydrogen-air combuston

I am doing simulation on hydrogen air combustion characteristics.
But i am having difficulty finding the mech.dat file for simulation in converge. Can someone suggest some credible sources to obtain such files?

Hello and thanks for your question. The hydrogen sub-mechanism of the C3 mechanism is available directly from Converge Studio, in: Chemistry tools -> C3 Mechanism -> Fuel Species: H2 (Hydrogen). To use a different mechanism, there are quite a few sources online supplying a mech.dat and therm.dat, though they are not bundled directly into Converge Studio, they can be imported through the "read file" option. Please let us know any time if you have any other questions.

Best regards,
David
