Hello ,
Iam trying to simulate diesel+naturalgas combustion in HCCI mode. I used reaction mechanism taken from converge example case of duel fuel(diesel+ methane). Iam injecting diesel in one pulse(80 deg before tdc)and intake temperature of air and natural gas is 350k. But combustion is not happening in simulation. In experiment combustion is happening with same values.
Can I use that reaction mechanism of dual fuel for HCCI? Is this the problem ?
Kindly help.

You should find a reaction mechanism of HCCI。
Mechanisms in the example cases are not for HCCI.
