How to ignite defined particles

[alips123]

Hi,
In order to assess fire spread, I have defined a cube of vegetation by particles; however, I don't know how I can start ignition in that.
Can anyone help me?

Have you looked at any of the examples in the User's Guide, Verification Guide, and Validation Guide?

Hi,
What I have found in user guide was how to model particles' parameters and pyrolysis reactions, but I have not seen fire ignition of these particles.

Add a hot object under the particles.
