Hi,
I too am trying to model a case with multiple ignition sites with XiFoam rans modelling but so far haven't found any data related to it. It would be really helpful if someone could tell me anything about it.

Thanks for your time,
Naman.

Hi everyone,
As to answer the question about multiple ignition sites, I have found that in XiFoam, if you copy paste the ignition sites properties there itself and mention another location in it, you can introduce more ignition sites. PFA a screenshot of how I used it to understand better.
Sounds trivial but I thought it might be of help as I was struck with this for long. Any other suggestion is appreciated but this definitely works. I hope someone in need finds this helpful.

Naman.

Just set the start and duration to get your desired ignition at 10s and 20s.
