Hi,

I have a rectangular domain where I ignite it in the middle. This rectangular block has uniform flow through it. The problem I'm having is I don't know how I could specify the region to patch since the flow through the domain is uniform. Is it possible to somehow define a particular region (in terms of the x,y,z coordinates) where I could specify for example temperature values?

If this is not possible I was wondering if I could initialise a heat source term in FLUENT, whereby initially I could raise the temperature in the ignition region using a UDF.

Thanks
