fshak92 is on a distinguished road
I need to simulate a laser beam using radiation.
For example in the sample case you can see in the picture,i need to have radiation in a single patch(small width) from the above thin surface, to the below surface like a laser.
In Fluent, we can use DO method, to simulate a beam.
But using DOM in StarCCM, give me a surface to surface radiation.
Does anybody know how can i simulate small width in specified direction in star ccm?
