Hi everybody,

Quick question: Does fluent allow parallel processing in a DO radiation model ?

Thanks

yes we can do "do radiation model" in parallel

Generally yes, but in this moment I have a problem to run one case with DO in parallel:

It requirs more memory in parallel also. So best way to use is "Solve radiation for every 2/4 flow iterations." Check for this option in radiation panel.

Iterations without DO equations solving works without problem. Iteration with DO equations solving gives me the error. And, probably I have enough memory... I have discussed the problem with Fluent user support without success...
