subdomain id

Hi all,

I tried to print the subdomain id and processor id with udf in a simulation with 8 cores.

I am not sure why subdomain id and processor id are both always 0 although I am running in parallel mode. Technically, the udf should have printed from 0 to 7. I also tested with quadrature id and it prints 0 to 7.

Can you help me identify what's going on here?

Thanks.
