Hi Fluent Gurus,

Is there a way to access (call) dimensions of your geometry, eg. radius of an inlet section, from within the udf? I have searched the entire UDF manual and found nothing.

Thanks in advance.

Regards,

John

No direct macro to return inlet radius, but you can loop all the node on inlet and calculate the maximum distance between two nodes. This is just the inlet width.

Hi Ji,

Thanks for the reply. I went ahead and calculated the radius from the area by adding up the face areas within the inlet face thread (I was performing an area-weighted average of pressure and velocity at the inlet). I initially thought of your idea, but my code is already bogged down with multiple loops and I didn't want to slow it down any further with additional loop and condition statements. Thanks for you input thought, I appreciate it.

Cheers,

John
