How to find the index of the nearest wall face?
 

Hi guys,

I know that if I call wallDist, I will get a y field with values of the nearest wall distance. Now if I select a mesh point in the field, how do I know which wall face index of this point's nearest wall distance with respect to? Thanks very much in advance!

Regards,
Jack

BTW: I know that I can loop over all the wall faces and find out the index in serial. But in parallel, this calculation is really trick. I am wondering if there is a built-in function that can do the job.

Any solution?

Hi Jack,
can you tell me an easy way to compute the walldistance field only for the timestep "0"?

David

Hi Jack,

Did you have the solution for this? If you have, please share it to me.

Thanks in advance,
