UDS for 2D axisymmetric
 

For 2D axisymmetric geometry, I need to check how the diffusive term of UDS tranport equation is exactely written.

I suspect it is of the form (but could find any information in the fluent doc. to confirm it):

1/r*d/dr(r*d(UDS)/dr) + 1/r*d/dz(r*d(UDS)/dz)

Thanks for your help
