Kawa46 is on a distinguished road
Hi everybody,

I need help about the evaluation of the spatial gradient of a udf passive scalar by user subroutine..is there a function that allows this? Following the manual i've founded only the access to velocity gradient (by the variables DUDX,DUDY and so on)

Thanks
