Density Gradient- UDF
 
Hi,

How can I access a density gradient for UDF purposes? Macro C_R_G(c,t) doesn't work.

I think the usage is:

C_R_G(c,t)[0] for x direction C_R_G(c,t)[1] for y direction etc.

If that doesn't work, copy C_R into a uds and then use

C_UDSI_G(c,t,uds)[0]

Thanks for Your response,

I will try to do it by UDS - but I think such macro for density gradient should exists...
