UDM gradient
 

is it possible to compute gradients of UDMs (user defined memory) during the run?
I have to further use the gradients within the UDF only. Defining the variable as a UDS surely computes the gradient (C_UDSI_G) automatically, but then extra transport equations for the said UDS are also solved.

Can anyone please tell me how to compute gradients of UDM?

thanks.
