Hi Rob, Thank you for your reply.

I didn't see anything by plotting UDM0.

but I found the species concentration gradient is calculated. I don't know how this happens (I have difficulty in understanding how the UDF works.).
but I didn't find the magnitude of gradient, although the code has done the calculation. C_UDMI(c,t,0) = NV_MAG(C_UDSI_G(c,t,0)); 

it seems the forum didn't send email to remind me that I get reply anymore. I don't know why this stops.

thank you again.
