Gradient calculation for axisymmetric simulation

Wouated · August 8, 2019, 01:20

Hi everyone,
I need to create a user field function that uses the mass fraction gradient but I get the message : " Gradient calculation not supported on axisymmetric regions " .
Is there any way to still compute the gradient value ?

Thanks,
Etienne

you should be able to define a field function to do it, I would think.

Update: I am an idiot. You already stated as much. Not sure how to definite it, you should be able to do it though.
