Default UDS - Modification of the transport equation

Hi there,

I need to model a problem, where I need to add the following term to the transport equation of the UDS.

grad(1/a(UDS))*a(UDS)*grad(UDS),

where a is a function of the UDS, which i know and which is saved in a table dependend on the UDS. Do you see a possibility to add this term to the transport equation of the UDS or to get it into one of the terms for convection or diffusion.

I would be really glad, if you help me.

Greetings, Johannes.
