I have read all the previous threads on source term addition.

My problem is this....

I have to add a source term in the mass conservation equation. This source term is a function of local 'y' co-ordinate and also local 'Uy' (y-component of U)
Lets say, for example....
ddt(rho) + div(phi) == -(rho*Uy)/y


How to add this source term on the right hand side

What I meant is, I still couldn't figure out how to get the y co-ordinates in an array, so that i can manipulate to the right of the equation....

Can any one elaborate on this. Awaiting a reply

Hi Aurun

Please note that the components run from 0, thus:

x:= component(0)
y:= component(1)
z:= component(2)

with := meaning defined as.

Best regards,

Niels
