Hi everyone,

I have defined a source term for a scalar that is not a function of time and the boundary conditions are also steady while, for some reason, the simulation is transient.
The results show that this particular scalar has transient behavior while, as I said, the boundary condition and the source term do not have temporal terms.

What could be the reason?

Thanks,
Ali

you may try to calculate it only once, on the first time step


best regards

I will do it and let you know what will happen.
But wouldn't it get transported downstream if the source is turned-off after the first time-step?

if under scalar you mean uds variable, than there should be no problem with such approach.
Once you calculate it, uds will store data.

Best regards
